Gas leakage detector for gas controller, has detection chamber, and pressure detector that is arranged in detection chamber for detecting gas-pressure signals received from pressure sensor, for controlling magnetically excitable device

摘要

The detector has a detection chamber and a valve chamber that are formed inside a base body (10). A reed switch and a magnetically excitable device are arranged in the valve chamber for closing and opening of channels and for controlling the switch, respectively. A pressure detector (70) is arranged in the detection chamber for detecting gas-pressure signals received from a pressure sensor, and for controlling the excitable device.
