Thermatel Model TD1/TD2 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.
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
Detects minimum flow or presence / absence of flow
Easy / fast calibration
Excellent low flow sensitivity
