Electronic pressure instruments must be selected in accordance
with industry codes and safety practices to avoid the possibility of
misuse or misapplication which could result in personal injury or
property damage. Personnel responsible for selection and instal-
lation should also be familiar with the safety recommendations of
ASME B40.1, that apply to elastic pressure elements and their
application in general and specific services. ANSI B40.1 is avail-
able from:
ASME
345 East 47th Street
New York, NY 10017
Pressure – Select a range so that the maximum applied pres-
sure will never exceed the upper range limit.
Vibration – Excessive vibration could cause loosening of
components resulting in loss of instrument accuracy
or failure to provide valid data.
Pulsation – Excessive pressure pulsation could result in fatigue
failure of the pressure element.
Temperature – Operation of the instrument in an environment
where temperatures are in excess of design ratings
may result in loss of accuracy and failure.
Process – Pressure boundary materials must be resistant to
the process media. Failure to assure compatibility
may result in pressure sensing element deterioration
or failure. Instruments used on high pressure gas,
or potentially hazardous service, such as oxygen
should be carefully selected in accordance with the
recommendations of ANSI B40.1.
Hazardous Location – Only approved explosion proof or intrin-
sically safe instruments should be used in hazard-
ous locations.
Electro-Magnetic Interference – Instruments should not be used
in locations where EMI/RFI conditions exceed
design ratings, to avoid erroneous performance.
