OPTITEMP TT 11 C/R Analog Temperature Transmitter
Brand: KrohneThe 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.
