Pressure sensor assembly
First Claim
Patent Images
1. A pressure sensor assembly configured to measure pressure of a process fluid, comprising:
- an elongate pressure sensor having a proximal connection end and a distal pressure sensing end;
a sensor mounting block having a first side, an opposed second side and an opening extending therebetween, the elongate pressure sensor extending through the opening;
a seal between the mounting block and the elongate pressure sensor; and
a protective element formed to the elongate pressure sensor and the seal which covers the seal and at least portions of the elongate pressure sensor to prevent corrosion of the bond due to contact with the process fluid, the protective element configured to transfer an applied pressure to the pressure sensor.

Abstract
A pressure sensor assembly includes an elongate pressure sensor mounted to a sensor mounting block. A protective element covers the elongate pressure sensor to prevent the pressure sensor from contacting process fluid.

13. A pressure sensor assembly configured to measure pressure of a process fluid, comprising:
-
a corrosion resistant mounting block;
an elongate pressure sensor, the pressure sensor having a proximal connection end and a distal pressure sensing end;
an elongate sheath formed to the elongate pressure sensor of a corrosion resistant material open at a proximal end and closed at a distal end carrying the elongate pressure sensor therein, the sheath generally conforming to a shape of the pressure sensor to prevent contact of the elongate pressure sensor element with the process fluid and configured to transfer applied pressure to the pressure sensor;
a packing material between the sheath and the pressure sensor configured to transfer a pressure applied to the sheath to the pressure sensor; and
a bond coupling the elongate sheath to the mounting block, the bond of a corrosion resistant material. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
