Apparatus for coupling a transmitter to process fluid
First Claim
1. A transmitter of the type used in the process control industry for sensing a process variable of a process fluid, the transmitter comprising:
- a transmitter body having a sensor coupling;
a sensor extension coupled to the sensor coupling, the sensor extension having a sensor coupling face and an opposing face opposite the sensor coupling face;
a first flange interface having a process face which connects to the process and a sensor coupling face which mates with the sensor, the first flange interface including a passageway which couples the process fluid to the sensor coupling face;
a second flange interface positioned adjacent the opposing face of the sensor extension whereby the sensor extension is positioned between the first and second flange interfaces; and
a shut off valve coupled to the passageway of interface to selectively block coupling of process fluid to the sensor coupling face.

Abstract
A transmitter of the type used in the process control industry includes a sensor for sensing a process variable and a transmitter body having a sensor coupling. A sensor extension couples to the sensor coupling and includes a sensor coupling face. A first flange interface has a process face which provides a process connection and a sensor face which provides a sensor connection. A passageway couples the process connection to the sensor connection. The first flange interface is coupled to the sensor extension by a coupling mechanism. The sensor extension and the first flange interface may be moved throughout a range of positions relative to one another.
