7.0 Installation of pressure fittings for the manometer
Your transducer is designed for most accurate operation when subjected
to pressures within the designated pressure range. Refer to catalog bulletin
specifications for proof pressure limits. Subjection to excessive pressure voids the
warranty. DO NOT OVERPRESSURE.
CAUTION: DO NOT SUBMERGE IN LIQUIDS, USE IN AMBIENT CONDITIONS
CORROSIVE TO ANODIZED ALUMINUM, SUBJECT TO SPRAY OR DRIPPING, OR
USE IN A HIGH VIBRATION ENVIRONMENT. THE TRANSDUCER IS SLIGHTLY
SENSITIVE TO ACCELERATION IN THE PRESSURE FITTING AXIS (SEE APPLICABLE
SPECIFICATIONS BULLETIN FOR ACCELERATION RESPONSE SPECIFICATIONS).
Standard thread sealants such as Teflon pipe tape generally are satisfactory. For
the most sensitive pressure ranges, excessive high torquing of a metal pressure
fitting may cause slight zero shift which may be trimmed out using the "OFFSET"
adjustment. Use of a plastic fitting often shows no noticeable zero shift. The
torquing effect does not appreciably affect linearity or sensitivity. The wrench flat
on the pressure port should be used when installing the positive pressure fitting.
