CJ-2000 Ultrasonic Level Gauge

integrated split-type Liquid level difference gauge

Overview

CJ-2000Ultrasonic material/Level transmitterIt absorbs the advantages of various similar products at home and abroad,Using energy-saving components to ensure that the operating current of the entire machine is less than3.5mACan work reliably in9－32VWithin the DC power supply voltage. Highly intelligent software design, capable of setting the final and starting values of current and adjusting the output current through the keyboard. Reliable, pollution-free, and stable performance,Due to its low cost and other characteristics, it can be widely applied in various fields related to level, material level, and liquid level measurement and control.

working principle

The probe emits ultrasonic waves, which are then reflected by the liquid surface

Re receive, probe to liquid(thing)The distance between the surface and the time it takes for ultrasonic waves to pass through are proportional:

hb = namely

distance[m] =Time x speed of sound/2 [m]

Temperature compensation formula for sound velocity:Environmental sound velocity= 331.5 + 0.6X Temperature
