This fill with high and low alarm and Heater cut-out is a popular product we provide to OEMs that are putting submersible heaters into the environments. The heater cut-off is the longest sensor rod in the sensor head. The control has four different outputs and the most sensors of any other kit we offer.


The system monitors for a high water level condition, a low water level condition and a Low-Low Level condition for Heater Cut-Off.
These conditions have three outputs each which:

  1. Close a set of dry contacts for the BMS
  2. Operate a relay rated at 30AMPS / 250VAC
  3. Turn on an LED to indicate the sensor has tripped
  4. Activate when the water falls to a lower set point than the low alarm
    When this fourth set point activates it removes power from the Heater in the basin by opening a normally closed relay, closing a set of dry contacts and turning on a red LED

The Control Panel has visual display indication for power to the level control panel, when the control panel is actively filling, high and low water alarms and when the control panel has disengaged the heater in the catch basin.

*Custom Sensors lengths available upon request.
