pressure comparators
What we offer?
Budenberg offers wide range of Pneumatic and Hydraulic Pressure comparators, Handheld Hand Pump and Test kits with or without Test Gauges covering pressure range from vacuum to 4000 bar (60 000 lb/in²) .
Pneumatic and Hydraulic pressure comparators are used to generate pressures with gas / liquid media so that a device under test can be compared with a reference gauge. Budenberg offers wide range of pressure comparators to handle different pressure ranges up to 500 MPa (75,000 psi).
Suitable Reference (Master Test) Gauges are described in “Master Test Gauges” under Calibration Instruments.
Description
With ABS cover, all working parts of the comparator are fitted to the aluminium base with four Adjustable feet for levelling. There are two Union Connectors, one for Test Instrument and the one for Instrument to be Calibrated.
Two Precision soft seat valves are fitted, one valve admits air into the system from inlet and the other vents the system to atmosphere. The Screw Press (Volume adjuster) is fitted to makefine adjustments of Pressure / Vacuum.
The base requires external Gas supply slightly above test Pressure. The entry port ¼”BSP Female is at the back. A safety pattern gauge is fitted to show the approximate inlet pressure.
Special Applications
For Calibration of Oxygen gauges, the comparator and Test Gauge (if ordered) is degreased to make it suitable for calibrating oil free instruments particularly gauges used on Oxygen.

Description
This comparator is designed to test a pressure gauge by comparing the gauge with a test gauge. Suitable Standard Test Gauges are described in section “Master Test Gauges” under Calibration Instruments.
The comparator is of a simple robust construction consisting of screw pump, reservoir and two ½”BSP connections with shut off (isolating) valves.
The tester has aluminium base with holes for bench mounting. It should be bolted to bench for rigidity. The tester is designed for use with most mineral based hydraulic oils. It can also be used on water but should be informed when ordering.

Description
All the working parts of the comparator are mounted on a tough anodised aluminium base which has four levelling screws at the corners. The ABS cover is retained by four screws and bears an instruction plate on the raised position. All the parts in contact with medium are rust free. The oil reservoir has a transparent cover and can easily be filled.
Twin Area Screw Pump
When operated with valve ‘A’ open and valve ‘B’ closed the large diameter ram generates pressures up to 140 bar (2000 lb/in²) quickly. When operated with valve ‘B’ open and valve ‘A’ closed the small diameter ram builds up higher pressures easily and small adjustments are readily made.
The stainless steel pump spindle has a rolled trapezoidal thread and the thrust is taken by a needle thrust bearing to cut down effort required. The brass high pressure block in the pump contains valves ‘A’ and ‘B’ and the oil reservoir. From this block stainless steel pipes lead to the piston unit and gauge stand.
