What is Total Quality Management (TQM)?

Transparent energy monitoring reduces both machine standstills and the necessity to oversize the corresponding components for reasons of plant availability. Added to that are the preventive maintenance and ultimately a considerably increased production efficiency.

With its portfolio of integrated power measurement, Beckhoff simplifies energy management while at the same time optimizing the availability of machines and plants.

Due to the continuous, system-integrated power measurement, deviations from the standard state can be detected quickly, thus enabling quick intervention. For example, the continuously increasing current consumption of a machine may indicate bearing wear. On the other hand, a decreasing current consumption may indicate quality problems, which need to be corrected at an early stage.

By monitoring the power supply, erroneous behavior can be attributed to a possible phase failure in the power grid. The speed of reaction is reduced and possible downtimes are avoided. Scalability is a principle at Beckhoff: This also applies to the EtherCAT power measurement terminals, which cover applications from simple grid monitoring to power monitoring in all areas of application.

They are scaled by different levels of performance in terms of measuring accuracy, measuring speed, and measured and internally calculated values. A software library for power monitoring for our TwinCAT automation software also rounds off the power measurement. Suitable accessories are available for additional safety in the control cabinet. This results in a complete power measurement portfolio, so that all components can be procured from a single source.

There is a wide variety of requirements in energy management in the machine environment and in the energy economy, ranging from pure grid monitoring and process control through to high-end power monitoring.

The EL34xx and EL37x3 energy and power measurement terminals set different focal points and are therefore designed for a wide range of applications. Starting with simple threshold checking for voltage, frequency and phase with output of warning and status bits with IoT and energy management projects with the EL The EL and EL are also the right terminals for high-feature applications for 3-phase grids, which pre-process the measured current and voltage values internally and thus provide the controller with up to values for extensive grid analysis, as well as for energy management.

The EL and EL can be used for power monitoring with oversampling function. This allows current and voltage to be measured simultaneously at speeds of up to 10 kSps on all channels for temporally precise state detection. Distributed power measurement can be realized with the EL in combination with the EL, so that effective power values can be calculated with spatially separated voltage and current measurement.

The EL pure current measuring terminal can be positioned as often as desired in a grid. To calculate the real power data, the required voltage values are transmitted from the EL three-phase power measurement terminal, which is installed once only in each grid.

This concept of distributed power measurement — with just one EL and any number of ELs — reduces the hardware and installation expenditure to a minimum. Beckhoff's energy and power measurement portfolio also features products for the medium voltage level.

Voltages in the medium voltage level can simply be connected to our terminals with a measuring range of up to V AC via standard voltage transformers with a V or V output.

Calibration of the terminals is necessary in some applications if, for example, knowledge of the measuring behavior and uncertainty is to be gained for quality reasons. We can also meet these requirements with our calibrated power measurement terminals. With the SCT current transformers, Beckhoff, as a system provider, offers the possibility to implement reliable power sensors as an integral part of the PC-based controller directly in the field and completes the measuring chain from the recording of the physical measurement value to the data transmission to the cloud.

Users can choose between different concepts, each of which are highly scalable via different designs and performance classes and are therefore suitable for any application. For current intensities from 1 to 5, A, as well as from ring-type and split-core current transformers up to 3-phase transformers.

The SCT series is extremely diversified and offers low-cost transformer sets for building services, standard industrial transformers for mechanical engineering and solutions for test benches with particularly high requirements for accuracy.

Decisive for the selection of the suitable variant is the respective type of use. Whereas the data acquisition can be implemented cost-efficiently and with high measurement accuracy, in particular in new systems, using the ring-type current transformers, the split-core current transformers are ideal for use as an uncomplicated retrofit solution due to the simplicity of their attachment.

Function blocks are available for calculating RMS values for current, voltage and power. These can be output as instantaneous or average values. Maximum and minimum values are also available on the function block.

Frequency and frequency spectra can be determined, such as e. All blocks are available for single-phase and 3-phase systems. For this purpose, Beckhoff offers various options for marking the power measurement terminals. A further possible separation can be realized via the EL separation terminal.

This passive terminal has an orange front panel and additionally provides for optical separation. The third option can be implemented by the BZ plug-in label cover. The transparent cover is marked with "High Voltage!

In order to simplify the assessment of current performance values for the user as much as possible, Beckhoff has developed the so-called Power Quality Factor PQF. For example, if an error occurs on a machine and the PQF drops to zero at the same time, it can be concluded that it is probably not the machine itself, but a change in the power supply that caused the error. In this way, not only the signs and effects of a fault can be rectified more quickly, but above all the causes.

