BST6800-DP pressure transmitter principle capacitive pressure sensor, also known as capacitance diaphragm, it works by converting the displacement of the elastic element as a change in capacitance. To load the diaphragm as a movable plate capacitor, which fixed plate composed of a variable capacitor. When the measured pressure changes, pressure diaphragm displacement and changing the distance between the plates, measuring the corresponding capacitance change, we can see the value of the measured pressure differential pressure transmitter retail Yunnan boilers, pressure sensitive element Pictured two-room structure schematic concave spherical metallic glass insulating layer measured as a fixed electrode, intermediate clamped elastic flat diaphragm as a movable electrode Yunnan boiler differential pressure transmitter, which form two capacitors. Entire diaphragm with diaphragm seal, full of silicone oil in its interior. Both measured by the diaphragm feel the effects of stress, pressure transmission by silicone elastic diaphragm displacement, when the pressure difference is positive pressure, the movable plate will be near the low side; on the contrary, the movable plate on the high pressure side close. Changes in the distance between the capacitor plates, cause changes on both sides of the capacitor capacitance value. By measuring the capacitance change value Yunnan boiler differential pressure transmitter installation, calculate the size of the measured pressure. On the out of water Dahua Group ammonia project, put Sisson BST6800 series pressure transmitter 56 sets, BST6800 series differential pressure transmitter 43 sets, BST6800-RG Series Intelligent remote pressure transmitter to 62, BST6800- YB series of intelligent input type level transmitter 36. Products operating normally, stable quality, on-site production uptime has made a great contribution.
