What are the common measurement terminologies that are used in instrumentation? Measured Variable: It is the physical quantity or condition, which can be measured by the instrument. Measured variables such as temperature, pressure, rate of flow, level, speed, etc. Input Signal: It is a signal applied to a device element or system. It is applied …
What is Instrument Air? Most power plants and process industries require the instrument air to run their process.  The instrument air is compressed air that is free from moisture and dust particles. The pneumatic equipment such as control valves, solenoid-operated valves, cylinders, actuators, and positioners require the instrument air to control the process. It is …
Auxiliary Contact: What is Auxiliary contact? Auxiliary contacts are supplementary contacts that are added to a circuit to protect the main contact. This accessory allows you to check the status of a Miniature Circuit Breaker or Supplementary Protector from a remote. Simply explained, it aids in remotely determining whether the breaker is open or closed. …

A miniature circuit breaker can provide much more than current protection, it can also provide remote tripping, status indicator, under-voltage/overvoltage protection, and other features. What is Auxiliary contact? Auxiliary contacts (or switches) are supplementary contacts that are added to a circuit to protect the main contact. This accessory allows you to check the status of a …

Trip Curve of MCB: The Trip Curve is a graphical representation of the circuit protection devices. Fuse, MCB’s, MCCB’s, supplementary protectors, motor protection circuit breakers, overload relays, electronic fuses, and air circuit breakers are all examples of circuit protection devices. The multiples of the current going through the miniature circuit breaker are represented on the horizontal X-axis. …

What is MCB? A miniature circuit breaker is an automatically operated electrical switch used to protect low voltage electrical devices from fault due to overload or short circuit. The typical current rated upto 125A, above 125A of typical current MCCB can be applied. Fault zone can be easily identified. MCB are protective than the fuse. …
