Why Choose the Carlo Gavazzi VP24EM Infrared Liquid Level Sensor?
The Carlo Gavazzi VP24EM 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 infrared optical technology to detect the presence of liquid at the sensing tip without relying on floats or other moving mechanical components.
The VP24EM incorporates an infrared emitter, receiver and electronic amplifier within a self-contained sensing assembly. When liquid reaches the optical tip, the change in refractive conditions alters the internal reflection of infrared light, allowing the integrated electronics to detect the level condition and switch the output.
With a 10–40 V DC supply and NPN normally open (NO) transistor output, the VP24EM is designed for straightforward integration with compatible PLCs, relays and industrial control systems. Its solid-state operating principle provides dependable point-level sensing for filling, emptying, alarm and process-control applications involving compatible liquids.

Reliable Solid-State Liquid Level Detection
The Carlo Gavazzi VP24EM determines liquid presence by monitoring infrared light within its optical sensing tip. The difference in refractive properties between air and liquid changes the amount of internally reflected light reaching the receiver, allowing the integrated electronics to switch the NPN output when liquid reaches the sensor.
This optical operating principle avoids the moving components associated with conventional float switches. The VP24EM can therefore provide compact and repeatable point-level monitoring as part of automated systems controlling pumps, valves, filling processes and liquid-level alarms.
