S28x Capacitance Coolant Level Switches

Amphenol Rochester Sensors S28x Capacitance Coolant Level Switches are active devices designed to give an alarm signal if liquid falls below or rises above a preset level. These can be specified with a delay to eliminate false alarms due to turbulence. Containing a factory-programmable microprocessor, the switches offer sink-to-ground, source-voltage, or both outputs on separate pins.
