OPTITEMP TT 51 C/R Temperature transmitter
2-wire temperature transmitter for resistance or voltage measurement  - KROHNE MESSTECHNIK GMBH


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. 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. They are compatible with the HART® 6 protocol offering extended diagnostic information (device error, sensor and wiring conditions). : 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 : Dual sensor input with for example Pt100, 2-,3- & 4-wire (TT 51 R), T/C, resistance and voltage : Sensor drift detection: one sensor with double elements, monitoring the temperature difference : SIL 2 (according to IEC 61508) : ATEX (intrinsically safe and non-incendive); In preparation: FM, CSA, IECEx and GOST
