[Solution] In the present invention, a measurement target is irradiated, in a time sharing manner, with light of a first wavelength and light of a second wavelength that have different optical absorption rates with respect to the measurement target. The light of each wavelength, arriving optically via the measurement target as a result of irradiation with the light of each wavelength, is received at a shared light-receiving sensor. A differential signal is formed, the differential signal being of a signal pertaining to the light of the first wavelength and a signal pertaining to the light of the second wavelength, the signals outputted from the light-receiving sensor upon receipt of the light. The concentration of a chemical component in the measurement target is derived on the basis of the differential signal.

In a step motor driven cam valve 1 a stem 7 is disposed to freely ascend and descend within a body 2 having an in-low passage 2a, an out-flow passage 2b, a valve chamber 2c, and a valve seat 2d. The stem 7 is descended by an actuator disposed at a position above the stem 7 and composed of a step motor 9 and a cam mechanism 10 that changes a rotational motion of the step motor 9 to a linear motion and transmits the linear motion to the stem 7. A diaphragm 3 disposed within a valve chamber 2c or a valve body 30 arranged at a lower end part of the stem 7 rests on the valve seat 2d. A lift support mechanism 11 that supports the actuator to freely ascend and descend is arranged at a bonnet 5 that covers the valve chamber 2c of the body 2. A height fine-adjustment mechanism 12 finely adjusts the height of the actuator relative to the stem 7 and is arranged at the lift supporting mechanism 11.

摘要： It has been found to be disadvantageous that, with a conventional pressure type flow control apparatus, it is not possible to determine the state of a valve on the downstream side of a throttle mechanism with a flow rate output signal due to the structural reason of the apparatus. To overcome the difficulty, the determination of whether a valve on the downstream side of a throttle mechanism is open is achieved at ease using the state of changes of a flow rate output signal while a pressure type flow control apparatus is in operation.
With a pressure type flow control apparatus, a valve on the downstream side of a throttle mechanism is released and a flow rate setting value Qe to be inputted to a pressure type flow control apparatus is changed to detect the magnitude ΔV of changes of a flow rate output signal Qo from a pressure type flow control apparatus while said flow rate setting value Qe changes so that it is determined either that a valve on the downstream side of a throttle mechanism is opening normally in the case that the magnitude ΔV of changes of said flow rate output signal Qo is found to be above the predetermined value, or that the releasing operations are malfunctioning in the case that the magnitude ΔV of changes is found to be below the predetermined value.
