Temperature transmitters are key components in electronic measurement systems. Their main function is to convert the sensor signal into a standardized output, widely used in industry, thus ensuring efficient integration with control and monitoring systems.
Digital indicators manufactured by WIKA, Winters and Noshok are available in various versions. Some models are designed to be integrated directly into the sensor head, optimizing space and facilitating installation. In addition, certain versions include advanced functionalities, such as:
- HART® communication for integration into more complex systems.
- Selection of sensor type.
- Adjustment of the measuring range (span).
- Configuration of error signaling.
- Identification of the measurement point.
- Switched outputs, which add flexibility in specific applications.
These instruments are essential in sectors such as the food, petrochemical, chemical and water treatment industries, where accuracy and reliability in temperature measurement are critical to ensure quality and operational safety.
