APG - Model DST - Mid Range Pump Control Ultrasonic Level Sensor - Datasheet

The DST series ultrasonic sensors are designed to be used in conjunction with a DCR controller to give you a simplified, stand-alone system. The transmit and receive circuit is built into the sensor and digitally communicates the detected distance to the DCR controller. This allows the sensor to be separated from the DCR controller by up to 2000 feet with no signal loss. With several sensors to choose from, there are plenty of options for your application needs.
