UPB1151 capacitive pressure transmitter 4~20ma
Descriptions:
Based on metal capacitive technology, UPB1151 series differential pressure transmitters is designed by using selected high accuracy & stability electric capacitive sensor, that use one-side or two-side stainless steel or tantalum isolated diaphragm.
After strict temperature compensation, linearity compensation, signal ampl ified, V/I transforming, antipolarity protection, pressure overload, and current l imiting processing, the parameters l ike differential pressure, gauge pressure, fluid, and level can be transformed to standard signal of 4~20mA or 0~20mA by UIB1151.
UPB1151 series metal electric capacitive pressure transmitters can be connected with Process Automation Instrumentation or computer control system, real izing precise measurement for corrosive gas pressure, liquid pressure, steam pressure, level or fluids etc.
UPB1151 series metal capacitive pressure transmitter is widely used in technical areas such as petroleum industry, chemical industry, steel and iron industry, electric power, food, papermaking industry, spinning and weaving, medicine and environmental protection and so on
