Model TD2

Brand: Magnetrol
Request Information
Thermatel® TD2 switch can easily be adjusted to detect flow (gases and liquids), level or liquid-liquid interface. 

The TD2 is either Vdc or Vac line powered, has integral or remote electronics and offers additionally LED indication, time delay and mA output for diagnostics and trending. 

With continuous diagnostics, automatic temperature compensation, narrow hysteresis and fast response time, the TD2 brings you the latest in thermal dispersion technology.
Features
  • Easy field calibration – pre-calibration from factory at request.
  • Variable flow or Flow/No flow detection of gases and liquids.
  • Excellent low flow sensitivity.
  • Automatic temperature compensation for repeatable alarm under varying process temperatures.
  • Continuous diagnostics detect sensor fault.
  • Continuous monitoring of flow rate versus setpoint via LED (TD2).
  • mA output provides repeatable indication of flow rate and fault detection (TD2).
  • Flow can be measured over test points (TD2).
  • Optional retractable fitting for dismantling under process conditions.
  • Process conditions up to +450 °C (+850 °F) and 414 bar (6000 psi).
  • Integral or remote electronics up to 150 m (500 ft).
  • Unique spherical tip design option ideal for liquids or high viscosity applications.
  • Suited for SIL1 and SIL2 loops (full FMEDA report available).
