Temperature sensors are crucial components in process instrumentation, used to measure and monitor temperature in various industrial and scientific applications.
There are several types of temperature sensors commonly employed in process instrumentation, including:
- 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 sensors are available across all the technologies mentioned above, offering flexibility to meet the specific requirements of various industries.
Applications Include:
- Monitoring temperature throughout processing stages to ensure quality, safety, and repeatability
- Optimising process conditions by providing real-time temperature data for control and adjustment
These sensors are critical for maintaining process consistency, ensuring product quality, and meeting regulatory standards.
Communication Options Include:
- 4–20 mA analogue outputs
- HART, I/O Link, ProfiBUS PA, ProfiNET, and Foundation FieldBUS
Approvals
Temperature sensors are available with ATEX (for hazardous environments) and WRAS (Water Regulations Advisory Scheme) certifications to ensure compliance with industry standards.
