Why Choose the Carlo Gavazzi VP23EPM Infrared Liquid Level Sensor?

The Carlo Gavazzi VP23EPM is a compact infrared photoelectric liquid level sensor designed for reliable 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 VP23EPM incorporates an infrared emitter, receiver and electronic amplifier within a self-contained probe. When the sensing tip changes from air to liquid, the optical conditions and internal infrared reflection change, allowing the electronics to detect the liquid and switch the sensor output.

Featuring a 10–40 V DC supply and PNP normally closed (NC) transistor output, the VP23EPM is designed for straightforward integration with compatible PLCs and industrial control systems. Its solid-state sensing principle makes it well suited to high-level, low-level, filling, emptying and liquid-presence monitoring applications.

Reliable Solid-State Liquid Level Detection

The Carlo Gavazzi VP23EPM detects liquid by monitoring infrared light within its optical sensing tip. When the tip is exposed to air, light is internally reflected differently than when the tip is immersed in liquid. The integrated receiver detects this optical change and the sensor electronics switch the PNP output accordingly.

This solid-state operating principle avoids the mechanical wear associated with conventional float switches and provides a compact solution for point-level monitoring. The VP23EPM can be integrated into automated systems to control pumps and valves or provide high-level, low-level and liquid-presence signals.
