Abstract
【解決手段】濃度センサ30がフィルタ要素10に取付けられ、濃度センサ30の付近に、あるいは濃度センサと一体化して無線トランスミッタ40も位置付けられる。無線トランスミッタ40は濃度センサ30と共に一つの一体部品内にカプセル封入され得、あるいはトランスミッタ40及びセンサ30は分離され、電気信号の如きを介して相互通信され得る。フィルタハウジング20の外側に位置付けた無線レシーバ60が無線トランスミッタとの通信用に使用され無線レシーバとしてはRFIDリーダーあるいはベースステーションが用いられる。RFIDタグのような無線トランスミッタ40を濃度センサ30にカップリングさせ得る。

Description
この概念をもっと分かり易く説明すると、製造会社において、製造設備に入る各部品にRFIDタグが貼り付けられ、RFIDタグを貼り付けた部品が製造工程に送られ、製造工程下に別の部品と組み合わせたサブアセンブリとされ、最終的に製品として仕上げられる。RFIDタグを使用すると製造会社側で製造プロセス全体を通した特定の部品の動きを追跡できるようになる他、任意の特定アセンブリあるいは仕上げ製品を含む特定部品を識別することもできるようになる。
本装置は多くの用途に対して有益に使用され得る。例えば、新規開発の完全性試験はキャリヤーにトレーサガスを追加するコンセプトに基づくものであり、このトレーサガスが検知されればその感度は標準的な拡散試験におけるそれよりもずっと高くなることから、トレーサガスを検出し、その結果をフィルターハウジング外に伝送できれば非常に有益である。別の用途では、フィルターハウジング内のタンパク質濃度を監視できれば、膜面位置でのタンパク質濃度が高い信頼性及び再現性を得るべく維持されるように運転条件を調節できるようになる。
これにより、トランスミッタ40のデータ送信速度を濃度サンプリング速度と異ならせることが可能となる。例えば、濃度を毎秒10回サンプリングさせ、その間に送信されるデータを一回だけとすることができる。
ある実施例では、トランスミッタとの通信用の無線レシーバ60がハウジング20の外部に位置付けて使用される。好ましい実施例では、RFIDリーダーあるいはベースステーションが用いられるが、RFIDリーダーは、定期間隔でトランスミッタに処理要求を出す(query)ような構成のものとされ得、あるいは装置オペレータの要求に応じて読み取りを実施するように手動操作され得る。別の実施例では無線レシーバ60にも記憶素子を持たせることができるが、この場合はハウジング内の装置に必要な複雑度が緩和される。本実施例では無線レシーバは、好ましくは定期間隔で無線トランスミッタ/濃度センサに処理要求を出し、無線トランスミッタからその時点で決定されたものとしての最新の濃度センサ測定値を受け、次いでその値を記憶素子に記憶する。記憶素子のキャパシティは変動可能であって色々の因子に基づいて決定され得るが、それらの因子には、これに限定しないが、測定値の受信速度、記憶データのプロセス処理速度、記憶素子の外部環境との通信頻度、が含まれる。
本発明の、定義された物理的構造は多用途において有益なものであり、そうした用途の幾つかを以下に説明するが、そうした用途の全てを列挙することを意図したものではない。
運転に際し、センサ30が濃度を測定し、測定濃度値がトランスミッタ40によりフィルターハウジングの外部に伝送され、伝送されるこの濃度値を外部のレシーバ60が受信する。比例積分微分(PID)制御あるいは比例積分(PD)制御の様なアルゴリズムを用いる従来の制御ループを使用して、現在濃度と、受信した濃度測定値とに基づいて所望の最新経膜圧が算出され得、この新規値がシステムに適用される。
一実施例ではプラスチック製のフィルターハウジングが使用され、任意時間での、ハウジングを通過しての無線トランスミッタによる濃度データ伝送が可能となる。
20 ハウジング
30 濃度センサ
40 トランスミッタ
50 記憶素子
60 無線レシーバ
