M&G deadweight testers (primary standards)
M&G Type T series (hydraulic)
Range: 100 to 10,000 kPa (10 to 15,000 psi)
These high accuracy deadweight testers are ideal for laboratory or field use. The type T tester uses distilled water or fluid compatible with 300 series stainless steel and MONEL (including AAA tester oil). For applications up to 15,000 psi (1,000 bar). An optional dual piston lets you interchange piston/cylinder assemblies to extend the pressure measurement range using the same weight set. A kit is available for converting to a dual column tester.
Deadweight testers are superior to all digital systems. Use the deadweight testers as your company's primary standard or to calibrate very critical pressure gauges as in custody transfer applications. In 1966, Mansfield & Green introduced the deadweight tester based on the ¡°floating ball¡± principle. This deadweight tester is an extremely easy-to-use, reliable and accurate primary standard and is now earning its reputation as the ¡°standard of standards¡±.
Typical deadweight tester applications are:
- laboratory or field use
- hazardous locations
- critical process control loops extending the time between calibrations due to better accuracy and uncertainty
- calibrating instruments on custody transfer stations thereby reducing the uncertainty of the measurement
- calibrating portable digital calibrators to achieve the highest possible accuracy and reducing maintenance costs
