Why Choose the Carlo Gavazzi VP05EM Optical Liquid Level Sensor?

The Carlo Gavazzi VP05EM is an optical 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 infrared optical sensing to detect the presence or absence of liquid without relying on floats or other moving mechanical sensing components.

The VP05EM incorporates its sensing electronics and amplifier into a compact cylindrical housing designed for mounting directly into a suitable container wall. Its solid-state optical operating principle provides repeatable liquid detection while avoiding direct electrical or thermal connection between the monitored liquid and the sensor's electrical circuit.

Designed for a 10–40 V DC supply, the VP05EM features an NPN normally closed (NC) transistor output and a 2 m cable. Its industrial VP-series construction makes it suitable for liquid presence detection, tank-level monitoring, overflow protection and automated process-control applications.

Reliable Optical Liquid Level Detection

Optical level sensors detect liquids by monitoring changes in the behaviour of infrared light at the sensing interface. When liquid reaches or leaves the sensing point, the optical conditions change and the sensor electronics switch the output. This enables reliable point-level monitoring without a float, mechanical linkage or other moving sensing mechanism.

The Carlo Gavazzi VP05EM combines this optical sensing principle with an NPN normally closed output and a wide 10–40 V DC operating range. It is particularly suited to applications where a compact, self-contained electronic sensor is required to provide a discrete signal indicating the presence or absence of liquid at a defined level.

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 equipment.
• Automated machinery and process-control systems.
