Ultrasonic Level Transmitter- Series UL
Continuous, Noncontact, 4 to 20 mA Output
Series UL Ultrasonic Level Transmitters provide continuous noncontact sensing for level control of liquids or slurries. The sensor emits an ultrasonic pulse which is reflected back to the sensor at the liquid/air interface. The distance traveled by the pulse is calculated and converted into a 4-20 mA output signal. Internal microprocessor performs self diagnostics to indicate possible operating problems such as out-of-range or loss of echo. Failsafe feature can be set to deliver a 3 or 21 mA output in the event the echo is lost.
