A non-contact level sensing technology is an
ultrasonic level transmitter. Determine the solid material and liquid levels. The ultrasonic level transmitter works in the same way as the radar level sensor. However, the ultrasonic level transmitter is less expensive. Sino-Inst manufactures ultrasonic level transmitters that are compact, split, explosion-proof, and intrinsically secure. Measuring ranges of up to 30 meters. Used to calculate tank levels, river water levels, and so on.
Characteristics
The viscosity and density of the liquid have less of an impact on non-contact measurement. 2.
There are optional ranges of 5 meters, 10 meters, 15 meters, 20 meters, and 30 meters. 3.
Degree of protection: probe IP68, view IP65.
In this case, optional explosion-proof and isolated explosion-proof are available.
Optional anti-corrosion substance 6.
Optional relays range from 0 to 4.
Working Theory of an Ultrasonic Level Transmitter
An ultrasonic level transmitter's structure is as follows:
The piezoelectric crystal is the main component of the ultrasonic sensor. It has the ability to not only transmit but also receive ultrasonic waves.
Ultrasound probes with low power are usually used for research. Many of its friends have various structures, which can be classified as straight probe (longitudinal wave), oblique probe (transverse wave), elastic wave probe (surface wave), lamb wave probe (lamb wave), double probe (one probe reflection, one probe receiving), and so on.
The ultrasonic laser sensor is built around a piezoelectric chip housed in a plastic or alloy metal shell. The material used to make the wafer can vary from these. The chip's height, diameter, and thickness are also different. As a result, the output of each sensor varies, and we must anticipate its performance during use.
The ultrasonic level transmitter operates on the following principles:
The surface of the measured level (material) is reflected by an ultrasonic transducer (probe) that emits high-frequency pulse sound waves. The transducer receives the reflected echo and converts it into an electrical signal. The sound wave's propagation time is proportional to the distance between the sound wave and the object's surface.
The formula S=CT/2 expresses the relationship between the sound wave propagation distance S, the sound speed C, and the sound transmission time T.
The probe emits ultrasonic waves that are absorbed by the liquid surface.
The probe component has been re-acquired. The distance between the probe and the liquid (object) surface is proportional to the ultrasonic wave's elapsed time:
CT2 = HB
Distance [m] = time speed of sound divided by distance [m]
Sound velocity temperature compensation formula:
Sound velocity in the environment = 331.5 + 0.6 temperature
