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 transmitters convert signals from temperature sensors, such as thermocouples, RTDs, thermistors, or IR sensors, into standardised communication protocols widely used in industrial and scientific applications. Many transmitters also feature displays to provide real-time temperature readings to users.
Applications Include:
- Measuring and monitoring temperature across industrial and scientific processes
- Ensuring process quality, safety, and repeatability by providing accurate and reliable temperature data
These transmitters are critical components for maintaining operational efficiency and compliance in temperature-sensitive applications.
Communication Options Include:
- 4–20 mA analogue outputs
- HART, I/O Link, ProfiBUS PA, ProfiNET, and Foundation FieldBUS
Approvals Include:
- ATEX certification for use in hazardous environments
- WRAS certification for compliance in water-related applications
