Temperature transmitter is to amplify the electrical signals from the sensor, to correct and depending on the model galvanically

Temperature transmitter is to amplify the electrical signals from the sensor, to correct and depending on the model galvanically insulate them. The conditioned signal can then easily be transmitted over long distances to the in-/output sections of a process control system or controller. Since the electrical signal from the thermocouple or resistance thermometer is relatively strong, signal amplification in close proximity to the sensors is not required

Resistance thermometers, also called resistance temperature detectors or resistive thermal devices (RTDs), are sensors used to measure temperature by correlating the resistance of the RTD element with temperature. Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it. The RTD element is made from a pure material whose resistance at various temperatures has been documented. The material has a predictable change in resistance as the temperature changes; it is this predictable change that is used to determine temperature.
