Modular calibration system

The Advanced Modular Calibration System from GE Sensing & Inspection Technologies is a handheld test and calibration system that combines an advanced, multifunction calibrator with pressure measurement and generation capability. Its modular concept allows its discrete components to be used as standalone instruments, allowing significant flexibility both in cost of ownership and in functionality.

The system uses three basic components to perform duties formerly requiring a wide range of different instruments. At its core is its electrical, frequency and temperature calibrator. This compact and robust 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, high-performance 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. Each station can be fitted with an overpressure protection device to protect both the pressure module and the device under test.

The calibrator can be expanded by the addition of further hardware and software modules, including an Intecal field calibration and documentation manager, a wireless module and a 300 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 DPI 620 is also available in a Windows CE-driven version, providing all the computing power of a conventional handheld PC or PDA. The DPI 620CE provides standard Windows applications and file management.
