Product Overview: 761-LA/MA/HA Automated Pressure Calibrator


• Fully automated pressure calibrator with built-in pressure generator / controller to as high as 600 psi (40 bar) or 615 psi.a (41 bar.a)

• 0.02%FS accuracy

• Dual pressure modules

• Built-in filter and liquid trap with venting system prevents contamination of the calibrator

• Portable (12.4 lb)

With a built-in high performance electronic pump and precision pressure controller, the 761 series portable automated pressure calibrators provide a turn-key solution for calibration of gauges, transmitters, and switches both in the field and in the laboratory. In a portable package, this calibrator can automatically generate pressures to 600 psi (40 bar) or 615 psi.a(41 bar.a) with 0.005% FS pressure control stability and 0.02% FS accuracy. To improve the calibrator accuracy, two pressure modules with differing ranges are built-in and integrated with the internal pump and controller.

With optional external pressure modules (160 series), the 761 can measure pressures up to 10,000 psi (700 bar) with 0.025%FS accuracy. In addition to the pressure generation, control, and measurement capabilities, the 761 also features HART communication capability, supplies 24V loop power, and reads the current or voltage produced by the pressure transducers. The 761 is a state of the art automated pressure calibrator which brings automated pressure calibration to the field.
