Abstract:
A gas concentration measuring device ( 1 ) including a light emitter ( 3 ) and a light receiver ( 4 ) which are disposed so as to be opposed to each other with a hollow tube-like measurement pipe ( 2 ) interposed therebetween. The device ( 1 ) is configured to measure concentration of target gas passing through the measurement pipe ( 2 ) using light applied from the light emitter ( 3 ) transmitted through the inside of the measurement pipe ( 2 ), and received by the light receiver ( 4 ). Purge gas guide pipes ( 11, 13 ) through which purge gas is introduced into optical systems of the light emitter ( 3 ) and the light receiver ( 4 ) are connected to a side wall of the measurement pipe ( 2 ). The measurement pipe ( 2 ) includes a gas entrance portion ( 21 ) having a tapered shape widening from a gas supply port toward a downstream side thereof.

Claim (Index 1):
A gas concentration measuring device including a light emitter and a light receiver which are disposed so as to be opposed to each other with a hollow tube-like measurement pipe interposed therebetween, the device being configured to measure concentration of target gas passing through the measurement pipe using light applied from the light emitter, transmitted through an inside of the measurement pipe, and received by the light receiver, wherein:\n purge gas guide pipes through which purge gas is introduced into optical systems of the light emitter and the light receiver are connected to a side wall of the measurement pipe, and are provided so as to be opposed to each other and to be orthogonal to a flow direction of the target gas; and the measurement pipe includes a gas entrance portion having a tapered shape widening from a gas supply port toward a downstream side in the flow direction of the target gas.
