Title:
プレートコーティングを施し、粒子フィルタを備えた内蔵型低コスト容量性圧力トランスミッタ
Document Type and Number:
Japanese Patent JP2005530150
Kind Code:
A
Abstract:
A capacitive pressure transmitter is provided. In one aspect, the transmitter includes a capacitive pressure sensor coupled directly to the measured media without any intervening fluid isolation. A filter is preferably used to keep particulates from reaching the measuring diaphragm. In another aspect, a capacitive pressure transmitter is provided with at least one self-contained isolator interposed between a process connection and the capacitive pressure sensor. In both aspects, the capacitive pressure transmitter is relatively small and preferably constructed from materials that facilitate low-cost manufacture.
