:: High accuracy and long-term stability
:: Proven reliability due to robust design and dual sensor backup
:: Sensor isolation monitoring (SmartSense)
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(R) 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.
Features
High measurement accuracy
:: Long-term stability: drift over 5 years is the maximum of ±0.05degC or ±0.05% of span
:: High precision: ±0.1degC / ±0.18degF or 0.05% of span (example Pt100)
:: Low temperature drift: ±0.005% of span per degC or degF
High reliability
:: Dual sensor input with for example Pt100, 2-,3- & 4-wire (TT 51 R), T/C, resistance and voltage
