Ultrasonic Liquid (Object) Level Sensor-LF650

Product introduction

LF650 series ultrasonic liquid (material) sensor mounted on the upper part of the container, under the control of an electronic unit, the probe sends a beam of ultrasonic pulse to the measured object. The sound wave is reflected from the surface of the object, and part of the reflected echo is picked up by the probe and converted into an electrical signal. The time from ultrasonic transmission to rereception is proportional to the distance from the probe to the measured object. An electronic unit detects the event and calculates the measured distance based on the known speed of sound. The potential value of the liquid can be obtained by subtraction operation.
It can be connected to the display table or various DCS systems through 4~20mA to provide real-time liquid level data for the automatic operation of industry.

-liquid level accuracy of ±0.25%, can resist various interference waves.
-Non-contact type, not with direct contact with the liquid, so low failure rate.
-All input and output lines have the protection function of lightning protection and short circuit protection.
