Ultrasonic Level Transmitter – DU – 12 – D
DU-12-D is a set of a separate transducer part and a controller.
The transducer measures the level using ultrasonic waves, and the controller outputs the screen and relay contact signals so that the user can easily read the level values measured by the transducer which is likely to be installed at a remote location.
DU-12-D supports both analog 4~20mA current and digital RS485 signal outputs. The sensing part (Transducer) is of IP68 waterproof / dustproof grade and is durable. And its built-in temperature sensor enables more precise measurement.
