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.
