Fluid Defender Level Sensor monitors lubrication fluid tank levels in above ground, stationary tanks. This high level sensor provides signal to Fluid Defender when a tank becomes full, warning of potential overfilling. The high level sensor detects when a tank reaches full capacity and you can adjust the height of the sensor within the tank to receive a fill warning at a desired fill level.
For high level sensors the float is in the down position and the sensor contacts are closed during normal operation. When the float moves to the up position and the sensor contacts are open during a high level condition, triggering the Fluid Defender alarm. The 25V475 can also be uses as a control level sensor to angle the output of the air control solenoid valve.
