<p>PURPOSE:To make it possible to detect the gas pressure variations of a plurality of gas compartments precisely by a least number of gas pressure detectors, even at the time of a rapid rise of the gas pressure, and to prevent influence on other gas compartments caused by decomposed gas etc. CONSTITUTION:A filter 25 is fitted between gas-pressure-detector side gas piping and gas compartment side gas piping. This filter 25 has a filter body 1 contained in a filter containing part 2 in a freely progressable way, and the filter body 1 is being pressed on the side of the gas compartment by a spring 5 inserted in the filter containing part 2. Besides, an end of an operating rod 6 which penetrates the end surfaces of the filter containing part 2 is fixed to the filter body 1.</p> |
