Focusing on a full-industry-chain strategy for mid-to-high-end environmental monitoring instruments and industrial process instruments
The working principle of ultrasonic level gauge is that the transducer (probe) emits a high-frequency ultrasonic pulse that is reflected back when it encounters the surface of the measured medium, and is partially received by a transducer and converted into an electrical signal. The ultrasonic pulse propagates at the speed of sound waves, and the time interval from transmission to reception of the ultrasonic pulse is directly proportional to the distance on the surface of the transducer.

The Pt series diffusion silicon pressure transmitter is a new generation of pressure transmitter produced by using imported chips, after careful structural design, signal processing and assembly, and testing in accordance with national standards and enterprise standards. The basic principle is to use the piezoresistive effect and micromachining technology of semiconductors, use lithography, diffusion and other semiconductor processes to make a Wheatstone bridge, form a sensitive diaphragm, when under the action of external force, produce microstrain, resistivity changes, so that the resistance of the bridge arm changes (one pair becomes bigger and one pair becomes smaller) and then excites the voltage signal output, through computer temperature compensation, laser resistance regulation, signal amplification and other processing methods and strict assembly testing, calibration and other processes, to produce a pressure transmitter with standard output signal.
