Deadweight testers

UK-based Pressurements Limited manufactures deadweight testers for the accurate measurement of pressure. These testers have greater stability, repeatability and accuracy. These testers are ideal for calibrating pressure gauges, transducers, transfer standards, recorders and digital calibrators and can also be used to measure directly the pressure in systems and processes where precise readings are important. These testers utilise the well-proven piston gauge system, consisting of a vertically mounted precision lapped piston and cylinder assembly. Accurately calibrated masses are loaded onto the piston, which rises freely within its cylinder. These weights balance the upward force created by the application of pressure within the system. Instruments are supplied calibrated to standard gravity 980.665 cm/s^2 with an integral carrying case, which makes them neat, compact and easily portable. Components are stowed in the detachable lid, which also provides excellent protection from dirt and damage when the tester is in transit or storage. Unique test-station connections allow quick hand-tight sealing, no need for teflon tape and spanners. A spirit level and adjustable feet are provided to enable the operator to level the instrument. A floatation indicator is mounted on the top plate removing guesswork when floating the piston. Weights are stored in a separate box except for low-pressure pneumatic models. Standard features of these testers are as follows: calibrated weight set in carrying case; 1/8", ?", 3/8", ?"BSP or NPT female adaptors; operating fluid (where applicable) and spare seals.
