Why Choose the Carlo Gavazzi VP02E Infrared Liquid Level Sensor?
The Carlo Gavazzi VP02E is a compact photoelectric liquid level sensor designed for reliable point-level detection in tanks, containers and industrial fluid-handling systems. Using unmodulated infrared light, the sensor detects liquid directly at its optical sensing tip without requiring floats or other moving mechanical components.
Designed for a 10–40 VDC power supply, the VP02E provides an NPN normally open (NO) transistor output. The output switches on when the sensor detects liquid, making the device suitable for presence detection, level monitoring and automated process-control functions. An integrated amplifier allows the sensor to provide a direct switching output for connection to compatible industrial control equipment.
The VP02E features a chemically resistant polysulphone housing, a 2 m PVC cable and IP67 protection. Its compact 3/8" threaded design measures approximately 74 mm in length and is designed for mounting directly into a tank or container wall, providing a robust solution for industrial liquid-level sensing.

Reliable Infrared Liquid Level Detection
The VP02E uses an infrared transmitter and receiver integrated into the sensing assembly to determine whether liquid is present at the sensor tip. The optical conditions change when the tip comes into contact with liquid, allowing the built-in electronics to switch the NPN output without requiring a mechanical float or direct electrical measurement through the liquid.
Its polysulphone construction provides high chemical resistance, while the 10–40 VDC supply, normally open transistor output and integrated amplifier simplify connection to industrial automation equipment. With IP67 protection and a pressure rating of 10 bar at +60 °C, the VP02E provides a durable point-level sensing solution for demanding fluid-monitoring applications.
Typical Applications
- Industrial tank liquid-level detection.
- Liquid presence and absence monitoring.
- Storage tanks and process vessels.
- Automatic filling and draining systems.
- Pump control and fluid-management systems.
- Industrial machinery with liquid reservoirs.
- Process automation and fluid-handling equipment.
