  • Patent number: 8863820
    Abstract: A temperature measurement device in combination with a furnace heat exchanger is disclosed and claimed. An instrumented heat tracer sensor is launched into the heat exchanger which records the temperature of the fluid and performance at data points along the length of the heat exchanger. If a spike in the temperature as measured and recorded, since the speed of the heat tracer sensor is known, the location of the temperature increase is known which infers a burn through in the furnace. A three way valve includes a retrieve port, a chamber port, and a launch port. A small sensor control pump and a large heat exchanger flow pump propel the heat tracer sensor through the system. A plastic chamber retains the heat tracer sensor for interrogation and downloading information when the sensor is not in use in the heat exchanger. A control station communicates with the heat tracer sensor and extracts the stored temperature data therefrom.

    Abstract: Scale deposition on a heat transfer surface in a liquid system such as a heat exchanger is estimated by directing of small portion of the liquid flow through a test cell, consisting of a sensor positioned on and projecting through a conduit wall. The sensor consists of a conductive block containing a heater and having a heated wetted test surface that is flush with the inside of the conduit wall and in contact with the flow through the conduit. Within the conductive block are two temperature sensors which are at different distances from the heated wetted test surface and the heater. The periphery of the apparatus is designed to reduce heat flow through the periphery and allow greater heat flow through the heated wetted test surface. By comparing the temperature differential between the two temperature sensors to the differential when no scale is present, the presence of and amount of scale can be determined, based on reduced heat transfer through the heated wetted surface caused by the accumulated scale.

  • Patent number: 6485175
    Abstract: A thermowell assembly (20) shown in FIG. 2 is positioned in a pipeline (10) for sensing the temperature of the fluid medium in the pipeline (10) for transmitting the sensed temperature to a meter (12). A temperature sensing probe is received within a temperature conducting tube (36) forming a thermowell and having a plurality of annular fins (40) extending thereabout. In the embodiments of FIGS. 1-7, a liquid (50) is provided in an annular space between the thermocouple (28) and the temperature conducting tube (36). Non-metallic members (70, 74, 80) are positioned between the pipeline (10) and the temperature transmitting tube (36) to isolate thermocouple (28) from ambient changes in the temperature of metal pipeline (10) which may result in an error in the temperature of the flow medium sensed by the thermowell assembly (20). High temperature embodiments shown in FIGS.

  • Patent number: 6431459
    Abstract: A heater, especially a liquid fuel-operated water heater (10) or air heater of a motor vehicle in the form of an auxiliary heater or a parking heater has a housing jacket (1) and a heat exchanger (2) as well as with a control device (11) for regulating or monitoring the heating operation via at least one temperature sensor (3), especially a regulating temperature sensor and/or overheating sensor. The temperature sensor (3) is arranged on the underside of a control device bottom plate (4) facing the temperature sensor (3) on the housing jacket (1), wherein the temperature sensor (3) extends through an opening of the housing jacket (1), especially a water jacket, in the direction of the heat exchanger (2) and is preferably pretensioned by a spring. As a result, the temperature sensor can be mounted on the control device bottom plate already during the manufacture of the control device and finally mounted together with the control device bottom plate rapidly and reliably.

  • Patent number: 6290388
    Abstract: An integrated environment temperature sensor device provides improved temperature sensitivity by using a diode as the sensing element. The integrated sensor device comprises a heater element for creating a fixed quantity of heat energy. The sensor device also comprises an integrated circuit diode which receives the fixed quantity of heat energy from the heater element. The integrated circuit diode has a constant forward bias current applied thereto and a change in environment temperature is reflected in a voltage change across the integrated circuit diode. The integrated circuit diode further comprises an electrically insulating layer positioned substantially between the heater element and the integrated circuit diode for electrically insulating the two from each other.

  • Patent number: 5527111
    Abstract: The invention provides a contact temperature sensor consisting of a planar contact plate, a thermocouple element attached to the contact plate for determining the temperature of the contact plate, and a deflectable and tiltable holding system. The connection lines to the thermocouple element are wound around a tube. By vulcanisation with a rubber-elastic material, a one-piece elastic formed body is produced which connects together the contact plate, holding piece and inner tube. Through the rubber-elastic spring action and the deflectability and tiltability of the contact plate with reference to the surface of the object of measurement, and improved flow of heat to the contact plate and improved measurement results are achieved.

  • Patent number: 5312187
    Abstract: The invention herein relates to a kind of safety pin with an attached multi-function thermometer which consists mainly of a temperature display and pulse tone emitting integrated circuit board. The enclosure of the aforesaid integrated circuit board can be fabricated in the shape of various animals or cartoon characters. A safety pin is mounted on the rear side of the enclosure for fastening the device onto the clothing of an infant. Extending from the integrated circuit board is a coiled conductor connected to a threaded seat that is fastened in screw-on fashion to a heat sensor rod contained in a pacifier nipple. As an infant sucks the pacifier nipple, the oral temperature of the infant is measured by the heat sensor rod and the temperature reading is shown via a liquid crystal display on the integrated circuit board. The integrated circuit board also has specially designed temperature setting functions.

  • Patent number: 5141335
    Abstract: A thermocouple connector for measuring the temperature of a surface includes a heat conductive casing having a hollow interior and a linear ridge on one side. The apex of the linear ridge forms a contact zone with the surface. A pair of thermocouple leads extends into the hollow interior of the casing, and are attached to the casing at and parallel to the linear ridge. The contact zone is sufficiently wide in relation to the distance of the contact zone from the leads such that welds along the side of the contact zone penetrate the contact zone, but do not penetrate so far as to burn the leads.
