Rochester S275 Coolant Level Sensor

The S275 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 provides 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.

 

The switch is designed to operate in both earthed metal and isolated plastic tanks. For high accuracy the S275 is ideally mounted horizontally at the point where an alarm or control signal is required. However, the switch can be mounted vertically – contact for more information.
