Filed:

Oct 18, 2011

Appl. No.:

13/275652

Inventors:

Mark L. Muldowney - Chalfont PA, US
Keith Sayuk - Harleysville PA, US

Assignee:

HONEYWELL INTERNATIONAL INC. - Morristown NJ

International Classification:

H05K 5/00
H05K 13/00
G06F 1/16

US Classification:

361752, 36167931, 295921

Abstract:

An intrinsically safe serviceable transmitter apparatus and method includes a sensor module composed of at least a sensor and a sensor electronic module in order to transmit an electrical signal from the sensor module to a dual cap electronic housing module. The dual cap electronic housing module includes an electronics module, a terminal block, and an intrinsically safe circuit and noise rejection unit. The electronic housing module includes a meter cap and a field-wiring cap in order to permit a user to open either side of the transmitter housing in an intrinsically sale environment. Once open, a local integral meter can be added to calibrate and reconfigure the apparatus and/or to replace a communications board. The terminal block located in a field-wiring compartment acts as an intrinsically safe barrier for the rest of the transmitter electronics and simplifies board replacement.

International Classification:

G01F 23/00
G01F 23/18

Abstract:

A fluid level transmitter combination for placement on a tank having ≦2 tank apertures. A first and second flange provides a first, second and third flange aperture over the tank aperture(s). A temperature sensor over the first flange aperture senses a temperature. A first pressure sensor over the second flange aperture senses a first pressure. A second pressure sensor senses a second pressure. A processor is coupled to the output of the second pressure sensor that implements a compensated fluid level determination algorithm using the temperature, first pressure, and second pressure to generate a compensated fluid level measurement for the process fluid. A transmitter is coupled to an output of the processor.

International Classification:

G01S 13/10
G01S 7/41
G01F 23/284

Abstract:

An obstruction marking method includes generating a first echo curve using an electronic level gauge (ELG) coupled to a tank from a first reflected signal (echo signal) received when a material in the tank is at a first level. The ELG includes a radar-based obstruction detection algorithm stored in a memory coupled thereto. A processor implementing the obstruction detection algorithm identifies at least a first feature in the first echo curve to provide at least one suspected obstruction along with its position (first feature position). A second echo curve is generated from a second reflected signal when the material is at a second level. A third echo curve is generated from a third reflected signal when the material is at a third level. The suspected obstruction at the first feature position is stored in the memory as a verified obstruction with its first feature position.

G01F 23/14

Abstract:

A fluid level transmitter combination for placement on a tank having ≦2 tank apertures. At least one flange provides a first, second and third flange aperture over the tank aperture(s). A temperature sensor over the first flange aperture senses a temperature. A first pressure sensor over the second flange aperture senses a first pressure. A level transmitter extends through the third flange aperture for transmitting a pulse signal into the process fluid or at its surface and receiving a pulse echo or a second pressure sensor senses a second pressure. A processor is coupled to the level transceiver or to an output of the second pressure sensor that implements a compensated fluid level determination algorithm using the temperature, first pressure, and pulse echo or second pressure to generate a compensated fluid level measurement for the process fluid. A transmitter is coupled to an output of the processor.
