Inclined-piston deadweight pressure gage (OCoLC) Material Type: Government publication, National government publication: Document Type: Book: All Authors / Contributors: Donald R Douslin; J P McCullough; United States.

Bureau of Mines. In a Deadweight Gauge, the area is the piston, and the masses are the weights. The Deadweight Gauge concept: The unknown pressure is admitted at the pressure connection, pushes down on the top of the oil, and in turn forces the piston and table upward.

Pascal’s Law tells us that fluid pressure is equal and undiminished in all directions. The deadweight gauge, also known by the alternative names of piston gauge and pressure balance, is shown in the schematic Inclined-Piston Deadweight Pressure Gage.

book in Figure It is a null-reading type of measuring instrument in which weights are added to the piston platform until the piston is adjacent to a fixed reference mark, at which time the downward force of the weights on top of the piston is balanced by the pressure.

-Assemble Bourdon’s pressure gauge with dead weight tester -Apply pressure in terms of weights on table and measure the value of it on pressure gauge -Repeat the procedure for ascending and descending weights on table and corresponding 7.

Apparatus: weights bourdon gauge weight support base plate 8. A double-primary dead-weight tester for pressures () kPa in gage mode. High pressure inactivates V. parahaemolyticus and B. cereus. Type AR analog durometer. A small-volume apparatus for the measurement of phase equilibria.

The normal calibration procedure is to load the gauge with known pressures, using a dead weight tester using oil. The present experiment, however, works satisfactorily with water instead of oil. Objective(s) of the Experiment. The test is carried out in order to calibrate a pressure gauge using a dead tester.

Equipments and Materials Needed. A dead weight tester apparatus uses known traceable weights to apply pressure to a fluid for checking the accuracy of readings from a pressure gauge.A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston.

Deadweight testers are so called primary standards [citation. The deadweight piston gauge (Bell and Howell) is used is to measure pressure in terms of fundamental units - force and area.

A piston is inserted into a close fitting cylinder. Weights are placed on one end of the piston and are supported by fluid pressure applied to the other end. Now the pressure gauge to be calibrated is fitted at an appropriate place on the dead weight tester.

The same known weight which was used to calucated P is placed on the platform. Due to the weight, the piston moves downwards and exerts a pressure P on the fluid. Make Offer - Ruska 15, PSI Hydraulic Pressure Piston Gage Dead Weight Tester Primary.

Douslin and J. McCullough. Experimental values of vapor pressure for 15 hydrocarbons are measured in the low-pressure range to 25 mm hg by means of the inclined-piston deadweight gage and in the range 71 to 2, mm hg by means of comparative ebulliometers.

Correlations of the present results with selected literature values are given in terms of cox equations. – Pressure Calibration needs to satisfy accuracy requirements of the Device Under Test (DUT).

– For High End precision Calibration, at normal to elevated pressures, the use of Deadweight Piston Gauges is necessary.

Product details. Item Weight: pounds Shipping Weight: 2 pounds. the position, bear in mind the pressure difference between the test point and the Dead-weight gauge. Remove the box by unfastening the toggle clamp. PACKING LIST The system carton should contain: 1 - copy of the operating and maintenance instructions (this manual) 1 - Dead-weight gauge in carrying case (Fitted with blanking plug).

Jain et al. derived the pressure coefficients for both piston and cylinder for this gage using elasticity theory and the thick-wall formula. (In that report the gage is referred to as NIST) They used a value b = × 10 −12 Pa −1 for the pressure coefficient of the gage.

Dead-weight pressure measuring instruments 9 Indirect pressure measurement instruments 11 Pressure measuring instruments with flexible elements 11 Electrical pressure sensors and pressure measuring instruments 13 • Sensor types with strain gauges 13 • Strain gauge transmission principles 21 • Diaphragm conversion 21 •.To carry out tests or calibrate a pressure gauge with the dead weigh tester(DWT), accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder.

These weights balance the upward force created by the pressure within the system. The dead weight tester is basically a device for measuring pressure and producing pressure. It is used to calibrate manometers. The following procedure is adopted to calibrate manometers. Gauge calibration means entering a precisely known pressure sample into the manometer under test and then observing the response of the manometer.
