Uehling Instrument Company Float switches are used to trip high/low level alarms, engage relays, control or start/stop pumps, open/close valves etc. They are a simple, inexpensive way to provide independent or redundant setpoints for emergency shut-down or backup

Float switches are often furnished with Level Alert Alarm Systems to provide an audible, visual and relay output response to high/low and other alarm conditions. These microprocessor based alarm systems are expandable and may be activated by: Continuity, AC or DC Voltages, and Current Loops. (See Uehling Bulletin 492P98).

Level Alert Alarm Systems may be optionally provided in convenient factory-assembled NEMA 12 Oil Tight, NEMA 4X Watertight and NEMA 7 Explosion Proof enclosures.
