Difference between Soft Starter and VFD

Both soft starter and VFD can start and stop the motor but the main difference is VFD can do the speed control of motor also.

A megger is used to measure insulation resistance and it is powered by a DC generator or battery of a higher voltage range.

Calibration plays an important role in quality control. If an instrument is not calibrated we may suffer loss of our health, money or safety.

Any measurement has two parts – a number and a unit of measurement. The unit of measurement is very important in calibration.

A memristor controls the flow of current in a circuit and also remembers the amount of charge that has previously flowed through it.

We compare the reading of Unit Under Calibration (UUC) with reference to Master Instrument. Therefore the selection is very important.

You measure a lot of things daily. When did man measure something for the first time? Let’s learn the history of measurement.

Describe in detail the effect this calibration error will have on the performance of the analytical process control system.

In this article, we discuss about positive displacement pumps and their types used in process control industries.

DeviceNet is a digital, multi-drop network to connect different devices like actuators, sensors, and automation systems of multi-vendors.
