Abstract
Official abstract text for this publication.
A process variable transmitter for measuring a pressure of a process fluid includes a sensor module, a pressure inlet formed in the sensor module, an isolation diaphragm positioned in the pressure inlet, a pressure sensor and an isolation tube containing a fill fluid to convey a process fluid related pressure from the isolation diaphragm to the pressure sensor. A hydrogen getter material is positioned in contact with the fill fluid between the isolation diaphragm and the pressure sensor to remove hydrogen from the fill fluid.
First claim
Opening claim text (preview).
What is claimed is: 1. A process variable transmitter for measuring a pressure of a process fluid comprising: a sensor module having a housing and a base; at least one pressure inlet formed in the base of the sensor module and coupleable to a process fluid related pressure; an isolation diaphragm positioned at the at least one pressure inlet in the base; a pressure sensor spaced apart from the isolation diaphragm; an isolation tube extending through the base and containing…
