Patent number: 10656039Abstract: An apparatus includes a sensor body, a sensor configured to measure differential pressure, and first and second pressure inputs in or on the sensor body. The pressure inputs are configured to provide multiple input pressures to the sensor. Each pressure input includes a barrier diaphragm configured to move in response to pressure and an overload diaphragm configured to limit movement of the barrier diaphragm. The overload diaphragm is also configured to exert a preload force against the sensor body. The overload diaphragm of each pressure input may include multiple convolutions. Bases of the convolutions may be configured to provide the preload force, and tops of the convolutions may be separated from the sensor body by gaps. Tops of the convolutions that are non-adjacent may be configured to provide the preload force, and tops of the convolutions between the non-adjacent convolutions may be separated from the sensor body by gaps.Type: GrantFiled: June 29, 2017Date of Patent: May 19, 2020Assignee: Honeywell International Inc.Inventors: George Hershey, Richard D.

Patent number: 10345178Abstract: An apparatus includes a header containing a sensor configured to measure pressure and a sensor body connected to the header, where the sensor body and the header form a pressure vessel configured to receive an input pressure. The header is connected to the sensor body such that the input pressure received on an inner surface of the header is substantially equal to the input pressure received on an outer surface of the header. A lowest connection point of the header to the sensor body may be located at or above a highest point at which the input pressure extends into the header. A lower portion of the header may be unconnected to the sensor body and extend into an interior volume of the sensor body. The header may include a vent configured to expose the sensor to atmospheric pressure or a lower-pressure input pressure.Type: GrantFiled: June 29, 2017Date of Patent: July 9, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: George Hershey, Richard D.

Patent number: 9581483Abstract: A tank overflow protection system and method for measuring process temperature and pressure utilizing one or more piezoresistive pressure transmitters. The piezoresistive pressure transmitter includes a differential pressure sensor and a temperature sensor. Data from the piezoresistive pressure transmitters can be digitally communicated via a cable. The pressure transmitters convert signals indicative of temperature and pressure to a digital value and transmit the signals to a main processor printed wire assembly for final compensation, diagnostics, and transmission to a distributed control system. A differential pressure can be calculated by subtracting two digital pressure measurement values. The temperature measurement can be employed to calculate any changes in density for a user-defined reference value.Type: GrantFiled: March 23, 2012Date of Patent: February 28, 2017Assignee: Honeywell International, Inc.Inventor: George Hershey

Patent number: 9347847Abstract: A pressure transmitter includes at least one impulse line for coupling a fluid pipe or tank to a pressure sensor that measures a process pressure of a process fluid, a temperature sensor measuring an ambient temperature, and a processor accessing baseline data for the process pressure and ambient temperature. The processor implements an automatic impulse line plugging diagnostic (ILPD) algorithm stored in memory. The processor runs the ILPD algorithm implementing utilizing process measurements including a process pressure from the pressure sensor and an ambient temperature from the temperature sensor, comparing a magnitude of the process pressure to a baseline pressure predicted from the baseline data corresponding to the ambient temperature, and uses results of the comparing to determine whether the impulse line is plugged. The comparing can involve comparing a process pressure change to a baseline pressure change predicted corresponding to an ambient temperature change.Type: GrantFiled: August 19, 2014Date of Patent: May 24, 2016Assignee: Honeywell International Inc.Inventor: George Hershey
