Why Choose the Carlo Gavazzi VP01EM Infrared Liquid Level Sensor?
The Carlo Gavazzi VP01EM is a compact and reliable photoelectric liquid level sensor designed for detecting the presence or absence of liquids in tanks, vessels and industrial process equipment. As part of the Carlo Gavazzi VP series, it uses infrared optical sensing to provide contact-free electrical detection without an electrical or thermal connection between the liquid and the sensor's electrical circuit.
The VP01EM combines an infrared emitter and receiver with a built-in amplifier in a chemically resistant polysulphone housing. Its optical sensing principle detects the change in internal light reflection that occurs when the sensor tip is immersed in liquid, providing dependable level switching without moving mechanical components.
With a 10–40 V DC supply, NPN normally closed (NC) output, 2 m PVC cable and IP67 protection rating, the VP01EM is well suited to industrial liquid monitoring. Its threaded cylindrical construction allows direct mounting through the wall of a tank or vessel, while the polysulphone body provides high chemical resistance for demanding process applications.

Reliable Infrared Level Detection for Industrial Liquids
The Carlo Gavazzi VP01EM detects liquid using an optical sensing tip and infrared light. When the tip is surrounded by air, infrared light is internally reflected within the sensor. Immersion in liquid changes the optical conditions at the tip, allowing the integrated electronics to detect the change and switch the output accordingly.
This solid-state sensing method eliminates floats and other moving mechanical components while keeping the liquid electrically isolated from the sensor circuitry. Combined with its chemically resistant polysulphone construction, the VP01EM provides a practical solution for point-level monitoring in industrial tanks, process equipment and automated liquid-handling systems.
Typical Applications
- Industrial liquid-level detection.
- Tank and vessel level monitoring.
- High- and low-level alarm systems.
- Process liquid monitoring and control.
- Pump and filling-system automation.
- Water and wastewater equipment.
- Food and beverage process equipment with compatible liquids.
- Industrial machine and process automation.
