High Accuracy Proximity Sensor High Accuracy Sensor for Process Detection Solution Proximity sensor is one of the application of ultrasonic sensor. When the distance between measured object and sensor changes, the sensor can detect the distance and output switching signal in one or several specific distance, then achieve the switch function of equipment. It is mainly applied for industrial automation and water treatment • Compact structure ensures long lifespan e High accuracy, anti electrical magnetic interference o Liquid level control of coffee maker Liquid level control of water purifier
