Calibration – Types and applications
1. Calibration is a method used to test and adjust machines to maintain accuracy in the working of a machines, devices and other equipment.
2. Calibration services are used in multiple sectors, such as:
a. Connectivity,
b. Home entertainment,
c. Production plants,
d. Mechanical,
e. Automotive,
f. Power distribution, and more.
3. Though calibration in general refers to measuring and rectifying errors in the working of equipment, there are many methods of calibration in use today.
4. The most common techniques of calibration used are:
a. Mechanical calibration,
b. Electrical calibration,
c. Temperature calibration, and
d. Pressure calibration.
5. Mechanical calibration:
mechanical calibration is used to test various mechanical equipment like torque wrenches, accelerometers, micrometers and load cells.
This process is usually carried out in a controlled facility, where various elements can be safely tested
6. Electrical calibration:
This technique is used to test and measure the frequency, voltage, and resistance of current and electrical equipment.
this technique is commonly used to calibrate equipment like
Data loggers,
Counters and timers,
Loop testers,
Multi-meters, and
Insulation testers.
7. Temperature calibration:
Both temperature and humidity calibration is performed in a controlled environment. These techniques use many instruments in the calibration process, such as
Humidity recorders,
Thermometers,
Weather stations,
Infrared meters,
Data indicators, and
Thermal cameras.
8. Pressure calibration:
pressure calibration is used to measure gas and hydraulic pressure. Pressure balance and calibration instruments are used along with various gauges to determine the pressure and make adjustments accordingly.
Equipment that require pressure calibration include
a. Analogue pressure gauges,
b. Barometers,
c. Digital indicators, and
d. Digital pressure gauges.
