The high frequency pressure transmitter is stable and reliable, and has excellent cost performance. AP90 high frequency dynamic pressure transmitter is rugged and durable to meet the requirements of more stringent industrial standards. AP90 high frequency dynamic pressure sensor is widely used in industrial support, industry support and equipment support. The series includes a variety of options, which are applied to different industries and different working conditions. AP90 high frequency pressure transmitter solves the needs for economic pressure monitoring in different occasions and serves a wide range of industries.

AP90 high frequency pressure transmitter is designed and manufactured by the company using special technology. This high frequency pressure transmitter is designed and manufactured by advanced MEMS technology. Three-dimensional integrated double-sided silicon piezoresistive pressure sensitive components through the ion implantation; fine lithography technology of the Wheatstone bridge, through silicon-silicon bonding technology; inverted V-slot design to make products with high sensitivity and dynamic characteristics. This principle design ensures the dynamic characteristics of the natural frequency of 500KHz and the measurement stability of the product, followed by the special high-frequency digital calibration circuit, which can convert the change of the pressure amount into a linear corresponding standard electrical signal, such as 4-20mA, 0-5V, etc., while ensuring the accuracy of the measurement.
