ULT 3120 - Ultrasonic level transmitter - FLP

ULT 3120 is a non-contact type continuous level measuring transmitter which is used to measure the levels of liquids and solids. It operates at a frequency 20~70KHz, with a beam angle of 5° to 12°. It has perfect level monitoring, data transmission and man-machine communication.

Free setting of upper and lower limits and online output regulation, on-site indication, optional analog, switching value and RS 485 output.

KEY HIGHLIGHTS

Non-contact measurement
Automatic detection of on-site electrical interference
Non-invasive and strong anti-interference
Automatic temperature compensation.
Support 4-20 mA current simulation
