Sensors with analog evaluation are required for reliable level monitoring of a tank. An ideal solution for this task is the UT309023 ultrasonic sensor from ipf electronic in combination with the versatile BA050100 analog converter.
For this purpose, the UT309023 ultrasonic sensor is mounted in the lid area of a silo tank so that the sound cone generated by the sound transducer is aligned downward on the material to be detected. From the time taken for the ultrasonic waves to travel from the sensor to the material and back to the device, the sensor calculates the exact distance and outputs this value as an analog current or voltage signal. Via the teach mode or the integrated IO-Link interface, the measuring range of 600-6,000mm can be perfectly adapted to the silo tank.
