FST800-3051AP Intelligent Absolute Pressure Transmitter
Product Introduction
The FST Capacitance Differential Pressure transmitter is based on the new advanced digital production technology. Digital circuit is adopted instead of analog signals to amplifier circuit and A/D conversion circuit, which improves the measurement accuracy. standardized mounting structure design, easy to install. The sensitive diaphragm has a one-way overload protection function,the maximum withstand pressure is 320 bar,and is featured with high reliability and good longterm stability.FST Capacitive Intelligent Differential Pressure Transmitter build-in a high-performance digital circuit which carefully desighed the working condition of RFI & EMI resistance and the surge voltage. It has the characteristics of strong RFI & EMI resistance, wide power supply range and polarity protection, meeting IEC, CE(EMC) requirement.Intelligent digital temperature compensation circuit store the corresponding temperature calibration value in the chip. when the sensor affected by temperature, it compensates automatically, which solve the problem of temperature drift, and improve accuracy and environmental suitability. It is widely used in electric power, water conservancy, metallurgy, petrochemical, pharmaceutical, environmental protection and other industries.
