Why Choose the Carlo Gavazzi VPA2MNA-1 Photoelectric Liquid Level Sensor?

The Carlo Gavazzi VPA2MNA-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 VPA2MNA-1 combines an AISI 303 stainless steel housing with a glass sensing interface, providing a durable construction with high chemical resistance. The sensor incorporates the optical transmitter, receiver and amplifier within a cylindrical threaded body designed for direct installation into the wall of a suitable tank or vessel.

Designed for a 10–40 V DC supply, the VPA2MNA-1 features an NPN change-over output providing NO and NC functions. Electrical connection is through an M12 connector rather than a permanently attached cable, allowing compatible connection leads to be selected to suit the installation. The sensor also provides IP67 protection for demanding industrial liquid-level applications.

Reliable Photoelectric Liquid Level Detection

The VPA2MNA-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 VPA2MNA-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 stainless steel and glass construction, wide 10–40 V DC supply range and convenient M12 connection make it particularly suitable for 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.
