URM15 - 75KHZ Ultrasonic Sensor (30~500cm, RS485)

The DFRobot URM15 is an ultrasonic ranging sensor that excels in its precision with a measuring range from 30cm to 500cm, tested on flat surfaces. Its robust design includes an IP65 waterproof probe, making it suitable for outdoor environments. Integrating smoothly with industrial machinery, this sensor utilizes the RS485 interface, which conforms to the Modbus-RTU protocol for steadfast data transmission. This ensures accurate and reliable readings essential for process automation and monitoring systems.

Among its features, the URM15 offers a sophisticated temperature compensation function, allowing users to choose between external or onboard compensation. This capability is crucial in delivering consistent performance irrespective of the ambient temperature changes. With a 75KHz ultrasonic transducer and a 40mm diameter, the sensor demonstrates a narrow measuring angle combined with high sensitivity, making it ideal for applications requiring detailed and precise distance assessments.

Utilizing the URM15 in a wide range of industrial settings illustrates its adaptability, from monitoring fluid levels to controlling machinery functions. The revisable slave addresses and serial parameters facilitate seamless integration into existing systems, enhancing operational efficiency without the need for extensive recalibration. This level of customization ensures that the URM15 can meet the demands of complex industrial tasks with ease.
