GP140 Series Diaphram Seal

GP140-Series-Diaphram-Seal

PROCESS PRESSURE GAUGE CHEMICAL SEALS/ ISOLATORS

The GP1000 Series Is 3D Instruments’ rugged product line of gauge protectors and diaphragm seals. All seals are precision micro-matched at the 3D factory for accuracy and reliability. Because 3D’s Direct-Drive Bourdon Element has a fluid path volume of only 2 cc or less, it has about 20 times less volume than a standard C-type. The resultant displacement of 0.88 cc or less allows 3D to offer gauge protection unmatched in the industry, while maintaining accuracy and sensitivity better than any other gauge and seal combination available.


GP140 METALLIC DIAPHRAGM SERIES

Features

Welded body of 316 stainless steel or Hastelloy C (other materials available)


Metallic diaphragm of 316L stainless steel or Hastelloy C (other materials available)


Available in 1/4” or 1/2” process connections


Available with process flush port


A more compact design than industry standard seals (1-1/2 inch hex, max.)


Low effects on accuracy: 1% on a 100 psi gauge* 0.1% on a 1000 psi gauge. *Can be custom spanned for greater accuracy (models KT and KET).


Low temperature effects: (Models KT and KET) 0.2% per 10 deg. F on a 100 psi gauge. 0.03% per 10 deg. F on a 1000 psi gauge.


Applications

Highly corrosive chemical environments


Highly viscous processes.


Processes prone to plugging or fouling.


Very high pressure pulsations.


Service pressures 100-2000**psi.


Not recommended for services below 100 psi without custom span adjustment.
