Compact and analogue the UM 18 ultrasonic sensor
Waldkirch, April 2005 The UM 18 ultrasonic sensor is now also available as an analogue output version. As a result, the device can now be used for continuously detecting and transmitting distance or height changes over scanning distances between 30 mm and 250 mm. In addition the sensor, in its short and robust M18 fine-thread housing, offers one or two switching outputs whose switching threshold can be programmed by teach-in or via a control cable.

The UM 18 offers analogue output options of either 4 - 20 mA or 0 - 10 V DC. While the Standard version offers a single switching output, the UM 18 High-end has two switching outputs necessary for min-max regulation during level detection or the regulation of slack in addition to two function LEDs. Integrated temperature compensation ensures that detection accuracy and reliability are unaffected by any changes in the ambient temperature.

The analogue UM 18 is used, for example, for checking liquid levels even in harsh environments, measuring filling levels in cartridges and dispensing machines, detecting transparent objects such as foils, or monitoring slack in web products.
