Integrated type Cable instruction: :
1.Wiring instruction of transducer: interface (3pin, 2.54mm terminal)
Red: transducer +
White: transducer -
Black: shielding
2.Cable Instruction of Temperature Sensor: interface (3pin, 2.0mm terminal)
Red and black are temperature sensor wiring
Ultrasonic Level Gauge Application:
The ultrasonic level meter is used to continuously monitor level channels in the height of liquid media, sludge or suspensions in both open and closed tanks and channels. The gauge generates the level-height information in the form of a signal current 4 to 20mA. The lower and upper limits of the measurement range can be set by potentiometers in the electronic unit of the gauge.
