Stella pneumatic pressure calibrators are designed to reproduce the unit of gas pressure during verification and calibration of pressure measuring instruments.
1) Upper limit of reproduction from 250 kPa to 630 kPa;
2) Lower limit of the main range of reproducible gauge pressure from 10 to 40 kPa.
3) Lower limit of pressure reproduction 0,6 kPa
4) Accuracy class: 0.01; 0.02; 0.05.
The principle of operation of the calibrators is based on the dynamic interaction of an unconsolidated piston and the flow of air flowing out of the nozzle, in which the force is balanced by the total weight of the piston, load receiving device and weights mounted on it.
