초록 ▼

The present invention provides an apparatus for sensing the temperature of surrounding air. The apparatus is thermally isolated from the external environment and more accurately provides an indication of the medium temperature while providing fast response. The apparatus includes a temperature sensing device whose resistance varies with temperature and a conditioning circuit for measuring the resistance and producing an electrical signal which is insensitive to external resistive loading and which has a magnitude responsive to the sensed resistance. The apparatus includes a non-metallic housing which encapsulates the temperature sensitive device and the conditioning circuit. The housing forms a cage portion which surrounds the temperature sensing device and is adapted to protect and to provide air flow to the temperature sensing device.

An apparatus for sensing the temperature of a gas, comprising: a thermistor having a resistance which varies with temperature; a conditioning circuit being electrically connected to said thermistor and adapted to measure a resistance across the thermistor and produce an electrical signal which is insensitive to external resistive loading and which has a magnitude responsive to the sensed resistance; a tubular portion connected to said conditioning circuit, said tubular portion including a rigid tube and a metallic tube, said thermistor being micro-encapsulated within said rigid tube, said rigid tube being encased by said metallic tube to prevent the gas from directly contacting said thermistor; and a non-metallic housing encapsulating said tubular portion and said conditioning circuit, said housing forming an interior cavity and a front cavity, wherein said conditioning circuit is sealed within said interior cavity and said tubular portion is within said front cavity and said housing having a cage portion surrounding said tubular portion, said cage portion being adapted to protect and to provide air flow to said tubular portion.
