Applications:
Packing:
It measures gauge pressure, which is pressure relative to atmospheric pressure, using Emerson’s Coplanar™ platform for flexible integration.
It supports a wide span—from 25 inH₂O to 2000 psi (1.72 mbar to 137.89 bar), depending on the selected sensor range.
It offers ±0.04% of span accuracy, with a 150:1 turndown ratio, ensuring precise performance across a wide range of applications.
The 3051CG uses a Coplanar flange, allowing direct mounting to manifolds or remote diaphragm seals.
Yes, it is SIL 2/3 certified per IEC 61508, making it suitable for Safety Instrumented Systems (SIS).
It features:
Yes. Models with a graphical LCD support local configuration via external buttons—even in hazardous areas.
