Temperature transmitters act as an interface between a temperature sensor and the display or control device. They convert the output signal of the sensor, a non-linear millivolt signal, into a linear milliamp signal which can be sent longer distances without degrading which results in more accurate measurements as well as a signal that can provide a platform for digital communications such as HART or Fieldbus.

The task of a temperature transmitter is to convert the input signal from temperature sensors such as RTDs and thermocouples into a stable and standardized output signal. However, modern transmitters using digital technology are more than just that: they are intelligent, flexible and offer high measurement accuracy. They are a crucial component of the measurement chain capable of improving safety and efficiency in your process.
