Ürün Açıklaması

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
  • Sensor drift detection: one sensor with double elements, monitoring the temperature difference
  • Sensor backup: automatic switchover to backup sensor
  • Robust design: 10g vibrations, 95% RH and robust terminals

High safety

  • SIL 2 (according to IEC 61508)
  • NAMUR compliant to NE 21, NE 43, NE 53, NE 89 and NE 107
  • ATEX (intrinsically safe and non-incendive); In preparation: FM, CSA, IECEx and GOST

High user efficiency

  • Easy configuration, installation and maintenance with ConSoft, HART®6 protocol, EDD plus
  • DTM/FDT enabled systems
