The Advanced Modular Calibration System from GE Sensing & Inspection Technologies is a handheld unit that combines a multifunction calibrator with pressure measurement and generation capability. At its core is an electrical, frequency, and temperature calibrator. The unit can measure and source mA, mV, V, ohms, frequency, resistance temperature detectors, and thermocouples. Pressure measurement is provided by interchangeable pressure modules that attach to the calibrator via a carrier. The calibrator and pressure modules can also attach to a pressure generation system to form an integrated pressure calibrator. Three pressure stations enable the generation of pneumatic pressure from 95% vacuum to 20 bar (290 psi) or up to 100 bar (1450 psi), while hydraulic pressure capability is 0 to 1000 bar (0 to 14,500 psi).
