2 Features & Benefits Ashcroft est Gauges 2 Dresser engineers have developed a new generation of test gauges to meet the exacting needs of instrument engineers and quality specialists. he new Ashcroft test gauge can be used as a transfer standard for periodically checking the accuracy of pressure instruments or as a laboratory instrument for research and test labs. he wealth of new features make it an excellent test gauge for process applications where high accuracy in pressure measurement is essential. External adjustable dial facilitates compensation for tare or zero adjustment on standard case style ype 082(*)S only. emperature compensated movement that significantly reduces temperature error. onventional test gauge accuracy is adversely affected as the ambient temperature varies from that at which the gauge was calibrated. his inaccuracy can be as much as 0.02%/ F or 2% for a 25 F temperature change. he 4 2 and larger Ashcroft test gauges include a special bimetallic element which automatically reduces ambient temperature errors to less than 0.005% per degree F. Some manufacturers reduce temperature error by using NiSpan for bourdon tubes. his material is subject to serious corrosion problems in some applications. he Ashcroft temperature compensated movement allows use of Monel bourdon tubes for corrosion resistance superior to NiSpan while still providing excellent temperature stability. *Bourdon tube designation (see page 4). MicroSpan adjustment for ease in span calibration. his device permits precise adjustments to achieve exact span calibration from 0 to 00% of scale. he micrometer screw attached to the slide will vary the span by approximately 2% per 360 rotation. he long life bourdon tube is capable of sustained accuracy, yet is suitable for process applications. he Ashcroft test gauge uses the Ashcroft Duragauge pressure gauge bourdon tube perhaps the most highly developed bourdon tube in the world. Proven and refined by years of rugged service in demanding process applications around the world, this outstanding pressure element is standard in all 4 2, 6 and 8 2 size Ashcroft test gauges. Hydraulically staked movement provides improved stability. he movement, with eflon coated gears and bearings, uses a unique hydraulic staking operation to ensure a rigid movement frame that resists shift due to shock and vibration. High and low pressure movement stops are standard to protect the gauge against calibration shifts caused by accidental overpressure, and to limit pointer rotation. Improved dial and pointer results in excellent readability.

7 7 Product Selection Ashcroft est Gauges SANDARD ASE SYLE YPE 082 onsult ASME B40. for guidance in gauge selection WARNING: Pressure gauges should be selected considering media and ambient operating conditions, to prevent misapplication. Improper application can be detrimental to the gauge, causing failure and possibly personal injury or property damage. he information contained in this catalog is offered as a guide to assist in making the proper selection of a test gauge. Pressure Ranges: For process applications, select a gauge with a full scale pressure range of approximately twice the normal operating pressure. he maximum operating pressure should not normally exceed 75% of the full range. For laboratory applications, where cycling is less frequent, the range of the test gauge may be the same as that of the instrument under test. Operating onditions: o ensure long life and accurate readings, pressure gauges should not be exposed to process or ambient temperatures over 50 F. his is especially true of gauges with liquid filled cases due to thermal expansion of the case fill fluid. Long term exposure to temperatures in excess of 50 F may cause discoloration of dials and fill fluids, as well as hardening of elastomeric case seals and possible fill leakage. Soft soldered, silver brazed and welded pressure joints are rated at 250 F maximum, 450 F maximum and 750 F maximum respectively. Plastic gauge cases, including phenolic should not be exposed to temperatures in excess of 250 F. Accuracy of temperature compensated ype 082 gauges will be affected by approximately 0.005% per degree F and accuracy of all other test gauges will be affected by approximately 0.05% per degree F. ases: Six different case styles and three different materials are offered aluminum alloy, fiberglass reinforced polypropylene, and phenolic. wo types are offered, open and solid front. he open front ype 084 case is constructed with the dial between the bourdon tube and the window, with a pressure relief opening between the socket and the case. he solid front cases supplied on all other test gauges provide increased safety with a solid wall between the bourdon tube and the window. he entire rear of the gauge is covered with a stainless steel pressure relief back. Should the Bourdon tube fail due to overpressure, corrosion or fatigue, the wall directs pressure buildup through the rear of the case and away from the dial and the window. Bourdon ube Pressure Elements: Available for a wide variety of media applications; materials include phosphor bronze and K-Monel. Movement: All gauges 4 2 size and larger feature a rotary geared movement, the most efficient and positive method of transmitting mechanical motion. Moving parts are designed and protected to reduce friction and wear. All movements are ultrasonically cleaned and lubricated to guarantee smooth operationand to resist wear associated with high vibration and/or pulsation. Span, linearity, and zero adjustments are easily made to assure continued accuracy of all Ashcroft test gauges. Dials: Aluminum dials have highly legible black markings on a white background. Each test gauge dial has a mirror band which eliminates parallax errors when the pointer and its reflection are aligned. External adjustable dial available in standard case style 082(*)S. Pointers: Balanced knife-edge tip pointers, supplied with all test gauges, allow precise and easy readings. All are lightweight to maintain a high standard of accuracy. ype 082 and 084 pointers include a red tip for enhanced readability. Windows: he standard window for ype 082 test gauge is glass. Non-glare glass is optional. Acrylic windows, also optional, are more resistant to impact breakage than glass windows. Safety glass, also optional, will not fracture into many pieces as will ordinary glass. Window for ype 084 is polycarbonate. Rings: he ring, which retains the window, is threaded, bayonet (cam) or hinged, depending upon case type. All ype 082 windows have a gasket to protect the internal mechanism from outside environments.
