Why Choose the Carlo Gavazzi VP02-110TB Infrared Liquid Level Sensor?

The Carlo Gavazzi VP02-110TB is a compact and reliable infrared optical liquid level sensor designed for point-level detection in tanks, vessels and industrial process equipment. As part of the Carlo Gavazzi VP series, it uses unmodulated infrared light to detect the presence or absence of liquid without requiring an electrical or thermal connection between the liquid and the sensor's electrical circuit.

The VP02-110TB incorporates the infrared transmitter, receiver and amplifier within a chemically resistant polysulphone housing. A GaAs infrared-emitting diode and optical prism provide solid-state liquid detection without floats or other moving mechanical sensing components, making the sensor well suited to reliable industrial level-monitoring applications.

Designed for a 100–121 V AC, 45–60 Hz supply, the VP02-110TB features a normally open (NO) SCR make-switching output with a rated operational current of 10–100 mA. A 2 m cable, 3/8-inch PT threaded mounting and IP67 protection rating support straightforward integration into tanks, containers and automated process equipment.

Reliable Infrared Liquid Level Detection

Optical level sensors detect liquid through changes in the behaviour of infrared light at the sensing prism. When the prism is surrounded by air, infrared light is internally reflected towards the receiver; when liquid covers the sensing surface, the optical conditions change and the sensor switches its output. This provides dependable point-level detection without floats, mechanical linkages or direct electrical contact with the monitored liquid.

The Carlo Gavazzi VP02-110TB combines this optical principle with an integrated amplifier and normally open SCR output. Its compact threaded construction and chemically resistant polysulphone housing make it suitable for liquid presence detection, high-level monitoring, low-level monitoring and automated process-control applications.

Typical Applications

• Industrial liquid level detection.
• High-level and low-level tank monitoring.
• Overflow detection and alarm systems.
• Process vessels and liquid storage tanks.
• Industrial water and fluid handling equipment.
• Automated machinery and process-control systems.
