## Description

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 to1.5m reliable measuring range. The only 12° measuring angle makes the sensor able to present the directional measurement characteristic similar to laser ranging sensors.With the advanced auto noise detection function integrated, the URM14 sensor can detect noise in real-time and adjust its parameter based on the noise level. In addition, it comes with a flexible temperature compensation function that allows users to use the sensor built-in temperature compensation or external temperature compensation according to their needs, which makes it applicable to various complicated application scenarios.Board OverviewSPECIFICATION Operating Voltage: DC 7-15V Max Instantaneous Current: 350mA Effective Measuring Range: 100-1500mm Distance Resolution: 0.1mm Measuring Accuracy: 1mm Distance Error: ±0.1% Temperature Resolution: 0.1℃ Temperature Error: ±1℃ Measuring Frequency: 30HZ Operating Temperature: -20℃～＋80℃ Sensor Acoustic Frequency: 200KHz±4% Directional Angle: 12°±2°(-6dB) Protection Grade: IP65 Communication Interface: RS485 DOCUMENTSProduct wiki
