ADT761 Automated Pressure
Calibrator
|
|
- Fully automated pressure calibrator with built-in pressure generator/
controller to 375 psi (25 bar)
- 0.02%FS accuracy
- Dual pressure
modules
- Portable (12 lb)
|
With a built-in high
performance electronic pump and precision pressure controller, the ADT761 series
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 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, supply 24V
loop power, and read the current or voltage produced by the pressure
transducers. The state of art ADT761 automated pressure calibrator brings
automated pressure calibration to the field.

* ADT761 calibrators support ADT160 series
intelligent digital pressure modules that are available for gauge, vacuum and
absolute pressure from -15 psi to 10,000 psi (-1 bar to 700 bar). Accuracy from
0.025%FS includes operation over 14°F to 122°F (-10°C to 50°C), one year
stability and calibration uncertainty. For detailed specification refer to
ADT160 series pressure modules datasheet.
