| » PRODUCT DESCRIPTION The AMETEK HK Pneumatic Deadweight Tester is a primary standard used to calibrate pressure and differential pressure gauges, transmitters, transducers, recorders and controllers, and that can provide a reference pressure in process control applications. The HK tester is self-regulating with accuracy independent of the operator. These testers feature superior accuracy and repeatabilityａnd a prefill feature that minimizes the filling of large static output volumes before the test. » FUNCTIONAL SPECIFICATIONS Accuracy +0.025 PSI or +0.025% of indicated reading (whichever is greater) Repeatability 0.005% of output reading Temperature Coefficient 0.00167% of output per oC based on 23oC Maximum Supply Pressure 1500 PSIG (2000 PSI for HK-1500) Instrument quality air per ISA Quality Standard S 7.3. Minimum Supply Pressure 150 PSIG or 150% of output pressure, whichever is greater Flow Rate 3 SCFH at 10 PSIG output 50 SCFH at 1000 PSIG output 100 SCFH at 1500 PSIG output The HK tester is available in these ranges: q 10 to 300 PSIG q 10 to 500 PSG q 10 to 700 PSIG q 10 to 1000 PSIG q 10 to 1500 PSIG The HK tester is very easy to setup and use. The unit’s precision stainless steel weights are calibrated for international specific gravity of 980.665cm/sec2 » PHYSICAL SPECIFICATIONS Connections 0.25-inch OD tubing, 7/16-20, 37o AN angle Weight Tester Only ............................... 18 to 31.5 lbs (8.2 - 14.3kg) Weights .................................... 17.5 to 61.5 lbs (8.0 - 30.0kg) Shipping Dimensions (L x W xH) Tester ....................................... 16.0 x 16.0 x 16.0-inches (40.6 x 40.6 x 40.6 cm) Weight Set Storage Case ........ 2.0 x 12.0 x 12.0-inches (5.1 x 30.5 x 30.5 cm) Notes: Deadweight tester and deadweight gague accuracy is expressed as “Percent of Indicated Pressure”. A 1000 psi tester with an accuracy of +0.01% of indicated pressure will have an allowable error of 0.1 psi at 10 psi, +0.1 psi at 100 psi and +1.0 psi at 1000 psi. Generally, deadweight testers are used only in the upper 90% of the range. |
