S285 Capacitance Type Coolant Level Switch

The S285 is an active device designed to give an alarm signal if liquid falls below, or rises above, a preset level. It can be specified with a delay to eliminate false alarms due to turbulence.
Containing a factory programmable microprocessor, the switch offers sink to ground or source voltage outputs, or even both outputs on separate pins.
Its small footprint with limited intrusion into the tank means a reduced risk of damage and a wide range of customer specifiable options make it suitable for most applications.
