Why Choose the Carlo Gavazzi UA18CLD15AG Ultrasonic Sensor?

The Carlo Gavazzi UA18CLD15AG is a compact and reliable M18 diffuse-reflective ultrasonic proximity sensor with a 4–20 mA analogue output, designed for continuous non-contact distance and level measurement in industrial automation systems. As part of the Carlo Gavazzi UA18CL series, it provides dependable detection of a wide range of materials without relying on their colour, transparency or surface appearance.

The UA18CLD15AG provides an adjustable 200–1500 mm sensing distance and converts the measured target position into a standard industrial 4–20 mA current signal. This makes it suitable for connection to PLC analogue inputs, process controllers and monitoring equipment where proportional distance or level information is required.

With an 18–30 V DC operating supply, robust plastic M18 housing and IP67 protection rating, the UA18CLD15AG is engineered for industrial machinery and factory automation environments. The sensor is supplied with an integral 2 m cable, providing a straightforward hard-wired connection within control and automation systems.

Reliable Ultrasonic Measurement for Industrial Automation

Ultrasonic sensors determine distance by transmitting high-frequency sound towards a target and evaluating the returning echo. Because this measurement principle does not depend on visible light, ultrasonic sensing is well suited to applications involving transparent, reflective, dark or visually inconsistent materials that may be difficult to detect using conventional optical sensors.

The UA18CLD15AG converts measured distance into a standard 4–20 mA analogue signal, enabling continuous measurement data to be processed by PLCs and industrial controllers. Its extended sensing range makes it particularly useful for level monitoring, object positioning and distance measurement where physical contact with the target is undesirable.

Typical Applications

• Continuous distance measurement in automated machinery.
• Tank, hopper and container level monitoring.
• Object positioning and presence measurement.
• Conveyor and material handling systems.
• Packaging and production machinery.
• PLC-based analogue measurement and process monitoring.
• Machine building and factory automation systems.
