Temperature Transmitters
Temperature transmitters for all industrial applications
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.

Portfolio description
Our iTEMP® temperature transmitter offering covers a large selection of models, housings, approvals and communication standards:
DIN rail mounted temperature transmitters for panel installation
Temperature transmitters for direct installation in thermometer form B terminal heads
Field housings for direct connection in process areas
Temperature transmitters for hazardous areas
Secure Bluetooth® interface option for remote parametrization
Seamless system integration with common communication protocols
The configurable transmitters not only transfer converted signals from resistance thermometers (RTDs) and thermocouples (TC), but also resistance (Ω) and voltage signals (mV) . In order to obtain the highest measurement precision, linearization characteristics for every type of sensor are stored in the transmitter.
In process automation, two measurement principles for temperature have asserted themselves as a standard:
RTD - Resistance temperature detectors: Measuring principle
The RTD sensor changes the electrical resistance with a change in temperature. They are suitable for the measurement of temperatures between -200 °C and approx. 600 °C and stand out due to high measurement accuracy and long-term stability. The sensor element most frequently used is a Pt100. As a standard, Endress+Hauser RTD sensors fulfill the IEC 60751 accuracy class A.
TC - Thermocouples: Measuring principle
A thermocouple is a component made of two different metals connected with each other at one end. An electrical potential (thermoelectric force) is caused due to the Seebeck effect at the open end if the connection and the free ends are exposed to different temperatures. With the help of the so-called thermocouples reference tables (see IEC 60584) the temperature at the connection (measuring junction) can be concluded.
Thermocouples are suitable for temperature measurement in the range of 0 °C to +1800 °C. They stand out due to the fast response time and high vibration resistance.
