Head Pressure Switch

The LC40 is a low-pressure level control for atmospheric storage tanks. The LC40 monitors the level of a tank by sensing the head pressure created by the height of the fluid in the tank. When equipped with an SPDT switch, the LC40 can be set to trigger at any level on rise and fall. The hinged door provides both a weather seal and quick access to the internals for trigger point, zero calibration and span adjustments.
