4–20mA sensor transmitters are very common in industries to measure physical parameters such as pressure, temperature, flow, etc. Based on how they are connected to the process control and automation…
4-20mA Current loops are widely used to transmit process variable data such as temperature, pressure, flow rate, level, consistency, speed, etc between the process controllers and the field devices. Transmitters…
A Rogowski coil is an electrical transducer, that functions similar to a current transformer and is used in a variety of applications to measure alternating current (AC). It is named…
What is an instrument transformer? Instrument transformers are current and voltage transformation devices that are used to step down the transmission and distribution line voltages and currents to levels that…
Potential transformers (PT) or voltage transformers are instrument transformers used for voltage measurements. They are connected in parallel to the line and operates under the same principle of power transformers.…
What is a current transformer? A current transformer is a type of instrument, used to measure or sense large alternating currents by scaling it to a smaller, safer and measurable…
The bipolar junction transistors exist as NPN and PNP types. This article intents to help you understand the difference between these two types and how to use them in a…
Proximity sensors are used to detect the presence of an object without any direct contact. It is used as an alternative to the limit switches. There are various types of…
