Title:
SENSOR UNIT AND GAS DETECTOR
Document Type and Number:
Japanese Patent JP2009222647
Kind Code:
A
Abstract:

To provide a sensor unit and gas detector for accurately performing flow detection by a flow sensor and accurately detecting the concentration.

A gas sensor 5 is constituted by a sensor element 8. The flow sensor 6 is constituted by a Pt heater 14, an upstream temperature sensitive resistance element 14, and a downstream temperature sensitive resistance element 15. Both the gas sensor 5 and the flow sensor 6 are mounted on one support base 3. The flow sensor 6 and the gas sensor 5 are disposed so that the flow sensor 6 is arranged on the upstream side of the flow direction Y1 of atmosphere more than the gas sensor 5.
