Calibration system

The modular calibration system from GE Sensing and Inspection is a handheld test and calibration system that combines a multifunction calibrator with pressure measurement and generation capability.

Its modular concept allows its discrete components to be used as standalone instruments, allowing flexibility.

The DPI620 calibrator uses three basic components to perform duties formerly requiring a range of different instruments. At its core is its electrical, frequency and temperature calibrator.

This compact multifunction unit can measure and source mA, mV, V, ohms, frequency and a variety of RTDs and thermocouples.

Pressure measurement is provided by interchangeable pressure modules that attach to the calibrator via a carrier. The calibrator and the pressure modules can also be attached to a pressure generation station to form a fully integrated pressure calibrator.

Three pressure stations are available, so that pneumatic pressure from 95% vacuum to 20 bar or up to 100 bar can be generated, while hydraulic pressure capability is from 0 to 1000 bar.

The display can be configured to show up to six reading windows, which also act as active keys and, when pressed, expand to show more detailed information or provide other functions. Colour coding of displays is incorporated.

The calibrator can be expanded by adding hardware and software modules, including an Intecal field calibration and documentation manager, a wireless module and a 200 VAC measurement probe.

It is fitted with a HART configurator as standard to provide digital communication with HART devices for interrogation, configuration and calibration. The designed is also available in a Windows cost-effective-driven version, providing all the computing power of a conventional handheld PC or PDA.
