Intelligent two wire universal transmitter

• High accuracy and long-term stability
• Universal input
• Efficient PC-configuration without external power

The TT 33 is a universal, intelligent, programmable and isolated 2-wire transmitter for temperature, resistance or voltage measurements in an industrial environment.

The TT 33 series consists of 2 different versions in terms of mounting. The TT 33 R is the rail mount version whereas TT 33 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.

The whole TT 33 transmitter series combines competitive pricing, functionality and simple configuration. Useful error correction functions like the automatic correction of known sensor errors improve the accuracy. Typical characteristics are the high accuracy, stability and reliability combined with a robust housing.
