Installation
Prior to pressure gauge installation, the following conditions should be
considered: temperature, humidity, vibration, pulsation, shock, and other
climatic and environmental conditions of the application, as well as the
potential need for protective accessories and/or special installation
requirements.
Always use a wrench on the gauge socket when installing a NOSHOK pressure
gauge into position; never use force on the gauge case to tighten into
position. This may result in a loss of accuracy, excessive friction and/or
mechanical damage to the measuring element and case of the NOSHOK pressure
gauge. When surface or panel mounting a gauge, be sure the surface is flat and
the panel cutout and/or the mounting hole configuration is correct (please
refer to the NOSHOK Pressure Measurement Solutions catalog for these
specifications). If the surface is uneven or the panel cutout is larger than
the gauge’s diameter, use an adapter ring to remove mounting strain and/ or
adapt the gauge to the larger diameter panel cutout. When connecting a gauge
to a rigid pipe service,
use flexible tubing where possible as a connector to eliminate plumbing
strain. Rapid pressure pulsation and extreme mechanical vibration may be
damaging to some NOSHOK pressure gauge movement gearing, bushings, and
linkage. In extreme cases, steps should be taken to dampen these forces. In
pressure ranges over 600 psi, a NOSHOK orifice is recommended for pulsation
dampening, but in extreme pulsation applications a NOSHOK Piston Type Pressure
Snubber may be required.
When installing a gauge into a corrosive situation, be sure to select a
pressure gauge or pressure gauge and diaphragm seal combination suitable for
your application. Gauges to be used on high temperature service should have a
five foot or longer leg of pipe or tubing connecting the gauge to dissipate
heat and protect the gauge measuring element from damage. A gauge to be used
on steam pressure service should be installed with a water filled NOSHOK
pigtail steam syphon between the gauge and the steam line.
Maintenance
Apart from occasional calibration, NOSHOK pressure gauges require little or no maintenance. Some applications may be more aggressive than others, resulting in an increased frequency in the need for calibration. The environmental limitations for the specific NOSHOK pressure gauge series should be observed in all cases, and gauges applied in situations outside these requirements may result in premature wear and/or failure of the gauge.
Warranty
All NOSHOK pressure gauges carry a one or three year warranty. NOSHOK warrants for three years our 300, 500, 502, 660, 760, and 900 series liquid filled pressure gauges to be free from defects in materials and workmanship, to remain within the cataloged accuracy and performance specifications, and to maintain the integrity of the hermetically sealed case preventing leakage. NOSHOK warrants for one year our 100, 200, 400, 402, 640, 740, and 800 series dry pressure gauges. Certain limitations do apply; for more information please refer to the NOSHOK Pressure Measurement Solutions catalog.
CAUTION
Operating conditions including, but not limited to, system pressure, media
compatibility and ambient conditions must be considered when selecting gauges
and accessories. Improper selections and use of gauges could possibly cause
gauge failure and lead to possible property damage or person in. jury Refer to
American National Standard ANSI B40.1 for the correct selection and use of
gauges. A copy of this standard may be obtained from the American Society of
Mechanical Engineers, United Engineering Cente, r 345 East 47th Street, New
York, NY 10017.
WARNING
Glycerin or silicone could result in a spontaneous chemical reaction or
explosion when combined with strong oxidizing agents including (but not
limited to) chlorine, hydrochloric or nitric acid and hydrogen peroxide. Do
not use Glycerin or silicone filled gauges or accessories in these types of
service. Consult factory for application assistance. In keeping with and for
the purposes of product and/or manufacturing improvements, NOSHOK, INC.
reserves the right to make design changes without prior notice.
