The TD1/TD2 Thermatel switch is extremely versatile providing flow/level/interface detection in a single unit. Both liquid and gas flow detection is obtainable. The TD1 is available with 24 VDC power with the TD2 available in either an AC or DC version. The TD2 also provides LED indication through an optional glass window, mA output for diagnostics or repeatable flow/level indication, optional hermetically sealed relay, time delay adjustment, and remote electronics. Continuous diagnostics on both units provides assurance that the switch is operating properly.
