What is the ENDRESS+HAUSER PROSONIC FMU 860 Ultrasonic Transmitter?
The ENDRESS+HAUSER PROSONIC FMU 860 Ultrasonic Transmitter is a state-of-the-art non-contact level measurement device widely used in industrial and marine environments. This device uses ultrasonic sound waves to precisely measure the level of liquids, slurries, and bulk solids without making physical contact. Manufactured by Endress+Hauser, a global leader in process automation, the FMU860 ensures reliability, safety, and efficiency in even the harshest industrial conditions.
The device works by sending ultrasonic pulses which bounce off the surface of the material to be measured. The time it takes for the echo to bounce back is then used to determine the distance, and hence the level, of the monitored substance. This is perfect where contact sensors may fail because of contamination, corrosion, or wear.
Key Features
Following are the salient features that render FMU 860 a reliable option for level measurement:
Non-Contact Measurement: Avoids contamination and long life by not coming into direct contact with the medium.
High Accuracy: Provides accurate measurements with impeccable repeatability, even under dusty or turbulent situations.
Rugged Construction: Made for industrial and maritime application, with water, dust, and chemical resistance.
Wide Measuring Range: Capable of handling various tank sizes and silo depths with long-range measurement capability.
Integrated Display and Configuration: Comes with easy-to-read digital display and push-button programming interface.
Two-Wire Technology: Simplifies wiring and installation by transmitting power and signal on the same line.
Self-Diagnostics: Offers built-in error detection and status alerts for proactive maintenance.
