一、概述 电容式差压变送器,简称差容表,是电动单元组合仪表变送单元品种之一。它采用了微位移式工作原理的差动电容式测量元件,变送过程无机械传动和机械调整,唯一可动件是移动甚微的测量膜片。因此结构简单、体积小,且具有良好的稳定性、可靠性和抗震性。 差容表,国内仅有少数厂家可以小批
First, an overview Capacitance differential pressure transmitter, referred to as capacitance table, is one of the varieties of electric unit combination instrument transmission unit. It uses a differential displacement displacement measuring principle of differential displacement components, the transmission process without mechanical transmission and mechanical adjustment, the only movable member is a very small mobile diaphragm measurement. Therefore, the structure is simple, small size, and has good stability, reliability and shock resistance. Tolerance table, only a small number of domestic manufacturers can be small batches
