Why Choose the Carlo Gavazzi VP03E Infrared Level Sensor?
The Carlo Gavazzi VP03E is a compact photoelectric liquid level sensor designed for point-level detection in tanks, containers and industrial process equipment. It uses unmodulated infrared light to detect liquid at the sensing tip, providing electronic level detection without a conventional mechanical float.
Part of the Carlo Gavazzi VP series, the VP03E combines its infrared transmitter, receiver and built-in amplifier within a self-contained threaded housing. It provides an NPN normally closed (NC) output and operates from a wide 10–40 V DC supply, making it suitable for integration with compatible PLCs, relays and industrial control systems.
The VP03E features a high-chemical-resistance Polyamide 12 housing, a pre-wired 2 m PVC cable and IP67 protection. Its compact 3/8-inch threaded construction is designed for mounting directly into a container wall, providing a robust solution for industrial liquid-level monitoring.

Reliable Infrared Liquid Level Detection
The Carlo Gavazzi VP03E uses an optical principle to determine whether liquid is present at its sensing tip. Its infrared transmitter and receiver are incorporated into the sensor housing, and the change in optical conditions when the liquid reaches the probe is converted by the built-in amplifier into an electrical switching signal.
With its NPN NC output, 10–40 V DC supply range and chemically resistant Polyamide 12 construction, the VP03E provides a straightforward point-level sensing solution for automated filling, emptying, alarm and process-monitoring systems.
Typical Applications
- Industrial tank and container level detection.
- High- and low-level monitoring.
- Automatic filling and emptying systems.
- Pump and valve control applications.
- Industrial process equipment.
- Liquid handling and storage systems.
- Packaging and production machinery.
- OEM industrial automation equipment.
