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 S275 is a horizontally mounted switch for sensing water/coolant levels. Fitted with a Packard connector all models have a factory programmable time delay to reduce the risk of intermittent switching through liquid turbulence. The S275 is available with a wide selection of mounting thread and switching options.
