Why Choose the Carlo Gavazzi VP02EP Infrared Liquid Level Sensor?

The Carlo Gavazzi VP02EP is a compact infrared photoelectric liquid level sensor designed for point-level detection in tanks, vessels and industrial liquid-handling equipment. Part of the Carlo Gavazzi VP series, it uses an optical sensing principle to detect when liquid reaches the probe tip without relying on floats or other moving mechanical components.

The VP02EP incorporates an infrared emitter, receiver and switching electronics within a robust sensor assembly. When the optical tip is surrounded by air, infrared light follows a different internal reflection path than when the tip is immersed in liquid, allowing the sensor to detect the change in medium and switch its transistor output.

With a 10–40 V DC supply and PNP normally open (NO) output, the VP02EP is designed for straightforward integration with PLCs, relays and industrial control equipment. Its solid-state sensing method provides dependable point-level monitoring for filling, emptying, alarm and process-control applications involving compatible liquids.

Reliable Solid-State Liquid Level Detection

The Carlo Gavazzi VP02EP determines liquid presence by monitoring infrared light within its optical sensing tip. When liquid contacts the tip, the difference between the refractive properties of air and the liquid changes the amount of light reaching the receiver, allowing the sensor electronics to switch the PNP output.

Because the sensing principle does not require a mechanically operated float, the VP02EP is particularly useful where compact, repeatable point-level detection is required. It can form part of an automated control system for monitoring liquid presence, controlling pumps or valves, or signalling high and low liquid-level conditions.
