What is a Calibrator?

A Calibrator is an electrical device that simulates, and often measures, electrical signals such as voltage, current, and temperature (millivolts). Voltage and Current signals are referred to as ‘Process’ signals. These electrical signals simulate real world applications.Extech 412400 Calibrator

How are Calibrators used?

Calibrators are used to configure, calibrate, verify, and test a multitude of applications. For example, scales and ranges can be setup, adjusted, and verified on indicators and panel meters; Thermometers and other sensors can be tested for accuracy; Application simulations can be run on process controllers; Chart recorders, data-loggers, and other such data capturing devices can be configured, scaled, and tested.

Typical Calibrator Applications:

  • Configure the range & scale of indicators, process controllers, & recorders
  • Determine if a sensor is in need of replacing
  • Verify that products are manufactured in accordance with design or regulatory specifications
  • Assist in ISO-9001 and other Quality Systems, as to calibration lab compliance, documentation, and equipment verification

Choosing a Calibrator

Temperature Calibrators

In applications where temperature is measured, displayed, and controlled you’ll find devices such as sensors (thermocouples), indicators (panel meters), process controllers, chart recorders, and data-loggers. These devices must be configured and checked periodically and that is why a Calibrator is required. For temperature calibration calibrators, select the low cost 433201 or the multi-function 412400.

Current/Voltage Calibrators

Easily simulate process signals such as current and voltage.

Multifunction Calibrators

Can source/measure Current, Voltage and Temperature signals
