OPTITEMP TT 31 R Universal Temperature Transmitter

Brand: Krohne
Request Information
Transmitters in the OPTITEMP TT 31 R series are universal, separate 1 and 2 channel two-wire transmitters, available for both ex and non-ex applications. 

For hazardous (Ex) applications, no zener barriers or intrinsically safe power supply units are necessary, considerably reducing the costs for purchase and servicing. 

The TT 31 R is designed to be mounted on DIN rails.
Features
  • Extremely cost-efficient solution for hazardous (Ex) applications
  • Completely universal, linearized and isolated
  • Input: resistance thermometers, thermocouples, mV and ohms
  • Sensor and system error correction (sensor/transmitter) for maximum accuracy
  • Complete access to all functions during operation
  • Constant sensor break function
  • Simple loop checking with calibrated output
  • User-friendly Windows configuration software
  • Only 11 mm per channel (2-channel version)
  • Permanent or removable connections
