The calibrator or process calibrator is used for basic measuring, testing and regulation techniques for setting and verifying test installations and instrumentation. A PCE calibrator is made of high strength materials and is lightweight and easy to be used handheld or can be fixed installed if necessary. This calibrator is valued by technicians due to its high level of accuracy and its universal range of applications.
No electrician or electrical technician should go without a process calibrator. The process calibrator is also instrumental within the industrial sector, especially within large facilities where many parameters of electrical measurement must be analyzed. The calibrator has different magnitudes that should be attributed to normal measurement signals. These measurement signals or regulated magnitudes are denominated as the test signal, which the calibrator can provide. They are defined as 0 to 20mA, 4 to 20mA, 0 to 10V and 0.2 to 1 bar. These magnitudes signify, for example, temperature, output or settings of a test valve (0 to 100% of valve opening). This signifies that for a regulating signal of 50% (eg. 10mA) with an input range of 0 to 20mA in a test valve, the valve opening will be 50%.
Some calibrators are task specific for instance a calibrator used to for infrared thermometers in laboratories. The calibrator’s thermal block, or black body serves as the source of radiation for calibrating pyrometers. This calibrator also allows for use of the thermal block in adverse conditions. The calibrator control unit is simple to utilize and has an easily readable display that shows the temperature being verified. A specialized cooling unit on the calibrator allows for temperatures to be raised or lowered quickly.
