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 CONDI-

TIONS CORROSIVE TO ANODIZED ALUMINUM, SUBJECT TO SPRAY

OR DRIPPING, OR USE IN A HIGH VIBRATION ENVIRONMENT. THE

TRANSDUCER IS VERY 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 sensi-

tivity. The wrench flat on the pressure port should be used when installing

the positive pressure fitting.

See page 26 for transducer specifications and media compatibility.