At the same time, a falling PQF can be used as an early warning system. By completing the power measurement chain from the sensor to the cloud, PC-based control specialist Beckhoff simplifies energy management approaches and improves the availability of machines and production facilities.

Romande Energie SA, one of the five largest energy utilities in Switzerland, employs EL power measurement terminals and other EtherCAT Terminals from Beckhoff in its substations to safeguard the availability of its grid. This is implemented with the help of a secondary data acquisition system that can compensate for partial or total failures of the primary acquisition path. In conjunction with a new building for switchgear production, international company Hermos AG realized an advanced energy center at its Mistelgau, Germany site.

PC-based control technology from Beckhoff offers a common platform for automation and building management. The drying and processing of wood is a process that requires a lot of energy. Holzwerke Weinzierl GmbH in Germany nevertheless manages to generate more power than it consumes. The voltage is measured internally via direct connection of L1, L2, L3 and N. The current of the three phases L1, L2 and L3 is fed via simple current transformers.

The measured energy values are available separately as generated and accepted values. In the EL Terminal, the effective power and the energy consumption for each phase are calculated. In addition, an internally calculated network quality factor provides information about the quality of the monitored voltage supply. The EL offers basic functionality for mains analysis and energy management. The voltage is measured via direct connection of L1, L2, L3 and N.

All measured currents and voltages are available as root-mean-square values. In the EL terminal, the effective power and energy consumption for each phase are calculated. The EL offers extended functionality for mains analysis and energy management. The current of up to six phases is fed via simple current transformers.

With up to V AC, the voltage inputs are optimized for the direct monitoring of high-capacity generators, as in the wind power industry, for example. No upstream voltage transformer is required. The four current inputs are electrically isolated so that the terminal can be used in all common grounded current transformer configurations such as 2- or 3-transformer configurations with star or delta connection incl.

The EL can be used for simple grid analysis up to the 63 rd harmonics analysis. Alternatively, all readings can be combined in a power quality factor for simplified diagnostics. Like all measured terminal data, the harmonic content can be read via the process data. The adapted voltage measuring range to V is optimally suited for connecting medium voltage transformers, for example.

The internal measured values are compared with threshold values preset by the user. The result is available as digital information in the process image. The EL checks for the correct phase order L1, L2, L3, phase failure, undervoltage and overvoltage, and possible phase asymmetry.

An error bit is set in the case of an incorrect phase order or the failure of a phase. Should, for example, an asymmetry or voltage error occur, only a warning bit is set initially. In addition, an internally calculated mains quality factor provides information about the quality of the monitored voltage supply.

The EL offers basic functionality for mains monitoring and analysis. In addition, the version also outputs current RMS values of the voltage in the process image. The control system has sufficient computing power for true RMS or performance calculations and complex custom algorithms based on the measured voltages and currents.

Through the oversampling principle, the terminal is able to measure at significantly shorter intervals than the cycle time of the control system. AC and DC parameters must be connected and measured with a common reference potential. A removable terminal enables pre-wiring. The SCT2xxx series offers a wide selection and impresses with innovative, screwless connection technology.

The separable measuring system of the SCT6xxx series enables flexible retrofitting without disconnecting the primary conductor. The SCT7xxx series supports the highest primary currents and is suitable for convenient retrofitting. The SCT0xxx series is specially designed for low primary currents and is used for corresponding applications. Function blocks are available for the calculation of RMS values for current, voltage and power.

The Importance of Measurement in Manufacturing

Jump to navigation. Despite the importance of having good management control systems MCSs , management critics have argued that adding controls does not always lead to better control and that the MCSs in common use cause managers to be excessively short-term oriented or are prone to stifle creativity and initiative. An old narrow view of a MCS is that of a simple cybernetic regulating system, involving a single feedback loop thermostat. This book takes a broader view and recognizes that some management controls are proactive rather than reactive. Proactive means that the controls are designed to prevent problems before the organization suffers any adverse effects on performance. Management literature includes many definitions of management.

Functions of Management

The proper performance of the management control function is critical to the success of an organization. After plans are set in place, management must execute a series of steps to ensure that the plans are carried out. The steps in the basic control process can be followed for almost any application, such as improving product quality, reducing waste, and increasing sales. The basic control process includes the following steps:. Consider a situation in which a fictional company, The XYZ Group, has suffered a decrease in the profits from its high-end sunglasses due to employee theft.

Achieve precision measurement and process control by ensuring you have the right flow technology for your specific needs. Flow Measurement is the process of measuring fluid in your plant or industry. You can measure flow through a variety of different devices such as Coriolis, differential pressure, vortex, magnetic, ultrasonic, turbine and positive displacement meters.
