Gauge Protectors and Diaphragm Seals (GP1000 Series)

Manufacturer: 3D Instruments

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 standard C-type. The resultant displacement of a 0.08 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

Applications:

Highly corrosive chemical environments.

Highly viscous processes.

Processes prone to plugging or fouling.

Very high pressure pulsation's.

Service pressures 100-2000**psi.

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

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 & KET).

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