Why Choose the Carlo Gavazzi VP04EM Infrared Level Sensor?
The Carlo Gavazzi VP04EM is a compact photoelectric liquid level sensor designed for point-level detection in tanks, containers and industrial process equipment. It uses infrared light to detect the presence or absence of liquid at the sensing tip, providing reliable electronic level detection without a conventional mechanical float.
Part of the Carlo Gavazzi VP series, the VP04EM combines the optical transmitter, receiver and amplifier within a self-contained cylindrical threaded housing. It provides an NPN normally open (NO) 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 VP04EM features a high-chemical-resistance Polyamide 12 housing, a pre-wired 2 m PVC cable and IP67 protection. Its compact 3/8-inch × 74 mm construction, broad operating temperature range and robust pressure capability make it a practical choice for industrial liquid-level monitoring.

Reliable Infrared Liquid Level Detection
The Carlo Gavazzi VP04EM detects liquid by monitoring the behaviour of infrared light at its sensing tip. The transmitter and receiver are incorporated within the same sensor housing, and the built-in amplifier converts changes in optical conditions caused by the presence or absence of liquid into an electrical switching signal.
With its NPN NO output, 10–40 V DC supply range and chemically resistant Polyamide 12 construction, the VP04EM provides a compact solution for automated filling, emptying, alarm and process-monitoring applications where dependable point-level detection is required.
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.
