Patent number: 10996114Abstract: Apparatus and associated methods relate to measuring temperature of a fluid within a hydraulic vessel using a temperature probe that has an annular recess circumscribing a projecting sensor tip. The annular recess is configured to permit fluid flow into an aperture region of a vessel wall through which the temperature probe contacts the fluid within the hydraulic vessel. Because the temperature probe projects from the annular recess within the aperture, a net projection dimension, as measured in a projection direction from an interior surface of the vessel wall proximate the aperture to a sensor, is less than a gross projection dimension, as measured in the projection direction from a bottom of the annular recess to the sensor tip. In some embodiments, this configuration advantageously improves a ratio of thermal conductivity between the fluid and the temperature probe and thermal conductivity between the temperature probe and a sensor housing.Type: GrantFiled: June 21, 2018Date of Patent: May 4, 2021Assignee: GOODRICH CORPORATIONInventors: Venkata AnilKumar Mothe, Ramesh Annamareddy, Richard William Phillips

The flexible wall is arranged in the flow channel (3) in thermal contact with the fluid flowing therein, and the flexible wall is adapted to conduct heat between the flow channel (3) and the inner cavity (5). Thereby the temperature of the charge fluid (6) adapts to the temperature of the fluid flowing in the flow channel (3), and the pressure in the inner cavity (5) is determined by this temperature. A first wall part (7, 14) and a second wall part (9, 16) are arranged at a variable distance from each other, said distance being defined by a differential pressure between the pressure of the charge fluid (6) and the pressure of the fluid flowing in the flow channel (3), i.e.Type: GrantFiled: August 18, 2009Date of Patent: July 22, 2014Assignee: Danfoss A/SInventors: Asbjoern Leth Vonsild, Claus Thybo, Leo Bram, Jakob Spangberg

Publication number: 20140151908Abstract: In accordance with the present invention, there is provided a steam desuperheater which is integrated into a steam line. The steam desuperheater comprises a segment of steam pipe having one or more spring loaded spray nozzles attached thereto. Installed within the interior of the steam pipe of the desuperheater is a liner. The desuperheater is also provided with a steam flow measurement sub-assembly comprising a differential pressure transmitter including a pair of pressure gauges which are operatively connected to respective ones of a first pressure tapping which is formed in the steam pipe before the liner, and a second pressure tapping which is formed in the liner. The measurement of the differential pressure allows for a determination of steam flow through the desuperheater.Type: ApplicationFiled: June 10, 2013Publication date: June 5, 2014Inventor: Tord Forslund

Patent number: 8672539Abstract: A multiple sensor fiber optic sensing system. A method of sensing distributed temperature and at least another property in a well includes the steps of: interconnecting an optical switch to an optical fiber which extends along a wellbore in the well; operating the optical switch to optically connect the optical fiber to an interferometric measurement system; and operating the optical switch to optically connect the optical fiber to a distributed temperature measurement system. Another method includes the steps of: installing an optical fiber along a wellbore in the well, the optical fiber being a first distributed temperature sensor, the installing step including providing a substantial length of the optical fiber proximate a second sensor which senses the well property; and calibrating the second sensor using a temperature sensed by the first sensor in the substantial length of the optical fiber.Type: GrantFiled: June 8, 2009Date of Patent: March 18, 2014Assignee: Halliburton Energy Services, Inc.Inventor: Neal G.

Patent number: 8672541Abstract: A temperature sensor (100) includes a heat-sensitive element (21) having a thermistor sintered-body (22), an insulating support (31), an insulation sheath (41) and a housing tube (11). The insulating support (31) is in contact with the rear end of the heat-sensitive element (21) and the insulation sheath (41) is in contact with the rear end of the insulating support (31). The housing tube (11) accommodates the heat-sensitive element (21), the insulating support (31) and the insulation sheath (41). The housing tube (11) includes a sheath accommodation portion (14) which accommodates the insulation sheath (41) and a distal accommodation portion (13). The distal accommodation portion (13) is located toward the distal end of the housing tube (11) with respect to the sheath accommodation portion (14), is smaller in outside diameter than the sheath accommodation portion (14), and accommodates at least half of the insulating support (31) as measured from the axially distal end of the insulating support (31).Type: GrantFiled: August 18, 2011Date of Patent: March 18, 2014Assignee: NGK Spark Plug Co., Ltd.Inventors: Masamichi Ito, Koji Matsuo, Satoshi Ishikawa

The shroud wall is comprised of an inner skin and an outer skin which enclose a second cavity therebetween. A temperature sensor mounted in the first cavity. In use, fluid flow is received into the first cavity, passes through at least one aperture in the inner skin into the second cavity and thence passes out of the shroud through at least one aperture in the outer skin. Beneficially, heat conduction across the inner skin is minimal.Type: ApplicationFiled: July 10, 2013Publication date: February 6, 2014Inventors: Steven John THORPE, Clare BONHAM, Mark Nicholas ERLUND

Publication number: 20140023112Abstract: A method for determining a value of a parameter of an object or an environment includes positioning a device having a balanced circuit in or on an object or within a particular environment, wherein the balanced circuit comprises elements which are operationally sensitive to changes in a parameter of the object or the environment. The method further includes measuring a common mode signal of the balanced circuit and determining, from the common mode signal, a value of the parameter. An exemplary implementation of the method includes determining temperature using a resistive sensor having a Wheatstone bridge circuit with two variable resistors and two fixed resistors. Embodiments of systems and devices configured to employ such methods are provided, particularly medical probes, electronic signal monitoring devices, and systems employing such devices.Type: ApplicationFiled: July 18, 2012Publication date: January 23, 2014Applicant: MILLAR INSTRUMENTSInventors: Huntly D.
