Rochester S281 Coolant Level Sensor

The S281 is an active device designed to give an alarm signal if coolant 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 output.

 

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.
