摘要： A multi-function sensor is disclosed which provides a reliable and simple device for accurately measuring and/or monitoring the ambient conditions within a container or the like, such as the level of a fluid, the turbidity of a fluid, the temperature of a fluid or surrounding environment and the ambient pressure. The sensor incorporates a fluid level sensor module, a turbidity sensor module, a temperature sensor module and a pressure sensor module. The fluid level sensor module utilizes a plurality of thermocouple junctions grouped in pairs with the pairs being spaced along a line extending generally in the direction in which the liquid level may vary. The thermocouple junctions are connected in series and produce a signal indicative of the level of liquid along the sensor. A turbidity sensor module is also integrally included on the multi-function sensor. Additionally, temperature and pressure sensor modules may also be incorporated in the multi-function sensor. Alternatively, a fluid flow rate sensor module may be included in place of the liquid level sensor module.

摘要： A sensor system for detecting the presence of a target analyte. The system comprises a first conductor, a second conductor, and a sensor film. The sensor film is positioned between the first conductor and the second conductor. The sensor film includes a crosslinked siloxane polymer comprising a monomer having a hydrocarbon side group. The sensor film has an absorptive affinity for the target analyte. The electrical capacitance of the sensor system changes upon absorption of the target analyte by the sensor film.

摘要： A fuel fired appliance exhaust gas parameter sensor for continually detecting gas parameter emissions, such as CO, NOx and O2, may be located above the appliance near the appliance exhaust outlet. The sensor may be located near or under a draft hood located near the exhaust outlet. The sensor remains relatively cool by draft air moving from outside the draft hood and into a chimney, the draft being hastened by the heated, rising chimney gases. A sensor bracket may be attached to the appliance and the sensor to appropriately position the sensor under the draft hood. Alternatively, the sensor may be located on a tube that continually samples combustion exhaust. The tube may be located outside of the draft hood perimeter to maintain a low sensor temperature, while multiple tube coils around the exhaust outlet may be used to further cool the sampled gas.
