The MLS-020-TF Liquid Level Switch is float activated to operate an electrical SPDT reed switch for annunciation/pilot signal for indication of high level to an annunciator, controller or PLC. The MLS-020-TF connects directly into the gas scrubber wall and can be used with an FW Murphy weld collar or external float chamber.

The MLS-020-TF's process connection is 2 in. NPT. The test button tests for float function; the complete mechanism including the magnetic activation of the reed switch; and the wiring from the switch to the control panel.

Features of the MLS-020-TF include:

* Clean magnet design virtually eliminates iron filing accumulation on the magnet

* Seal-free construction

* ANSI/ISA 12.27.01 compliant (Single Seal)

* Push button to test functions
