ABSTRACT:
An optical fiber joint type ion-concentration measurement apparatus in which electrical signals which are detected by an ion selective electrode are transformed into optical signals which are transmitted to a receiving side of the apparatus by means of optical fibers. The detected signals from the electrode are frequency modulated by a voltage/frequency converter and the output of the voltage/frequency converter is used to control an electronic switch. The electronic switch controls a series circuit including a power source and a charging-discharging capacitor and a light emitting diode. The frequency modulated transformed detected signals therefore cause the light emitting diode to emit optical signals which are then transmitted by means of optical fibers. On the receiving end of the apparatus, the optical signals are transformed into electrical signals by a photo diode and then demodulated by a frequency/voltage converter to reproduce the original detected signals from the ion selective electrode.
