  • Publication number: 20130312485
    Abstract: A thin plate member which has a groove portion recessed toward the inside in a radial direction with a gap interposed between the thin plate member and the outer surface of a site on the front end side of a main body section. At least one end of the thin plate member is joined to the outer surface of the main body section and is provided radially outside the site on the front end side of the main body section. A seal member is disposed in the groove portion and has elasticity due to resin. Since the gap functions as a heat-insulating layer and is interposed between the seal member and the main body section, heat conduction from the main body section, that is, heat conduction through a first pathway is reduced, and thus deterioration of the seal member due to heat is suppressed.

The device comprises a probe that has a closed tubular container intended to contain a pressurized medium, and that has a wall thickness t that corresponds to the predetermined critical corrosion. A protective coating is arranged essentially over the entire outside of the container with the exception of a surface that is intended to be subjected to corrosion attack. The container is allowed to corrode so that the container becomes perforated, whereupon the pressure of the pressurized medium falls. The pressure change is measured by means of a pressure gauge, and in this way, information is obtained about the fact that the corrosion has reached the predetermined critical level.

  • Publication number: 20130145818
    Abstract: A sensor unit for attachment to a container such as a bag or other vessel used to retain material includes a clamping mechanism for attaching the sensor unit to the container. The clamping mechanism may be configured to break or provide an indication that the connection between the sensor and container has broken that is visually detectable before a leak of material occurs or is detectable by a person visually monitoring the container or sensor. Such an indication can also indicate that the sensor was previously used and should not be used again for single use applications. Such a visual indicator is separate and different from seeing an actual leak and permits an event that may desterilize material within the container or lead to other problems to be corrected prior to use of a single use reaction system.

  • Patent number: 8459097
    Abstract: A gas concentration of a gas may be detected from a gas mixture using gas detectors sensitive to the gas. A gas concentration may be measured by a first gas detector at a first operating temperature, and a first signal characteristic of the measured gas concentration may be provided. An operating temperature of the first gas detector may be changed to a second operating temperature, or a second gas detector having the second operating temperature may be provided. A gas concentration may then be measured at the second operating temperature, and a second signal characteristic of the measured gas concentration may be provided. The gas concentration of the gas from the gas mixture may be determined using a first concentration value allocated to the first signal and a second concentration value allocated to the second signal.

  • Publication number: 20130113924
    Abstract: A plant observation device measures the growing state of a plant placed in a measurement area and the growth environment in the measurement area while moving within the measurement area where the plant is cultivated. The quantity of light is measured during growth environment measurement, and a light transmitting state of the measurement area is detected based on the measured quantity of light and the time of light quantity measurement. The measured growing state information and growth environment information are transmitted, together with positional information, to a server of a remote monitoring system. The growth environment in the measurement area is then optimally controlled based on the growing state information and the growth environment information.
