S286 Oil Level Switch – Capacitance Type
Oil Level Switch providing sink and/or source output. Fitted with integrated Delphi Metri-pack 150 series 4 pin connector.
The S286 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 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.
For high accuracy the S286 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.
