NOSHOK Installation & Maintenance Guide

Pressure Gauge Series 100, 200, 300, 400, 500, 600, 700, 800 and 900

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 Gauge catalog
NK95G for these specifications). If the surface is uneven or
the panel cutout is larger than the gauges 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.

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,
600, and 700 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, 600, 700, 800,
and 900 series non-liquid filled pressure gauge. Certain
limitations do apply; for more information please consult
page three of the NOSHOK Pressure Gauges catalog
(NK95G).

questions.

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

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 injury. 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 Mechani cal Engineers, United Engineering Center, 345
East 47th Street, New York, NY 10017.

WARNING:

Glycerine 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 glycerine or silicone filled gauges or accessories in these types of service. Consult factory for application
assistance.
