MODEL KUST ULTRASONIC SWITCH

INSTALLATION / OPERATION INSTRUCTIONS

GENERAL DESCRIPTION

The KUST Series Ultrasonic Level Switches are ideal, low cost solutions for many liquid level control applications. They

operate in a wide variety of services.

PRINCIPLE OF OPERATION

Ultrasonic switches use piezoelectric crystals to transform electrical energy into mechanical motion (sound). The

Transmit Crystal sends a pulse of sound through the space between the crystals, to the Receive Crystal. If the space is

filled with air, gas, or vacuum, the Receive Crystal does not detect the sound pulse. However, if the space is filled with

liquid, any liquid, the pulse is detected by the Receive Crystal, and the switch output changes.

INSTALLATION

Unpack the switch carefully. Inspect all units for damage. Report any damage to carrier immediately. Check the

contents against the packing slip and purchase order.

Kenco’s Ultrasonic Switches are manufactured to the highest quality standards. These switches use electronic

components that can be damaged by static electricity. Make sure that you are properly grounded before starting

installation. Insure that all electrical connections are properly made, and that there are no “floating” connections.
