Ultrasonic Level Instrument LU90
The LU90 transmitter is an electronic equipment based on the
transmission of ultrasonic waves to measure the distance to a
liquid or solid in a vessel.
The electronic circuit offers the following features:
•
Emission and reception circuits for the ultrasonic
signals, and microprocessor treatment.
•
Alarm outputs with programmable hysteresis level.
•
Programmable current output proportional to the
distance or level.
•
HART TM protocol compatibility (model LU90H).
