An accuracy statement defines the accuracy for a device, but several conditions must be met for the device to operate at this published specification.
One major differences between gauges is whether they offer “% of reading” vs. “% of full scale” accuracy.
If you work outdoors, your readings may be less accurate than you think. Understand how temperature effects pressure accuracy.
When you know what to look for, you can tell in advance which gauges can stand up to the elements you work in.
Because digital gauges use electronic firmware – rather than mechanical part – to manage their functions, they have great potential for customization.
When working with high pressure or flammable materials, it is important to select a gauge that helps avoid the occasional human error.
The lever action hand pump, which is supplied with both the type T & R hydraulic deadweight testers, incorporates a dual volume control valve.
Within the re-entrant piston and cylinder design, the test fluid is applied to a chamber on the outside of the cylinder as well as to the inside.
An accurate calibrating pressure is produced by bringing into equilibrium the pneumatic pressure on the underside of a ball of known area by weights of known mass on the top.
