Dale S. Davis - Prior Lake MN
Mark C. Fandrey - Eden Prairie MN
Roger L. Frick - Hackensack MN
Robert C. Hedtke - Young America MN
Richard L. Nelson - Chanhassen MN

Mark S. Shumacher - Minneapolis MN
Assignee:

Rosemount Inc. - Eden Praire MN
International Classification:

G01L 900
US Classification:

73753
Abstract:

A scalable process transmitter architecture includes a unitized sensor module and an optional scalable transmitter. The sensor module has a sensor output that is configurable which can connect locally to a scalable transmitter module to form a transmitter, or can be wired directly to a remote receiver. The scalable transmitter can mount on the unitized sensor module and generates a scalable output for a remote receiver. The transmitter module can provide more advanced features for specific applications.

Weston Roper - St. Louis Park MN
Assignee:

Rosemount Inc. - Eden Prairie MN
International Classification:

G01L 900
US Classification:

73753
Abstract:

A pressure sensor module and method for pre-installation without a converter module. The pressure sensor module is hermetically sealed and can remain undamaged in an installation environment without a converter module. The pressure sensor module can be assembled later with a converter module in the installation environment. The pressure sensor module includes an isolator, a pressure sensor and a circuit that provides a bus for energization, control and a digital pressure output. The bus is connected to contacts in an insulating feedthrough. An integrally formed hermetic external support structure surrounds the pressure sensor and circuit. The hermetic external support structure has a threaded process fluid inlet around the isolator, and a threaded support sleeve supporting the feedthrough.

Filed:

Sep 21, 2000
Appl. No.:

09/667399
Inventors:

Steven M. Behm - White Bear Lake MN
William B. Krueger - Bloomington MN
Kelly M. Orth - Apple Valley MN
Jeffrey C. Brekken - Richfield MN
Assignee:

Rosemount Inc. - Eden Prairie MN
International Classification:

G01L 1904
US Classification:

73708
Abstract:

A pressure transmitter with a transmitter housing having an outer wall providing thermal resistance. The outer wall extends from an isothermal island at a first end to a heat sink island at a second end. The isothermal island includes a fluid inlet, and pressure and temperature sensors. The heat sink island includes a primary heat load device that is heat sunk to an outer shell of an electrical connector. The connector contacts carry a current controlled by the transmitter, and a portion of the current is conducted by a primary heat load device. A circuit board controls the current to represent the pressure. A high accuracy, temperature compensated current output represents pressure.

International Classification:

G01L 900
US Classification:

73753, 73717, 73700
Abstract:

A pressure transmitter with a hermetically sealed housing surrounding a cavity that is filled with a gas that is free of integrated circuit contaminants. A sensor circuit including an integrated circuit is placed in the cavity and a gas fill port on the housing is sealed. The sensor circuit is electrically adjustable from outside the pressure transmitter and the integrated circuit is protected from contaminated atmospheres outside the pressure transmitter.

Assignee:

Rosemount, Inc. - Eden Prairie MN
International Classification:

G01L 708
US Classification:

73715
Abstract:

A pressure transmitter with a fluid isolator that includes a sensor tube and a fill tube that have âDâ shaped ends that connect together in a port internal to the transmitter. The shaped ends can be brazed into the port for sealing. Fitting both the sensor tube and the fill tube in the same port provides a low cost isolator with reduced isolator liquid volume. The fluid isolator has an isolator diaphragm with a central diaphragm region overlying a central backing plate that includes a annular groove. The annular groove avoids slow response of the isolator after an overpressure condition.
