DFRobot URM14-RS485 Precision Ultrasonic Sensor (200KHz) Offers a high-frequency precision Uses the RS485 interface Comes with a flexible temperature compensation function Measuring Frequency: 30 HZ Operating Temperature: -20 ~＋80 °C The DFRobot URM14-RS485 Precision Ultrasonic Sensor (200KHz) is a high-frequency precision ultrasonic sensor for industrial use. The sensor measurement and signal processing unit is completely encapsulated in an M18 metal shell and its tail is designed with an aviation connector plug. The sensor uses the RS485 interface that follows the standard Modbus-RTU communication protocol, which assures its compatibility with PLC industrial personal computer. Furthermore, the adoption of higher ultrasonic acoustic frequency and more precision signal processing circuit gives this URM14 sensor mm-grade accuracy and up to1.5 m reliable measuring range. The only 12° measuring angle makes the sensor able to present the directional measurement characteristic similar to laser ranging sensors.
