Why Choose the Carlo Gavazzi VP04EPM Infrared Liquid Level Sensor?

The Carlo Gavazzi VP04EPM is a compact and reliable infrared optical liquid level sensor designed for point-level detection in tanks, vessels and industrial process equipment. As part of the Carlo Gavazzi VP series, it uses unmodulated infrared light to detect the presence or absence of liquid without relying on floats or other moving mechanical sensing components.

The VP04EPM incorporates its optical transmitter, receiver and amplifier within a chemically resistant Polyamide 12 housing. Its cylindrical threaded construction allows direct installation into a suitable tank or container wall, while the infrared sensing principle provides dependable detection of both conductive and non-conductive liquids compatible with the sensor material.

Designed for a 10–40 V DC supply, the VP04EPM features a PNP normally open (NO) transistor output with a load current below 200 mA. It is supplied with a 2 m PVC cable and provides an IP67 protection rating, making it well suited to industrial liquid-level monitoring and automated process-control applications.

Reliable Infrared Liquid Level Detection

Optical level sensors detect liquids by monitoring changes in infrared light at the sensing interface. When liquid reaches the sensing point, the optical conditions change and the integrated electronics switch the output. This solid-state sensing principle enables dependable point-level monitoring without floats, mechanical linkages or direct electrical contact between the liquid and the sensor's electrical circuit.

The Carlo Gavazzi VP04EPM combines this optical sensing principle with a PNP normally open output and wide 10–40 V DC supply range. Its Polyamide 12 housing offers high chemical resistance, while the IP67 construction and high ambient-light immunity make it suitable for integration into industrial tanks, process equipment and automated machinery.

Typical Applications

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