OPTITEMP TT 11 C/R Analog Temperature Transmitter

Brand: Krohne
Request Information
The OPTITEMP TT is an Analog, multirange 3-wire temperature transmitter which works together with single resistance thermometers of the type Pt100 and Pt1000.

A special feature of the device is its 0-10 Vdc output that predestines it for the HVac systems in building services applications. The transmitter has a high reliability and a good industrial performance.

The OPTITEMP TT series consists of 2 different versions in terms of the mounting. The TT 11 R is the rail-mount version for DIN rails whereas the TT 11 C is primarily intended to be mounted in a "B connection head" or larger according to DIN 43729.

As an alternative you can also mount the in-head version on a DIN rail according to DIN 50022 / EN 60715 with the help of an optionally available rail mounting kit.
Features
  • 0-10 Vdc output for building services applications
  • Rangeable with solder pads and potentiometers
  • Temperature linear output for Pt100 and Pt1000
  • Sensor break monitoring
  • Polarity protected power supply
  • Easy wiring, in-head version with large center hole
  • In-head version with moulded electronics for high protection
