Working principle
Ultrasonic Thickness gauges for thickness measurement, is generated by the probes ultrasonic pulse through the coupling agent to be measured, part of the bottom surface of the ultrasonic signal is an object reflects, probes from the echo reflected from the bottom surface to be measured, accurately calculate the round trip time of ultrasonic, and according to the following formula to calculate the thickness value and the calculated results are displayed.
H=v×t/2
In the formula: h-measuring thickness
V-material velocity
T-in ultrasonic testing of round trip travel time
To ensure that the probes work, use a coupling agent to contact the sensor surface and the surface to be measured between the air and the fluid coupling used between the probe and the workpieces, known as coupling agent
Working conditions
Ambient temperature: operation temperature:-20 ℃ ~ + 50 ℃
Storage temperature:-30 ℃ ~ + 70 c
Relative humidity 90%
Environment no strong vibration, does not have a strong magnetic field, no corrosion and serious dust
Characteristics of the instrument

Has probe 0 points calibration, two points calibration function, can on system errors for automatically amendment known thickness can anti-measuring sound, to improve measurement precision has coupled State tips function has EL backlight displayed, convenient in light Dim environment in the using has remaining power indicates function, can real-time displayed battery remaining power has automatically dormant, automatically shut machine, saving function small, portable, reliability high, applies Yu bad of operation environment, anti-vibration, impact and electromagnetic interference
Operation methods and points for attention
How to probe plug into the sensor into the socket; Press open key, along with the power on beep, display the boot screen of the apparatus automatically into the main display, the parameters of the instrument parameters used for the last time before shutdown; In the power on State, press switch can implement the shutdown operation.
Set probe model: user requirements according to the actual situation and actual measurement, set the probe type. Setting method: in the main display, press the m key, choose the "sensor type" project; Press the up arrow and down arrow keys to select the desired probe model; Press the m key or the back button to exit the program.
Or: "measuring conditions"-"probe selecting" menu, press the OK button to enter the probe selection interface; Press the m key to switch to the data that you want to modify and press the up arrow and down arrow keys to select the selected probe; Press the OK button to confirm the selection, or press the back key to discard the selected measurement considerations
When measuring only a couple icons and stability, is a good measure;
If the surface to be measured when there is a lot of coupling agent, when the probe when they leave the surface to be measured, measuring error caused by coupling agent. At the end of a measurement, should quickly remove probe body surface being measured.
Acrylic resin surface probes, redrawing is very sensitive to rough surfaces, so should tap in use; When measuring the rough surface, minimizing probe paddling on the work surface.
Measurements at room temperature, the surface to be measured shall not exceed 60 c, otherwise the probe cannot be used again.
If head wear, instability of measurement indication appears, you should replace the probe.
Instrument care and maintenance
When the battery capacity is exhausted or spent should be to replace the battery, so as not to affect the measurement accuracy; Instrument battery should be removed when not in use for a long time, so as to avoid battery leakage, corrosion instrument boxes and the electrodes;
Instruments should be avoided and the probe has shaken the
Avoid equipment placed too wet environments
When you plug the probe should hold activities coat along the axis, and not rotate the probe to avoid damaging the probe cable wire
Oil, dust attached to the probe line is aging, break, cable should be cleared after use of dirt
Due to instrument calibration using a standard test blocks, coated coupling agent you want, so please note that blocks rust. Standard block clean after use. High temperatures when stained with sweat. Long-term use should be random blocks a little grease on the surface rust, when used again, after wipe grease, you can carry out work
Alcohol, diluted liquid have a corrosive effect on chassis, especially Windows, cleaning, wipe gently with a small amount of water to
