European Committee for Standardization? It is expressed as a percentage of span.
Wish list – Documents 0 There are currently no documents on your wish list. At the conclusion of the test, accuracy shall be in accordance with Table 1, accuracy Grade 1A. Hg Unit feet of b04.100 water Definition in. Above this pressure, 1? Gauges used on regulators are usually size 11? The sample shall be positioned so that the dial faces the operator.
Appropriate additional considerations are discussed. Gauges used on oxygen regulators shall comply with cleanliness Level IV or better. This listing is intended as an outline only with paragraph references to detailed descriptions.
At each test assme the gauge under test shall be read, lightly tapped, and then read again. Home Products Pressure Gauges Back to overview.

An instrument may be filled by attaching it to a manifold and applying vacuum to the connection until all air is removed. Wsme vacuum to low pressure instruments may damage the instrument. Additional information is outlined in Nonmandatory Appendix A. Impact and abrasive environmental conditions, especially temperature and corrosive atmosphere, must be carefully considered to determine the type of plastic best suited for the application. In many instances, requirements for design, construction, and use of gauges for these applications are specified by state or federal agencies or Underwriters Laboratories, Inc.
DO NOT interchange gauges from one gas application to another. Table C-4 shows the ranges ssme range designators for refrigerant pressure gauges. The diaphragm is the most critical component in the assembly.
Removal of the connection between the mid-housing and the lower housing permits access to the process side of the diaphragm without loss of the seal between the upper housing and the diaphragm. Standards for pressure, weight, density, and linear dimensions used in manufacturing and calibrating the test instruments shall conform to equivalent measuring standards that have been calibrated at NIST and shall have a documented path to NIST.
The sample shall then be inclined 60 deg to the right, left, front, and back. The gauge shall not change its appearance.
Job opportunities FAQ Unit calculator. The dial may be graduated in units of pressure, temperature, flow, or other measurements corresponding to the transmitter input.
The error can be determined from the data obtained in the two pressure cycles and is equal to the maximum error at each test point, in either direction, after tapping. The following are types of temperature: The gauge under test shall be secured to the vibration table in the same manner that it will be secured in service.
It will also reduce the possibility of disengagement of the movement mechanism caused by the inertial effect of sudden pressure changes. Both signs and words should not appear on the same scale. This test is applicable only to new gauges and is not intended for gauges that have had their useful life reduced.
Consideration must be made of the possibility of health hazards associated with the handling of fill fluids. Common process connections are described in paras. Materials readily susceptible to sea water corrosion damage for example, brass, aluminum, beryllium copper, mild steel shall not be used for threaded fasteners or washers.
Accuracy Grade Definitions | Miljoco
Before conducting the accuracy test, subject the gauge to a pressure equal to the maximum indicated pressure aeme vacuum. To receive your download link via e-mail, enter your address here: For a given temperature change, the percentage of error noted on the gauge is a function of the range or span b40.1000 the gauge. The pressure instrument and top housing assembly may be removed from the bottom housing as a unit, without loss of fill fluid this should be done only when there is no pressure in the process line.
When black light radiation methods are employed, the manufacturer should ascertain that the solvent used will dissolve all hydrocarbons that could be present and that all hydrocarbons are detectable and fluoresce n40.100 black light. Conformance inspection shall be performed at the place of manufacture.
1017 Pressure Gauge
A corrosive medium may dictate use of an element material having less than optimum properties. The pointer shall rotate clockwise for increasing positive pressure and counterclockwise for increasing negative pressure. Even a minute amount of hydrocarbon can be hazardous in the presence of oxygen. Azme spacing and displaying of the numerals marked on the gauge dial may vary for aesthetic reasons, provided that at least three numerals are displayed.
Indicating pointers shall be a nonreflective black with white background dials or white when dials have black backgrounds. Same hysteresis value is lower if the pressure excursion is less than full scale. Where possible, scale, numeral, and graduation increments should follow the format: Two gauges of each design, size, range, and elastic element style shall be subjected to the qualification inspection.
The user should inform the supplier of all conditions pertinent to the application and environment so that the supplier can recommend the most suitable gauge for the application. Aeme methods may be employed to fasten the upper, mid, and lower housing together.
Mounting holes or studs are used for flush and surface-mounted gauges. The pressure connection shall be sealed to prevent penetration into the elastic element. The capillary connection is on the side of the seal, enabling use in areas where space is limited or restricted on the outside of the vessel.
