| 20090038376 | GAS ANALYZER WITH A TRACE MOISTURE SENSOR - An apparatus for measuring moisture in a gas flowing in one direction through an enclosed chamber includes a moisture sensor placed in the chamber. The moisture sensor includes a first and second electrode supported by a non-conductive member. Each of the first and second electrode has at least one elongated finger and a coating made of a moisture absorbing material. At least one elongated finger of the first electrode is substantially parallel with at least one finger of the second electrode. The apparatus further includes a gas temperature sensor, a moisture sensor temperature sensor, and a cooling element for controlling the temperature of the moisture sensor based on the data from the gas temperature data and moisture sensor temperature data. Further, the apparatus includes a source of electrical current providing a voltage across the first and second electrode. | 02-12-2009 |

| 20100319435 | SYSTEM AND METHOD FOR DETECTING MOISTURE - A technique facilitates the detection of moisture. The technique utilizes distributed sensor lines deployed along an insulated vessel, such as an insulated pipe. The sensor lines are used to measure temperature and to determine a differential temperature across the insulation between the sensor lines. Changes in the differential temperature can be detected, and those changes are used to determine whether moisture has intruded into a specific region of the insulation. | 12-23-2010 |
| 20110000281 | Method and System for Monitoring Steam Quality - A method and apparatus for monitoring the quality of steam used in a process is disclosed. A pressure and temperature sensor is exposed to the steam on either side of an inline pressure drop device such as an orifice or pressure reducing valve. The measurements are transmitted to a controller that calculates the steam quality percentage or superheat value. An alarm is issued if the steam quality is beyond a predetermined tolerance. | 01-06-2011 |
| 20130036794 | DETECTION SYSTEM AND HUMIDITY DETECTION METHOD FOR DETECTING VOLATILE ORGANIC COMPOUND - Detection system and humidity detection method for detecting volatile organic compound comprises a device for introducing clean air and a controller, wherein the device for introducing clean air is connected with a test chamber; a test chamber sheath is sleeved outside the test chamber; the test chamber is provided with a temperature sensor for detecting the temperature in the test chamber, a high-temperature test exhaust device is connected with a high-temperature exhaust pipeline of the test chamber, and a low-temperature test exhaust device is connected with a low-temperature exhaust pipeline of the test chamber; a pipeline connecting the test chamber with the low-temperature test exhaust device is also provided with a dew point sensor for detecting dew point of the air in the low-temperature exhaust pipeline; and the temperature sensor and the dew point sensor are connected with the controller. | 02-14-2013 |
| 20140053628 | Mountable Sensor for an Aircraft - A sensor system runs real-time software on the processor to receive and log temperature and humidity data from the sensors. A processor processes the data, reformats the data packaged with GPS information provided by the centralized sensor control system for transmission to the platform receiver (including error checking), and provides a diagnostic interface for displaying logged data and status information. This data is time stamped and transmitted to the centralized sensor control system across the external control/data interface. | 02-27-2014 |
| 20140083166 | Thermoelectric moisture detector - The apparatus has a chemical energy reservoir that releases thermal energy upon contact with moisture. The apparatus furthermore has a converter that is embodied to convert the thermal energy into electrical energy; and a circuit that is embodied to generate, operated by the electrical energy, an electrical signal for reporting the event. | 03-27-2014 |
| 20150293002 | METHOD OF MEASURING CONCENTRATIONS OF GAS MIXTURES - A method of measuring concentrations of gas mixtures is disclosed in which an ionic liquid and/or low vapor-pressure organic solvent is exposed to a gas mixture being tested to form a solution of the gas components in the liquid. The vapor pressure of the solution is then measured at one or more other temperatures and compared to predicted vapor pressures based on known individual vapor pressure profiles of the gas components in the liquid in order to determine the actual proportions of the components in the gas sample. | 10-15-2015 |
