Process temperature can be measured using various techniques. The most common are:
- Thermocouples: Consist of two dissimilar metals that generate a voltage proportional to the temperature difference, offering durability, a wide temperature range, and fast response.
- Resistance Temperature Detectors (RTDs): Use the change in resistance of a pure metal (usually platinum) to measure temperature, providing high accuracy and stability for precise measurements.
- Thermistors: Semiconductor devices with resistance that varies with temperature, offering high sensitivity but a more limited temperature range than RTDs and thermocouples.
- Infrared (IR) Temperature Sensors: Measure temperature remotely by detecting thermal radiation, ideal for non-contact measurements or when direct contact is not possible.
Temperature switches are devices that monitor process temperatures and activate a relay, voltage, or current output when a predefined temperature threshold is reached. These switches are essential for maintaining safe and efficient operations across a wide range of industrial applications.
Applications Include:
- Process heating control: Regulating temperatures to maintain optimal processing conditions
- Safety monitoring: Detecting temperature deviations to prevent equipment damage or system failures
- Plant operation safety: Ensuring safe operation by triggering alarms or system shutdowns when critical temperature limits are exceeded
Communication Options Include:
- 4–20 mA analogue outputs
- PNP digital outputs
Approvals
