The task of the temperature transmitter is to convert the sensor signal to a stable standardized signal. However, modern transmitters using digital technology are not only: they are intelligent, flexible and provide high measurement accuracy. They are an important part of the measurement chain, which can improve the safety and efficiency of the process.

 

Our extensive modular industrial temperature transmitter product portfolio provides:
DIN guide rail installation temperature transmitter used for panel installation
The head temperature transmitter directly installed in the end of the thermometer
Live temperature transmitter used to directly connect to the area of the area
Explosion -proof area temperature transmitter

 

 

The configuration transmitter not only transmits a conversion signal from the resistor temperature meter (RTD) and thermocouple (TC), but also transmits the resistor (ω) and voltage (MV) signals. In order to obtain the highest measurement accuracy, the linear characteristics of each type of sensor are stored in the transmitter.
 
In process automation, the two temperature measurement principles have become standard:
 
RTD -resistance temperature detector: measurement principle
The RTD sensor changes the resistance with the change of temperature. They are suitable for the temperature between -200 ° C to about 100 ° C. 600 ° C stand out due to its high measurement accuracy and long -term stability. The most commonly used sensor element is PT100. As a standard, Endress+Haser RTD sensor meets the IEC 60751 accuracy level A.
 
TC -thermocouple: measurement principle
The thermocouple is a component made of two different metals, and one end of them is connected to each other. If the connector and the free end are exposed to different temperatures, the Pedber effect on the open end will generate an potential (thermal potential). With the so -called thermocouple reference table (see IEC 60584), the temperature of the connection (measurement node) can be obtained.
 
The thermocouple is suitable for temperature measurement in the range of 0 ° C to +1800 ° C. They stand out due to their rapid response time and high vibration resistance.
