How to make connection between thermocouple and PLC.

Connection between thermocouple and PLC is an important thing to consider. The cost & efficiency both factors are needed to take in to consideration. Also the environment (temperature) of the sensor location, distance to the PLC is a factor. Thermocouple connection in a system comprises with connection channel cable and cold end temperature generator usually…


Difference between RTD and Thermocouples

Difference between resistence temperature detector and thermocopuples are listed below, Temperature range: First, consider the difference in temperature ranges. Noble Metal Thermocouples can reach 3,100 F, while standard RTDs have a limit of 600 F and extended range RTDs have a limit of 1,100 F. Cost: A plain stem thermocouple is 2 to 3 times…


What is a Thermocouple?

A Thermocouple is a sensor used to measure temperature. Thermocouples consist of two wire legs made from different metals. The wires legs are welded together at one end, creating a junction. This junction is where the temperature is measured. When the junction experiences a change in temperature, a voltage is created. The voltage can then…
