Carlo Gavazzi’s UA Series ultrasonic sensors are designed for both distance measurement and object detection in tough environments. The range consists of both M18 and M30 housings. Discrete output types are available for presence and absence detection, and are ideally suited for detecting objects,such as transparent objects, that cannot be reliably detected by other sensors. | Carlo Gavazzi s UA Series ultrasonic sensors are designed for both distance measurement and object detection in tough environments. The range consists of both M18 and M30 housings. Discrete output types are available for presence and absence detection and are ideally suited for detecting objects such as transparent objects that cannot be reliably detected by other sensors. Analogue output types are available on our sensors for applications requiring a measurement of the target object such as detecting the level of fluid in a tank. The analogue models have your choice of 0-10 VDC or 4-20 mA outputs. Our more advanced ultrasonic sensor models incorporate teach functions which allow the set-points to be configured with the push of a button and via Windows-based software for applications where greater control of sensor parameters and variables is required. The Windows version also allows for settings to be saved and downloaded to multiple devices. FAQ Library Cross Reference Product Brochure If you already know the series of sensor you can click the list below to view the datasheet. Q. Please explain the difference between diffuse and through-scan. Diffuse mode is the standard mode of operation. In this mode objects travelling in any direction into the operating range of the sound cone will cause the sensor to switch output states. The Thru-scan mode uses a reflector located in the preset operating range. This can be any good reflective background such as a wall. The operating range is adjusted for the reflector. The pulses are bounced off the reflector and the echo pulses are returned to the sensor. When a target blocks the echo pulses the output is activated. Q. Where can I get instruction manuals for Carlo Gavazzi ultrasonic sensors Instruction manuals for all Carlo Gavazzi ultrasonic sensors are available online.
