Request Information

TD1 and TD2 Thermal Dispersion flow/level/interface switches provide a new level of performance and reliability not found in previous switches. Continuous diagnostics with fault indication, temperature compensation, narrow hysteresis and fast response time make the TD1/TD2 the latest in thermal dispersion switch technology.

TD1 is a basic switch with 24 VDC power and an 8-amp DPDT relay. The TD2 adds LED indication through a glass window, ability to electrically measure the set point, mA output for diagnostics and trending, optional hermetically sealed relay, plus time delay. A universal AC power supply simplifies installation.

Thermatel® probes are available in 316 Stainless Steel, Hastelloy® C, or Monel®with all welded construction.

FEATURES

  • Temperature compensated to provide repeatable alarm under varying process temperatures
  • Continuous diagnostics detect sensor fault
  • Non-linear mA output signal can be used for trending, diagnostics and repeatable flow/level indication (TD2)
  • Detects minimum flow or presence/absence of flow
  • Easy/fast calibration
  • Excellent low flow sensitivity
  • Optional hot tap available (see bulletin 41-103)
  • Hygienic design available
  • NACE construction available (consult factory)
  • Process temperatures from -100° to +400° F (-73° to +204° C)—High temp. version to +850° F (+454° C)
