Additel Corporation, one of the leading worldwide providers of process calibration tools, has introduced the new ADT761 Automated Pressure Calibrators, designed to combine an electronic pressure pump, pressure controller, and pressure indicator for automatic pressure calibration in the laboratory as well as the field.
With a built-in high performance electronic pump and precision pressure controller, the ADT761 series 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 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, supplies 24V loop power, and reads the current or voltage produced by the pressure transducers. The ADT761 is delivered with an external pressure manifold, carrying case, and NIST traceable calibration certificate (with data). The ADT761 also comes with an extended warranty which cover parts and labor for factory defects for 18 months. The state of art ADT761 automated pressure calibrator brings automated pressure calibration to the field.
