OPTITEMP TT 20 Analog Temperature Transmitter

Brand: Krohne

The OPTITEMP TT20 is an Analog, multirange 2-wire temperature transmitter for temperature measurement with a Pt100 resistance sensor. 

The main field of application is industrial environment, therefore the device has a high reliability and an excellent industrial performance. 

The transmitters can easily be configured from a PC by using the optionally available ConSoft program and a transmitter configuration kit ICON. Easily set and re-set the parameters like temperature measurement range, TAG identity and failure indication. 

When transmitters are configured from PC no calibration is necessary. 

The TT20 combines competitive cost with easy and user friendly functionality and configuration in robust environments with reliable accuracy during the lifetime.
Features
  • Sensor break monitoring 
  • Sensor error correction 
  • Configuration without external power
