Why Choose the Carlo Gavazzi VP03EPAX ATEX Optical Level Sensor?

The Carlo Gavazzi VP03EPAX is an ATEX-certified infrared optical liquid level sensor designed for dependable point-level detection in tanks, containers and industrial process equipment. Part of the Carlo Gavazzi VP series, this sensor combines an unmodulated infrared light source, receiver and built-in amplifier within a compact solid-plastic housing designed for direct mounting into a container wall.

Designed specifically for hazardous-area applications, the VP03EPAX is suitable for ATEX Zone 1 installations where an explosive gas atmosphere may occur during normal operation. The sensor uses a Polyamide 12 housing with resistance to various solvents and provides optical liquid detection without an electrical or thermal connection between the liquid and the electrical circuit.

The VP03EPAX provides a PNP normally closed (NC) transistor output and operates from a 10–16.8 V DC rated supply. It features a 2 m PVC cable, IP67 ingress protection, yellow LED output indication and a 3/8-inch PT threaded connection, providing a robust solution for liquid level monitoring in hazardous industrial environments.

Reliable Liquid Level Detection for Hazardous Areas

The Carlo Gavazzi VP03EPAX detects liquid using an infrared transmitter and receiver integrated into the sensing assembly. Changes in the optical characteristics at the sensing tip allow the sensor to determine whether liquid is present, providing reliable point-level switching without floats, electrodes or other mechanically moving sensing components.

Its ATEX-rated construction makes the VP03EPAX particularly suitable for hazardous process environments. The combination of a chemically resistant Polyamide 12 body, IP67 protection, intrinsically safe ATEX classification and compact threaded mounting provides a practical level monitoring solution for industrial tanks and fluid-handling equipment where potentially explosive atmospheres may be present.

Typical Applications

• Hazardous-area liquid level detection.
• ATEX Zone 1 tanks and process vessels.
• Industrial chemical and solvent handling systems.
• Process automation and fluid monitoring equipment.
• Machine reservoirs and liquid storage containers.
• Industrial plant and OEM process machinery.
