ConST811 Automated Pressure Calibrator
• Ranges from 90% vacuum to 25bar (375PSI)
• 0.02%FS pressure uncertainty
• Only 5.6Kg
The ConST811 is a revolution in pressure calibration technology for the process industries. With the ConST811, technicians have a compact, light weight calibrator that generates from 90% vacuum to 375 PSI (25bar) using a high performance integral electric pump.
In a portable package, this little calibrator can automatically generate from 90% vacuum to 375 psi (25bar) 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 (CDP series), the ConST811 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 ConST811 also features HART communication capability, supply 24V loop power, and read the current or voltage produced by the pressure transducers. The state-of-the-art ConST811 automated pressure calibrator brings automated pressure calibration to the field.
