Pneumatic Deadweight Tester Accuracy to ±0.025% of Indicated reading 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, which can provide a reference pressure in process control applications. Repeateability ±0.005% of indicated reading Special Calibrations/Local Gravity HK testers are supplied standard with masses calibrated to International Standard gravity of 9.80665 m/s2. Local gravity calibration is available on all models. High Pressure Pneumatic Standard The HK is a high pressure pneumatic alternative to the available hydraulic standards. This series allows for selfregulating calibrations at high pressures without leaving a hydraulic residue in the UUT. Exceptional Performance and Safety Built-In - Floating Ball Operation Self-Regulating Rugged Ceramic Measuring Ball Overhung Weight Carrier Non-Contaminating Test Fluid Ball Valves for Inlet and Outlet Interchangeable Weights Prefill Supplied for Quick Filling Large Static Output Volumes NIST Traceable Self-regulating pressure standard The AMETEK HK Pneumatic Deadweight Tester is a primary standard that produces a pressure by applying force (weight set) over area (the ceramic ball and nozzle). The HK tester is NIST traceable and accurate to ±0.015% using stainless steel weights calibrated to International standard gravity at 9.80665 m/s2 or local gravity as specified. The HK tester is self-regulating with accuracy independent of the operator. The tester utilizes a virtually frictionless ceramic ball floating on a layer of air within a stainless steel cylinder. The HK tester features a quick-leveling system for lab setup. The unit may also be mounted on an optional tripod for more convenient setup. Weights are located in foam-protective slots in the case.

Model HK® Pneumatic Deadweight Tester FEATURES The following are some of the features and characteristics inherent to the AMETEK HK deadweight tester. Floating Ball While in operation, the HK tester’s ball and weights float freely, supported only by a thin film of air which is virtually frictionless. This eliminates the necessity to rotate the weights during testing and allows the user to concentrate on the instrument calibration. Self-Regulating The instrument’s built-in flow regulator automatically adjusts the input air flow to maintain the ball and weights in a float position. The regulator...

Model HK® Pneumatic Deadweight Tester FUNCTIONAL SPECIFICATIONS General Process Information for Calibrated Parts Local gravity values must be specified by customer in gals, cm/s2 or m/s2. Include serial number, accuracy, gravity, and model number of deadweight tester when ordering weight sets or calibrated parts. Masses for weights ordered separately, including tolerance, must be supplied by customer; unless combined with tester on same order. Calibrated parts may be made to archival data if requested on the purchase order. Calibrated parts are certified for physical dimension only (mass or area)...
