Are pressure generation and control required?
| Most calibration procedures require comparison of the device under test (DUT) and calibration standard at multiple pressure points across the DUT’s range. Some DUTs or processes to be calibrated have built-in pressure generation and/or control, so it may not be needed by the calibration standard. Fluke Calibration offers a number of calibrator models with built in pressure control, and we offer generation and control pressure calibration accessories for when an external source is required. |
| Instrument Type | Models | Pressure Source (Generation and Control) |
| Gas pressure controller/calibrators | PPC4 7250 and 7252 |
Automated pressure control, requires test gas supply, and vacuum supply if used for sub-atmospheric control |
| High pressure gas controller/calibrators | PPCH-G 7350 |
Automated pressure control, requires high pressure test gas supply (gas booster may be needed) and industrial grade gas supply (shop air) |
| Hydraulic pressure controller/calibrators | PPCH 7615 |
Automated pressure control. Onboard hydraulic pressure generation, requires industrial grade gas supply (shop air) |
| Reference pressure monitors | RPM4 7050 |
Measures pressure only. Requires external manual or automated pressure generation and control, such as MPC1, GPC1, MPG2, OPG1, PPC or 3990, 7000 pressure controllers. |
| Electronic deadweight tester | E-DWT | Onboard manual pressure generation and control with hydraulic priming pump and variable volume |
| Gas deadweight testers | P3010 P3020 |
Floating piston precisely controls pressure. Onboard manual pressure generation available from vacuum to 300 psi (2 MPa) with hand pump |
| High pressure gas deadweight testers | P3030 | Floating piston precisely controls pressure. Onboard manual pressure adjustment, requires high pressure test gas supply |
| Hydraulic deadweight testers | P3100 P3200 M3800 |
Floating piston precisely controls pressure. Onboard manual pressure generation and adjustment with hydraulic priming pump and variable volume |
| Absolute/gauge piston gauges | PG7601 2465 2468 |
Floating piston precisely controls pressure. Requires external manual or automated pressure adjustment, such as MPC1, PPC4 or 3990. Requires vacuum pump for absolute mode measurement |
| Gas piston gauges (gauge-only) | 7102 7202 2470 |
Floating piston precisely controls pressure. Requires external pressure generation (gas booster may be needed) and manual or automated pressure adjustment, such as MPC1, GPC1, PPC4, PPCH-G or 3990. |
| Hydraulic piston gauges | PG7302 2485 |
Floating piston precisely controls pressure. PG7302 requires external manual or automated pressure generation and adjustment, such as MPG2, OPG1 or PPCH. 2485 includes onboard manual pressure generation and adjustment |
| Handheld process calibration tools | Fluke 71x Calibrators Fluke 700P Modules |
Onboard gas pressure generation available from vacuum to 300 psi (2 MPa) Other ranges measure pressure only, require external manual pressure control. |
