Claims (1)
に、他方の接続口１３は基準比較用マスターＭに、夫々
配管接続すると共に、毎回のエアーリークテストの封入
工程Ｔ、の開始時において・上記両接続口１２．１３の
内のいずれか一方の圧力を大気に開放するソレノイド弁
Ｓ■３を、該一方の接続口に連通連結された配管途中に
付設し、上記差圧検出器７とこれに接続される増幅器１
４゜１６等の作動が正常か否かを、エアーリークテスト
の一サイクル毎に自己診断するように構成されたことを
特徴とするエアーリークテスト装置。One connection port 12 of the differential pressure detector 7 is connected to the workpiece W to be tested.
Then, the other connection port 13 is connected to the standard comparison master M, and at the start of the sealing process T of each air leak test, one of the connection ports 12 and 13 is connected to the reference comparison master M. A solenoid valve S3 for releasing the pressure to the atmosphere is attached in the middle of the pipe connected to the one connection port, and the differential pressure detector 7 and the amplifier 1 connected thereto are connected.
An air leak test device characterized in that it is configured to self-diagnose whether or not the operation of the air leak test device is normal or not at each cycle of the air leak test.
