Overview
The PORUIKE BT-180A is a High Accuracy Ultrasonic Thickness Gauge designed for the measurement of the thickness of materials below 300 ° C (e.g. steel, cast iron). Based on the ultrasonic Measurement principle, it uses high temperature Probe and low power microprocessor technology to measure the Speed of sound of materials. The instrument is widely used to monitor the thickness of plates, pipes, boiler vessels, and the degree of thinning due to corrosion during use of various pipes and Pressure Vessels.
Features
1. Suitable for measurement of the thickness of good ultrasonic conductors such as metals (such as steel and cast iron) below 300 ° C.
2. Can be equipped with a variety of different Frequencies, different chip sizes of dual crystal Probe use.
3. With Probe zero-point calibrating, two-point Adjustment, the system error can be automatically corrected.
4. The known thickness can measure the Speed of sound to improve the Measurement accuracy.
5. With coupling status prompt function.
6. With LED backlight display, it is convenient to use in dim environments with rays of light.
7. There is a remaining power indicator function, which can display the remaining battery power in real time.
8. With power-saving functions such as automatic sleep and automatic shutdown.
9. Compact, Portable, Reliability, Suitable for harsh operating environments, Anti-Vibration, Impact and Electromagnetic Interference.
10. Capable of capturing minimum thickness values.
11. Measurement speed is fast, 4 times/second for single point measurement and 20 times/second for scanning mode.
Principle
BT-180A works based on the ultrasonic Measurement principle. The instrument emits ultrasonic pulses to the material under test through Probe, which propagates inside the material and reflects it back on another interface (or bottom surface), which is received by Probe. The instrument measures the time for ultrasonic waves to travel back and forth in the material, and combines the known Speed of sound in the material to calculate the thickness of the material. The user can also measure the Speed of sound of the material through the known thickness to improve the Measurement accuracy.
Applications
Various plate wall thickness measurement, pipe wall thickness measurement, boiler container wall thickness measurement, various pipe thickness measurement, Pressure Vessel thickness measurement, monitoring equipment after corrosion thinning degree
Standards
No specific compliance criteria were mentioned in the data.
Steps
1. Select the appropriate Probe according to the tested material and temperature and connect it.
2. Start the machine, and perform Probe zero-point calibrating or two-point calibrating if necessary.
3. Set or measure the Speed of sound of the material (Speed of sound can be measured by known thickness).
4. Apply a coupling agent to the measurement surface to smoothly couple the Probe to the measured point.
5. Read and record measurement results (the instrument has a minimum thickness value capture function).
6. The measurement data can be stored in the instrument (up to 20 groups of up to 100 values each), or exported through the RS232 interface.
Notice
* Please select the appropriate Probe (such as standard Probe, coarse crystal Probe, micro-diameter Probe or high temperature Probe) according to the type, thickness range and surface temperature of the material to be tested.
* When measuring, ensure that the Probe and the measured surface are well coupled through a coupling agent, and the instrument has a coupling status prompt function.
* Probe Contact Temperature range is -10~ 300 ℃ (standard Probe), high temperature Probe (HT5) can be used for materials with temperature less than 350 ℃.
* The lower limit of pipe measurement is φ 20 * 3mm.
* Note that the measurement error of the instrument is +/- (0.5% H + 0.04) mm.
* Clean Probe promptly after use.
* Pay attention to the battery level indicator. It is recommended to remove the battery when not in use for a long time.
The instrument has automatic sleep and shutdown functions to save power.
