This sensor is a Vibrating Level Switch which is used to detect the presence or absence of materials inside industrial tanks. This equipment is used in various industries to control the level of liquids, powders, and granular materials and helps to prevent the tank from overflowing or the pump from running dry.

How it works

This sensor has a vibrating metal fork that vibrates continuously:

• In the normal state (in air), the fork vibrates freely.
• By contact with liquid or solid materials such as powder, its vibration is reduced.
• The sensor detects this vibration change and sends a control output.

Applications

• Water and liquid level detection
• Oil and chemical tanks
• Cement, powder and granule silos
• Prevention of tank overflow
• Protecting the pump from running dry

Output type

• Digital output ON/OFF
• Output type: PNP
• In the activation state, it sends the output +24V.

Technical specifications

• Working voltage: 13 to 30 V DC
• Pressure tolerance: up to 40 bar
• Working temperature range: -40 to +150 degrees Celsius
• Made: Pepperl+Fuchs, Germany

Summary

• Industrial level sensor with high precision
• Suitable for liquids, powders and granular materials
• With PNP digital output
• Simple and reliable operation based on the change of vibration of the sensor fork.
