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.
