PK II Deadweight Tester The PK II floating ball type pneumatic dead weight tester is engineered to offer user-friendly, safe operation. The easy-to-use primary standard provides reliable and accurate pressure measurement in the field, or in a lab.
What is P&K?
(Entry 1 of 2) : the cologarithm of the dissociation constant K or −log K that serves as a convenient measure of the strength of an acid K for acetic acid is 0.000018 or l.8 × 10−5 from which pK is (5 − 0.25) or 4.75 — compare ph. PK.
What is a deadweight tester used for?
A deadweight tester is a calibration standard that uses the principle of a pressure balance to calibrate pressure measuring instruments. Deadweight testers use calibrated weights to apply known pressures to a device under test for a simple and cost-effective solution that covers a wide range of pressure calibrations.
What is hydraulic deadweight tester?
Deadweight testers are the high performance pressure standards for pressure measurement. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston.
What is PNL in accounting?
The profit and loss statement is a financial statement that summarizes the revenues, costs, and expenses incurred during a specified period.
How does a deadweight tester work?
Dead weight testers are a piston-cylinder type measuring device. They work in accordance with the basic principle that P= F/A, where the pressure (P) acts on a known area of a sealed piston (A), generating a force (F). The force of this piston is then compared with the force applied by calibrated weights.
Why is oil used in dead weight tester?
Dead weight testers are a piston-cylinder type measuring device. As primary standards, they are the most accurate instruments for the calibration of electronic or mechanical pressure measuring instruments. A special hydraulic oil or gas such as compressed air or nitrogen is used as the pressure transfer medium.
How is deadweight tester calculated?
The basic equation for the deadweight tester is:
P = F/A.
P = the pressure being derived.
F = the force applied by the weights.
A = the effective area of the piston cylinder.
PL = PA x GL/G.
PL = Actual Pressure at the local gravity of the test site.
PA = Actual Pressure as shown in the Calibration Report.
