Product Overview
The pressure transmitters produced by our company adopt advanced piezoresistive sensing technology. The self-developed highly integrated, multifunctional digital, and intelligent transmitter adopts mature and reliable sensor technology, and is carefully designed by combining microcontroller technology and sensor digital conversion technology. The core controller adopts a sixteen bit microcontroller, whose * function and high-speed computing capability ensure the excellent quality of the transmitter. Small size design, long-term stability, economic reliability, and wide application.
working principle
A pressure sensor is a Wheatstone bridge diffused on a single crystal silicon wafer, and the measured medium (gas or liquid) applies pressure to change the resistance value of the bridge wall (piezoresistive effect), generating a differential voltage signal. This signal is amplified by a dedicated amplifier to convert the signal corresponding to the range into a standard analog signal or digital signal.
