Overview
The HCH-3000E-E High Accuracy Ultrasonic Thickness Gauge is a smart Ultrasonic Thickness Gauge that integrates transmit-echo mode and echo-echo mode. It adopts the integrated system technology of single chip microcomputer and CPLD, and has the characteristics of low power consumption, strong penetration, stable indication, high detection accuracy, and humanized Operating interface. It also adds functions such as Probe identification, batch group management data, multiple online Measurement modes, and Speed of sound measurement, making it more suitable for the work needs of industrial sites.
Features
1. Measurement modes of primary bottom wave and echo-echo
2, pulse~ echo mode (standard mode, for ordinary thickness measurement)
3, echo~ echo mode (coating mode, for the measurement of the net thickness of the substrate without removing the paints layer)
4. Speed of sound: The speed of sound can be measured according to the thickness of the known material
5. Automatic Sensitivity gain optimization - automatically adjust Sensitivity to make measurement more accurate
6. Probe automatic identification, optional multiple Probe
7, MIN Minimum scan mode, 10 times per second, fast measurement and capture MIN Minimum
8, can set the upper and lower limit alarm threshold, when the measurement thickness exceeds the threshold, the alarm signal is given
9, difference mode: the thickness of the measurement is compared with the set base value, and the difference is displayed on the screen
10. Mass storage, data packet management
11. The printout can communicate with the PC
Principle
The Ultrasonic Thickness Gauge uses the principle of ultrasonic pulse reflection for measurement. In standard mode, Probe emits ultrasonic pulses to the material under test, and the pulses reach the bottom surface of the material and are reflected back. The instrument calculates the thickness of the material by calculating the time difference between the emitted and received echoes, combined with the known Speed of sound. In coating mode, the instrument uses echo-echo technology to calculate the net thickness of the substrate by measuring the time difference between two consecutive echoes inside the material, eliminating the need to remove surface coatings.
Applications
Industrial site thickness measurement, substrate thickness measurement with coating, Speed of sound measurement
Steps
1. Select the appropriate Probe according to the measurement requirements and connect it.
2. When turned on, the instrument will automatically identify the Probe.
3. Measurement mode (standard mode or coating mode) is selected according to the tested material.
4. If necessary, Speed of sound calibrating or reverse measurement Speed of sound.
5. Coupling the Probe to the surface of the material under test.
6. Measured values are read and recorded, and data can be stored manually.
7. Specific measurements can be made using Difference Mode, MIN Minimum Scan Mode or Alarm Function.
8. After the measurement is completed, it can communicate with the PC through the Interface or print out.
Notice
* Measurement range is affected by the Probe used, the material measured and the surface condition, the standard mode is 0.8~ 500mm, and the coating mode is 3.0~ 20mm.
Make sure the Probe is well coupled to the surface under test for accurate readings.
* Note Ambient Temperature -10~ 60 ℃, relative humidity < 90% RH.
* Powered by 2 AA batteries, please pay attention to the power.
* The measurement error is related to resolution and thickness, please select the appropriate setting according to the accuracy requirements.
* Data storage method is manual storage, please pay attention to save important data in time.
