With a built-in high performance electronic pump and precision pressure controller, the ADT761-M automated pressure calibrator provides a turn-key solution for calibration of gauges, transmitters, and switches both in the field and in the laboratory. In a portable package, this little calibrator can automatically generate from 90% vacuum to 375 psi (25 bar) pressure with 0.005%FS pressure control stability and 0.02%FS accuracy. To improve the calibrator accuracy, two pressure modules with differing ranges are used. These are built-in and integrated with the internal pump and controller. With optional external pressure modules (ADT160 series), the ADT761-M 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 ADT761-L also features HART communication capability, supply 24V loop power, and read the current or voltage produced by the pressure transducers. The state of art ADT761-M automated pressure calibrator brings automated pressure calibration to the field.
