Abstract

PURPOSE:To enhance the response of an air conditioning meter that can be controlled at a remote place, by forming all control loops actuating a switch device in an optical way. CONSTITUTION:The air pressure applied to the switch device 2 is detected by a photosensor 14 which receives the light from the light source 15 via the optical fiber 17. The output of this detection is measured by the pressure measuring device 20 and then supplied to the controller 21. The controller 21 controls the control light source 22, and this output light is applied to the actuator mechanism 12 via the optical fiber 24. Thus the mechanism 12 works to supply the compressed air within the air chamber 9 and supplied from the air supply source 7 to the device 2. In such way, the control loop of the device 2 is formed in an optical way to enhance the response of an air conditioning meter.
