Ametek PK II Pneumatic Deadweight Tester PK2 Accurate to 0.015% of Reading, Ranges from 4 Inches of Water to 30 PSIG

Ametek PK Deadweight Tester

Ametek PK II Deadweight Tester PK2


Ametek PK II PK-2 Deadweight
Tester


The AMETEK PK II Pneumatic Deadweight Tester is a primary standard that produces a pressure by applying force (weight set) over area (the ceramic ball and nozzle). The PK II tester is NIST traceable and accurate to +/- 0.015% using stainless steel weights calibrated to international standard gravity at 980.665cm/sec2.

The PK II 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 PK II tester features a cast-metal base with a quickleveling system for field or lab setup. The unit may also be mounted to an optional tripod for more convenient setup. The tester may be operated with the cover opened or closed. Weights are located in foam-protective slots in the case.

Special Calibrations/Local Gravity
The PK II tester are optionally available with an accuracy of
+0.015%. Calibration to your local gravity is available for all
stainless steel models. Please provide your gravity when ordering.

Gas Industry Models

Standard testers in inches or cm of H2O are calibrated reference
water columns at 20 Deg C (68 Deg F) per ISA recommended
practices. Calibration to reference water columns at 60 Deg F per
AGA standards is available. Contact us at (732) 632-6400 for details.

Floating Ball

The PK II tester is a floating ball-type, pneumatic deadweight tester with many features designed to improve performance and safe operation when used according to the instrument’s operating instructions. Listed are some of the inherent features of the AMETEK PK II Deadweight Tester.

While in operation, the PK II 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 also compensates for variations in pressure from the air supply. These features eliminate the necessity of having to continually adjust the supply during the test.

Rugged Ceramic Measuring Ball

The floating ball/piston is manufactured from aluminum oxide ceramic - a material with near-diamond hardness. The ball, unlike steel and carbinde pistons, may be dropped on hard surfaces without damage.

Quick Setup and Operation

The setup for the PK II tester is completed by simply connecting two tubes and adding the appropriate weights. Operation is fast and efficient with no valves to adjust and no regulation needed between set points. Pressure regulators are not required if the air supply is within the tester’s operational requirements.

Non-Contaminating Test Fluid

The instrument’s test fluid is Nitrogen or instrument quality air complying with the ISA Standard S7.3. This fluid is non-contaminating to virtually all processes, thus eliminating the need to clean instruments after calibration and before use.

Tripod Mounting

The PK II tester is designed for laboratory and portable use in the field. The instrument includes built-in tripod mounts. A tripod may be ordered separately.

Closed Cover Operation

The PK II tester is designed to operate with the cover closed, thus eliminating the effects of wind during field operation.

Ball Valves

AMETEK floating ball testers, such as the PK II tester, incorporate multi-position ball valves for both the inlet and outlet valve connections. These ensure trouble free operation that is both fast and efficient.

Certification of Accuracy and Traceability

A Certfication of Accuracy and Traceability to NIST is included with every AMETEK floating ball-type deadweight tester. An optional Certification of Accuracy with area, mass and intrinsic correction factors is available.
