2-wire transmitter for temperature, resistance or voltage measurement
- 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® 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 ±0.05°C or ±0.05% of span
- High precision: ±0.1°C / ±0.18°F or 0.05% of span (example Pt100)
- Low temperature drift: ±0.005% of span per °C or °F
High reliability
- Dual sensor input with for example Pt100, 2-,3- & 4-wire (TT 51 R), T/C, resistance and voltage
