Overview
MT200 Ultrasonic Thickness Gauge is a measuring instrument based on the principle of ultrasonic propagation. It can perform Film thickness measurement on various ultrasonic good conductor materials such as metal, plastic, Pottery and porcelain, Glass, etc., and supports sound speed reverse measurement. It adopts a sealing metal shell design, which can effectively prevent oil, dust and other harsh environments. Compared with the traditional method, the instrument only needs to contact one side of the workpiece to complete the measurement, and its nondestructive detection characteristics provide an efficient solution for the film thickness detection of closed or restricted working conditions such as pipes and containers. It is widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields for monitoring equipment corrosion thinning or precision measurement.

9. With coupling status prompt function.
10. Can be equipped with a variety of frequencies, chip size Probe use.
Principle
The MT200 Ultrasonic Thickness Gauge works based on the principle of ultrasonic propagation in materials. The instrument emits ultrasonic pulses to the material under test through Probe. After the pulses reach the bottom surface or interface of the material, they are reflected back to Probe. The instrument measures the time for ultrasonic waves to travel back and forth in the material. When the material sound velocity is known, the material Film thickness can be calculated according to the propagation time; if the standard Film thickness is known, the material sound velocity can be calculated in reverse for calibrating and improving subsequent measurement accuracy.
Applications
Petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace
Standards
The data did not mention specific compliance criteria.
Steps
1. Select the appropriate Probe according to the tested material and connect it.
2. Start the machine, and perform single-point calibrating or two-point calibrating as needed to correct the system error.
3. For improved accuracy, sound velocity can be measured using known Film thickness samples.
4. Select single point measurement mode or scan measurement mode.
5. Use a coupling agent between the Probe and the material under test to ensure good coupling (the instrument has a coupling status prompt).
6. Probe stable contact with the measured point for measurement.
7. Film thickness upper and lower limits can be set in advance, and the instrument will automatically alarm when the measurement value exceeds the limit.
8. After the measurement is completed, the data can be transferred to the computer through the RS232 interface or connected to the micro printer to print the report.
Notice
* Operating Ambient Temperature should be between -20 ° C and + 50 ° C, Storage Temperature should be between -30 ° C and + 70 ° C.
* The relative humidity of the working environment should be ≤ 90%.
* Avoid use in environments with strong vibration, strong magnetic fields, corrosive media and severe dust.
* When measuring, ensure that there is good acoustic coupling between the Probe and the tested surface (using a coupler).
* For pipe measurement, the lower limit is φ 15mm (outer diameter) * 2mm (wall thickness).
* The instrument is powered by 3V (2 AA alkaline batteries in series), please pay attention to the power indication.
When connecting a computer or printer, please use the interface and model specified by the manufacturer.
