What are thermocouples used for?

Thermocouples are common temperature sensors used in a wide variety of commercial and industrial applications. While slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range, are self-powered, and have a fast response time. Their simple construction make them inexpensive and durable.

How to calculate thermocouple temperature?

As mentioned in the previous section, the proper method to calculate the thermocouple temperature follows.A simple addition between the equivalent thermocouple temperature and the cold-junction temperature would have resulted in 625°C. This would have produced a 1.5°C error because of the thermocouple non-linearity over temperature.

What is a time constant in a thermocouple?

A time constant has been defined as the time required by a sensor to reach 63.2% of a step change in temperature under a specified set of conditions. Five time constants are required for the sensor to approach 100% of the step change value. An exposed junction thermocouple offers the fastest response.

What is thermocouple measurement circuit with thermistor cold-junction compensation?

Thermocouple Measurement Circuit With Thermistor Cold-Junction Compensation Similar to the RTD, thermistors are sensors that have a resistance that vary with temperature. The thermistor may be a PTC type (positive temperature coefficient) or an NTC type (negative temperature coefficient).
