Rochester Sensors' S285 capacitance type coolant level switch 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 outputs. The switch is designed to operate in both earthed metal and isolated plastic tanks. For high accuracy the S285 is ideally mounted horizontally at the point where an alarm or control signal is required.
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.
Note: Used with water based liquids, such as coolant or washer fluid, compatible with brass, PTFE, EPDM and FVMQ. Includes HA/43 Harness (FZHA43), C/K1 4-Way Metri-Pack 150 Mating Connector on 100 mm. Flying Leads.
