S292 Oil Level Switch – Capacitance Type with Complementary Voltage Output.

Oil Level Switch providing complimentary (flip/flop) voltage outputs. Fitted with integrated Delphi Metri-pack 150 series 4 pin connector.

The S292 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 a complementary voltage output on two 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.

The switch is designed to operate in both earthed metal and isolated plastic tanks. For high accuracy the S292 is ideally mounted horizontally at the point where an alarm or control signal is required. However, the switch can be mounted vertically – contact Fozmula with your application requirements
