Red Flag This Post Please let us know here why this post is inappropriate. Before conducting the accuracy test, subject b40.1000 gauge to a pressure equal to the maximum indicated pressure or vacuum. Internal pressure containing parts shall be joined by welding or nicrobrazing. The difference in readings at each test point between room temperature and the maximum operating temperature is the high temperature error.

Are you an Engineering professional? The pressure medium used for aame shall maintain the required cleanliness level of the gauge under calibration or calibration verification.

The above diagrams of various types of elastic elements used in pressure gauges are schematic and not intended to g40.100 design detail. Standard instrument connections are 1? Compressed Gas Association, Inc.

ASME B Archives – Impact Industrial Sales

It is used to reduce the effect of pressure fluctuations or to control flow from a pressure element that has failed in service, or both. The full-scale pressure of the gauge selected should be approximately 2 times the intended operating pressure.

Conformance inspection shall be performed at the place of manufacture. Coatings may have been applied for other purposes and may have voids that allow corrosion.


Pressure Gauge ASME B

Weld filler material is generally asne to the material of the lower housing [see Fig. The user should inform the gauge supplier of the installation conditions so that the appropriate element materials can be selected.

All items shall meet all requirements of section C Depending on the accuracy and the range of the gauge, hazardous pressure may remain in the tank even though the gauge 4b0.100 indicating zero pressure. Display Dial Thermometers Digital Indicators.

8008A Pressure Gauge meets EN837-1 and ASME B40.100 standards.

The consequence of reuse without cleaning can range from contamination to explosive failure. Threaded and flanged lower housings may be provided with a flushing connection, permitting the user to purge the area below the diaphragm without removing the seal from the process line. The sample shall then be inclined 60 deg to the right, left, front, and back. A zero graduation or numeral, or both, shall not be permitted at the stopped pointer position on gauges using a stop pin or internal stops that prevent free pointer motion to the actual zero pressure position.

Specific applications for pressure gauges exist where hazards are known. Fill fluid is placed in the reservoir. Asem first symbol designates the type of connection fitting.

It should not be assumed that every test or safety procedure or method, precaution, equipment, or device is contained in this Appendix, or that abnormal or unusual circumstances may not warrant suggesting further requirements or additional procedures.


The diaphragm is an integral part of a standard flange and installed to be flush with the flange sealing face. A lot consists of all gauges of the same part identification number bb40.100 are manufactured at one time.

If reusing a diaphragm seal is required, all guidelines covered in this Standard, relative to applications of diaphragm seals, should be followed in the same manner as when a new diaphragm seal is selected asmw para.

It is generally accepted that a solid front case per para.

There should be mutual agreement between user, supplier, or manufacturer, or some combination, regarding the applications and the ssme variations. Conduct the accuracy test within 10 minutes.

The purpose of this construction is to exclude ambient corrosives or protect the internals from damage caused by severe vibration or pulsation. In addition, consideration should be given to environmental effects such as corrosion of the external portions of the diaphragm seal.

ASME B40.100-2005 Pressure Gauges and Gauge Attachments

Gauges shall have an accuracy of Grade B or better see Table 1. Applying vacuum to low pressure instruments may damage the instrument. If a diaphragm capsule is used, a mid-housing may not be required [see Fig.
