  • Patent number: 7994416
    Abstract: A set of electrical connector pins for a thermocouple includes two materially similar conductor pairs, each conductor pair having conductors composed of a different material, and carried by an electrically insulating connector housing. The different materials of the conductor pairs provide a partial compensation to the thermocouple EMF developed between the hot junction and the cold junction when engaged thereto for the different type thermocouples. The conductors of each pair are operable to engage with two thermoelement conductors that form a thermocouple of differing types. The thermocouples provide a hot junction electrical interconnection therebetween at one end and are coupled to a cold junction at another end.

  • Patent number: 6126311
    Abstract: A dew point sensor includes a micro-cantilever beam formed on a substrate. A cooling device and a temperature sensor are in thermal contact with the micro-cantilever beam and a control circuit is coupled to the micro-cantilever beam, the cooling device and the temperature sensor. The control circuit controls and monitors a resonance of the micro-cantilever beam, controls a temperature of the cooling device and receives a temperature indication from the temperature sensor. Using the above information, the dew point temperature is determined by identifying the temperature of the micro-cantilever beam when its resonance changes due to a change in mass caused by the formation of dew on the micro-cantilever beam when the dew point is reached. A method of determining the dew point is also disclosed. The method includes exciting a micro-cantilever beam in a vibratory mode and decreasing a temperature of the micro-cantilever beam.
