The elcometer is designed on the precept of ultrasonic sound waves reflection to measure the thickness of fabric. On this article, I’ll introduce it step-by-step.
1. Have a normal understanding of an elcometer
Generally, the elcometer is made up of two predominant components, the host and the probe. The host is just like the mind of the elcometer, which is made by SCM. In measurement, it controls transmitter circuit, receiver circuit and show circuit. The probe may be seen as a hand of elcometer. It will possibly transmit and obtain ultrasonic sound waves that are utilized by elcometer to test the thickness of coating. In calculating of thickness, the delay between echoes of ultrasonic waves on the probe-face is the same as the time wanted to go via the fabric twice, so the true thickness is the space which is the same as the ultrasonic wave velocity within the materials multiplied by half the time.
2. Learn the directions appropriately
Should you use an elcometer for the primary time, it’s a necessity to learn and perceive the directions appropriately. Nearly every part in regards to the elcometer, together with the lifetime of this product and upkeep strategies are listed on it. Right here, we clarify a number of essential objects to make our examine higher and simple. The primary is bodily parameters, the place we are able to discover weight (typically together with batteries), dimensions, gauge working temperature and case.
Then, we should always take discover of the measuring vary and precision to see if it will possibly fulfill our necessities. Discover the a part of the minimal substrate thickness (typically illuminated with precision collectively), and browse it rigorously. Take care that the minimal substrate thickness is totally different with totally different measurement supplies.
The third is measurement pace. All types of elcometer made in numerous factories will present you there pace values, similar to 60 readings per minute.Do not forget that excessive pace of measurement will deplete the battery power rapidly and make your probe hotter. Thus, when measuring excessive temperature supplies, the measurement pace have to be diminished to forestall overheating of the probe. It is helpful to see the probe working temperature. Principally, the worth proven on it’s the most temperature the probe can nonetheless work.
The final is the battery. Test battery kind and life to see whether it is attainable to substitute it by a brand new one when it will possibly’t work.
3. Distinguish the probe
The probe is the half utilized in each measurement. There are two varieties of probe outfitted in elcometers, the integral probe and the separate probe. The integral probe signifies that you need not match probe by your self however it’s inconvenient in measuring, whereas the separate probe is within the opposition.
You have got discovered in regards to the elcometer adequately. It is higher to have a follow now.
