OPTITEMP TT 51 C/R 2-wire Temperature, Resistance & Voltage Transmitter

Brand: Krohne
The TT 51 series is a universal, isolated, dual-input transmitter for temperature, resistance or voltage measurements of solids, fluids and gases in an industrial environment.

The TT 51 series consists of 2 different versions. TT 51 C is primarily intended to be mounted in a DIN-B housing whereas TT 51 R is the rail-mount version.

This transmitter family utilizes a modular design in hardware as well as in software to ensure the quality and reliability of the transmitter signal output.

The transmitters are compatible with the HART® 6 protocol offering extended diagnostic information (device error, sensor and wiring conditions).

Typical characteristics are the high accuracy, stability and reliability combined with a robust housing.

The double inputs enable new safety features such as sensor backup and sensor drift monitoring.
