Signal Outputs (Reed Switch):
Normally Open Operation: Orientate the switch such that float swings down when the switch is dry. In the dry state, the float rests in the lowest position and the circuit is open.

Wiring to a OMEGA ENGINEERING Controller:
OMEGA ENGINEERING controllers have a
OMEGA ENGINEERING manufactures a wide range of liquid level sensors and technologies. While each of these sensors is designed to operate in a wide variety of applications, it is the user’s responsibility to select a sensor model that is appropriate for the application, install it properly, perform tests of the installed system, and maintain all components. The failure to do so could result in property damage or serious injury.
Proper Installation and Handling:
Because this is an electrically operated device, only properly trained staff should install and/or repair this product. Use a proper sealant with all installations. Never overtighten the sensor within the fitting, beyond being hand tight. Always check for leaks prior to system startup.

Contact Protection (Reed Switch):
When current is interrupted, the inductance of the load generates a high frequency voltage, which appears across the switch contacts. If the voltage is large enough, it can cause arcing. Arcing can cause the contacts to weld to each other resulting in unreliable switching per- formance. It is essential to protect the circuit, by suppressing the volt- age to prevent arcing.
This can be accomplished through the use of a diode for DC circuits and a
