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.
