Installation & Maintenance Guide

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 at and the panel
cutout and/or the mounting hole conguration is

correct (please refer to the NOSHOK Pressure
Measurement Solutions catalog for these
specications). 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 exible 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
orice 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 ve 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 lled 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

specic 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 lled pressure gauges to be free from defects in

materials and workmanship, to remain within the

cataloged accuracy and performance specications,

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 lled gauges or accessories in these types of

service. Consult factory for application assistance.
