Yushi Instruments is a fast-growing thickness gauge manufacturer in the China. We strive for high-tech thickness measurement technology to solve various thickness measurement problems. UM-4 series is a new generation thickness gauge launched by Yushi Instruments, which greatly improves the performance of the previous ultrasonic thickness gauge, and has better measurement stability and repeatability. It is widely used in the wall thickness measurement of pipelines, pressure vessels and storage tanks in petrochemical, electric power, shipbuilding and manufacturing industries.

● Economical full digital thickness gauge

The full-digital thickness gauge needs to convert the analog ultrasonic signal into a digital signal, then perform arithmetic processing on the digital signal, and finally obtain high-performance thickness measurement capability. The A-scan snapshot function, zero-crossing measurement technology, and high resolution of the UM-4 series are all based on full digital technology.

● Innovative A-scan snapshot function, marks the entry of all-digital era

The A-scansnapshot waveform display function provided by UM-4 series thickness gauge make the ultrasound no longer an invisible and intangible abstract concept. Users can see the ultrasound signal waveform on the screen directly to verify whether the thickness reading is correct, analyze the cause of the problem, Help users find solutions to problems.

● Breakthrough zero-crossing measurement technology

Based on full-digital technology and adopting zero-crossing measurement technology, the thickness measurement value can not be affected by echo strength, material attenuation coefficient, gain and gate height, and has high measurement stability and reliability.

● Through Coating Function

We have already launched UM-1D and UM-2D thickness gauges with penetrating coating technology, which have been recognized and praised by users, and now the UM-4D and UM-4DL have the same function, which is achieved by measuring two continuous bottom echoes of the substrate.

There are more advantages in this mode:

1. Without zero calibration;

2. High stability, the measured value can not be affected by the pressure of the probe, the      thickness of the coupling layer and the dust on the surface of the workpiece;

3. Zero drift.

● More practical features

◆ Gain: high, medium and low three gears adjustable；

◆ Alarm mode: the thickness color changes dynamically when alarming；

◆ Difference/reduction rate: The difference mode displays the change in the difference between the measured thickness and the preset thickness. The reduction rate is to calculate and display the percentage of thickness reduction after the material getting thinner. A typical application is to measure metal materials that have become thinner due to bending;

◆ Maximum/minimum value capture: The current thickness value, minimum thickness value and maximum thickness value are simultaneously displayed on the screen.
