With a built-in high performance electronic pump and precision pressure controller, the Additel 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 (Additel ADT160 series), the Additel ADT761 Automated Pressure Calibrator 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 Additel ADT761 also features HART communication capability, supplies 24V loop power, and reads the current or voltage produced by the pressure transducors. The state of art Additel ADT761 automated pressure calibrator brings automated pressure calibration to the field.
Pressure Range: Pressure generated by built-in pump and controlled automatically from 90% vacuum to 15 psi (40 bar). Pressure measured with external pressure modules (160 series) to 10,000 psi (700 bar). Accuracy (Fully temperature compensated) 0.02%FS; 0.05%FS (ADT761-LLP)
Control Stability: <0.005%FS. ADT761-LLP: < 0.05 Pa (0.0002 inH2O)
Contamination prevention system: Built-in filter and liquid trap with venting system prevent contamination of the calibrator. Solid particles can be blocked by built-in filter. A small amount of Liquid can be collected by the built-in liquid trap. Both solid particles and liquid can be blown out through the venting system
Automation and Test Program: Fully Automated pressure calibration. Task preset and auto run. Auto step
Easy to Use: User friendly interface. Intuitive icon driven menu structure
Sourcing and Measuring electrical signals: Measure mA with 0.01%RD + 1.5μA accuracy. Measure V with 0.01%RD + 1.5mV accuracy. Source/sink 0 to 22mA current. 24 VDC loop power supplied to pressure transmitter during test. Automated switch test
Misuse Protection: Up to 30V misuse protection on any two sockets.
