Why Choose the Carlo Gavazzi VPB2MNA-1 Photoelectric Liquid Level Sensor?

The Carlo Gavazzi VPB2MNA-1 is a robust photoelectric liquid level sensor designed for reliable point-level detection in tanks, vessels and industrial process equipment. Part of the Carlo Gavazzi VP series, it uses modulated infrared light to detect the presence or absence of liquid without relying on floats or other moving mechanical sensing components.

The VPB2MNA-1 combines a durable nickel-plated brass housing with a glass sensing interface, providing high chemical resistance for compatible liquids. Its transmitter, receiver and amplifier are integrated within a cylindrical threaded body, creating a self-contained optical sensing solution for direct mounting into the wall of a suitable tank or vessel.

Designed for a 10–40 V DC supply, the VPB2MNA-1 features an NPN change-over output providing NO and NC functions with a load current below 200 mA. Electrical connection is provided by an M12 connector, while its IP67 protection rating supports reliable operation in demanding industrial liquid-level applications.

Reliable Photoelectric Liquid Level Detection

The VPB2MNA-1 uses modulated infrared light to detect changes at its optical sensing interface when liquid reaches or leaves the sensing point. The transmitter, receiver and amplifier are incorporated into the sensor body, providing self-contained point-level detection without a mechanical float or moving sensing mechanism.

The Carlo Gavazzi VPB2MNA-1 combines this optical sensing principle with an NPN NO+NC change-over output, allowing both normally open and normally closed switching functions to be used according to the control application. Its nickel-plated brass and glass construction, 10–40 V DC supply, M12 connection and IP67 protection make it well suited to industrial tanks, vessels and automated process systems.

Typical Applications

• Industrial liquid level detection.
• High-level and low-level tank monitoring.
• Overflow and liquid presence detection.
• Process vessels and liquid storage tanks.
• Industrial water and fluid handling systems.
• Automated machinery and process-control equipment.
