CECC-630型电容式差压变送器属微位移式变送器,它与目前国内常用的差压变送器相比,具有一系列优点。 1.精确度高,线性好。除膜片作微小位移外,无其它可动零、部件,而且电容相对变化量又较大,因此精确度可以做到0.5～0.2级。 2.稳定性、可靠性好。因为是位移式,结构简单,零、部件少,而且测量部件采用全焊接结构,又采用温度补偿和过压保护等措施,因此稳定性、可靠性均较
CECC-630 capacitive differential pressure transmitter is a micro-displacement transmitter, it is currently used in the domestic differential pressure transmitter compared with a series of advantages. 1. High accuracy, good linearity. In addition to the diaphragm for small displacement, no other moving parts, components, and relatively large changes in the capacitance, so accuracy can be 0.5 to 0.2. 2. Stability, good reliability. Because it is a displacement, simple structure, zero, fewer components, and the measurement of components using all-welded structure, and temperature compensation and over-voltage protection and other measures, so the stability and reliability are more
