Ultrasonic position switch

External ultrasonic switch-type sensing for piston-position detection

Ultrasonic Position Switch

Schwerll Industrial Fluid Power Equipment - Ultrasonic Position Switch

Product category: Fluid detection component

SKU: SCH-1049

SCHWERLL Ultrasonic Level Detection Sensor:

The UPS ultrasonic sensor is an external switch-type sensor used to measure piston position. It is mounted on the outer wall of an accumulator or hydraulic cylinder using mounting bases, clamps, and other accessories. During operation, the ultrasonic switch continuously emits ultrasonic signals and receives the reflected echoes. When the liquid level is detected, the switch’s output voltage changes, generating a discrete switching signal.

UPS ultrasonic switches are highly sensitive to the viscosity and temperature of the liquid being detected, as well as to the wall thickness of accumulator or cylinder barrels. When selecting a model, it is essential to verify these parameters and choose an appropriately matched version.

Sensing and selection

The UPS ultrasonic position switch is mounted on the outer wall of an accumulator or hydraulic cylinder. It emits ultrasonic signals and receives reflected echoes to detect piston position and liquid level. Detection changes the switch output voltage and generates a discrete switching signal.

Confirm liquid viscosity, liquid temperature and barrel wall thickness when selecting the appropriate version. Confirm the mounting arrangement and accessories for the supplied configuration.

Frequently Asked Questions

What is the SCHWERLL Ultrasonic Position Switch used for?

The SCHWERLL UPS ultrasonic sensor is an external switch-type sensor used to detect piston position. It is mounted on the outer wall of an accumulator or hydraulic cylinder using suitable mounting bases, clamps or related accessories.

How does the UPS ultrasonic switch detect position?

During operation, the switch emits ultrasonic signals and receives reflected echoes. When the liquid level is detected, the switch output voltage changes and generates a discrete switching signal.

What operating conditions should be confirmed when selecting a UPS ultrasonic switch?

Selection depends on the viscosity and temperature of the liquid being detected and on the wall thickness of the accumulator or hydraulic-cylinder barrel. These parameters should be confirmed so that the appropriate switch version can be selected.
