  • Patent number: 9857289
    Abstract: Fouling of or damage to an electromagnetic radiation-transparent window can preclude one from obtaining satisfactory images with an image acquisition unit, such as a camera. Certain types of environments may be particularly prone toward promoting fouling or damage, and manual cleaning or repair of an electromagnetic radiation-transparent window may be difficult in some circumstances. These issues may be particularly prevalent when imaging drill cuttings and other solids obtained from a wellbore due to the complex sampling environment in which these solids are often disposed.

    Abstract: An apparatus and method for flud flow measurement are provided. The apparatus includes a first thermistor; a second thermistor; a first deflecting member configured to shield the first thermistor from fluid flowing in a first direction; a second deflecting member configured to shield the second thermistor from fluid flowing in a second direction where the second direction is substantially opposite the first direction; and a circuit in electrical communicati with the first thermistor and the second thermistor. The circuit includes a comparator for comparing a first signal from the first thermistor to a second signal from the second thermistor.

  • Patent number: 7156552
    Abstract: A temperature sensor system includes a body and window arrangement. The body defines an air intake and is flush mounted to a mobile platform having a boundary layer. The window arrangement is integrated into the body and transfers a first signal and receives a second signal. The second signal represents energy from the first signal that is reflected by air particles beyond the boundary layer. The second signal is processed to determine a temperature beyond the boundary layer. The air intake receives air particles, transfers a first set of the air particles to a first air vent into the mobile platform, receives the first set of the air particles from a second air vent from the mobile platform, vents the first set of the air particles, and vents a second set of the air particles that bypass the first air vent.

  • Patent number: 7114847
    Abstract: The invention relates to a total temperature probe for an aircraft and to a method of determining temperature by means of such a probe. The total temperature measurement probe comprises a base, an external face of which is intended to be mounted so as to be substantially coplanar with a skin of the aircraft, and a mast that projects from the base and supports an active part of the probe. The probe furthermore includes several temperature sensors placed on, the external face of the base and distributed around the mast. The method consists in determining the total temperature of the air surrounding the probe on the basis of the temperature measurement carried out in the active part (4) of the probe and on the basis of the maximum difference that exists between the measurements made by the temperature sensors.

  • Patent number: 7056013
    Abstract: A temperature sensor arrangement (100, 300) includes a sensor cavity (150), a temperature sensing element (330) being positioned along a center line (140, 340) of the sensor cavity (150) and generating a signal indicating temperature of air flowing thereto, and a generally cylindrical outer casing (105, 305) surrounding the sensor cavity (150). In one embodiment, the outer casing (105) includes a pattern of flow passages (110) for allowing air flow to the temperature sensing element (330) in the sensor cavity (150), the flow passages (110) being angled such that there is no direct line of air flow from an exterior of the outer casing (105) to the sensing element (330). In another embodiment, the flow passages (310) are arranged in an offset pattern relative to a center line (340) of the housing cavity (150), such that there is no direct line of air flow from an exterior of the outer casing (305) to the sensing element (330).

  • Patent number: 6974250
    Abstract: The present invention relates to providing a temperature sensor that is mountable on an aircraft and includes a thermometer or temperature sensing element for sensing temperature of airflow. A heater is provided on the probe to bias the temperature sensed by the thermometer or temperature sensing element, in a manner such that the temperature measured is at a substantially known offset from the static temperature surrounding the temperature sensor. Control of the offset can be achieved by regulating airflow or heat provided. The heating effect is controlled to be a substantially equal and opposite match to the decreased total temperature resulting from lower airspeed or decreased airflow. In this manner, the thermometer or temperature sensing element will essentially operate at a fixed offset above static temperature, that is the temperature in undisturbed air in which the aircraft is operating, over a fairly wide range of flow rates.

  • Patent number: 6827485
    Abstract: A turbine engine temperature sensing assembly includes a temperature sensor probe mounted relative to a surface of a turbine engine and subjected to air flow. The air moves past the temperature sensor probe in a first direction. A deflector post is mounted adjacent to the temperature sensor probe, and is spaced upstream of the temperature sensor probe to change air flow patterns around the temperature sensor probe and to intercept particles moving with the air flow toward the temperature sensor probe. The temperature sensor probe and deflector post are shown supported in a flow duct formed by a temperature sensor probe housing.

  • Patent number: 6712507
    Abstract: A temperature sensor device for use in a clean room has a housing, a covering tube extending from the housing, a lead wire protecting tube extending from the housing within the covering tube, and a generally cylindrical temperature sensor also disposed within the covering tube. A fixing end of the temperature sensor is detachably coupled to a distal end of the lead wire protecting tube. A plurality of lead wires protrude from the fixing end and extend through the lead wire protecting tube and into the housing. The temperature sensor includes a temperature sensor element at a free end thereof. The covering tube has at least one hole by which the temperature sensor element is exposed to the atmosphere. Accordingly, the temperature sensor is highly responsive to changes in temperature, and can be repaired, maintained or replaced with ease.

  • Publication number: 20040037348
    Abstract: A total air temperature (TAT) probe for measuring TAT includes an inlet scoop which receives airflow from free stream airflow moving toward the inlet scoop from a first direction. A first portion of the airflow entering the inlet scoop exits the probe through a main exit channel. A second portion of the airflow enters a TAT sensor flow passage, which extends longitudinally along an axis. This axis is oriented to form an angle of less than 90 degrees with the first direction from which the free stream airflow moves toward the inlet scoop. A sensor assembly extends longitudinally in the sensor flow passage and measures a total air temperature of airflow through the sensor flow passage. By increasing the angle through which the internal air turns, better inertial extraction of ice and water particles is realized. As a result, sensor clogging from accreted ice is significantly reduced. A second improvement is achieved by repositioning the sensor element to be more in-line with the internal airflow direction.

  • Patent number: 6641301
    Abstract: A method and apparatus for maintaining a viewing window of a detector substantially clean includes enclosing the detector within a housing, and moving a target surface relative to the viewing window to create an airflow adjacent the viewing window. The housing can include an aperture through which the viewing window of the sensor views the target surface. Motion of the target surface creates an airflow velocity adjacent the viewing window for maintaining the viewing window substantially clean. To increase the accuracy of the detector, a high emissivity area is provided on an outside surface of the housing which faces the target surface.
