ConST 811 automated pressure calibrator

The ConST 811 automated pressure calibrator is a compact, lightweight calibrator that can generate from 90% vacuum to +25 bar (375 psi). It is suitable for field test, service and commissioning applications.

The easy-to-use calibrator can automatically provide the required pressure with a control stability of 0.005% FS and accuracy of 0.02% FS.

The unit has a large, easy-to-read display with a 7″ colour screen and an intuitive icon-driven menu structure for device under test and task selection.

Hart communications is supported and a 24 VDC loop power is provided, as well as reading the current or voltage of the pressure transmitter or transducer under test.

With optional external pressure sensors, the calibrator can measure pressures up to 700 bar (10,000 psi) with 0.025% accuracy.

A rechargeable battery gives 8 h of operation between charges and the internal memory stores 120 tasks. Full documenting facilities are available. The unit has a leak test/switch test facility.
