Automated Pressure Calibrator

Manufacturer's part number :

ADT761

Manufacturer

Additel

Description :

With a built-in high performance electronic pump and precision pressure controller, the ADT761 series portable 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 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 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 also features HART communication capability, supplies 24V loop power, and reads the current or voltage produced by the pressure transducers. The state of art ADT761 automated pressure calibrator brings automated pressure calibration to the field.
