Product details

This series of pressure transmitters adopts internationally advanced high-precision and high stability sensors, equipped with ASIS high-performance amplification circuits. After thousands of fatigue impacts, high and low temperature cycle aging, and precise digital temperature compensation processes, they are refined through stainless steel full sealing welding (laser welding); High quality sensors, strict calibration processes, and sophisticated assembly techniques ensure the excellent quality of this product. It is particularly suitable for measuring the pressure of hydraulic, pneumatic and other media, and even for harsh environments such as sewage, steam, mild corrosiveness, and gas measurement. Building a foundation to meet various customer needs; Adopting stainless steel integral components, imported crystal element encapsulated diffusion silicon core and advanced surface mount technology, it has high sensitivity, stable performance, and good impact resistance. 316 stainless steel fully sealed welding, compact and compact structure, with good moisture resistance and excellent medium compatibility; Measurement medium: weakly corrosive liquid; A weakly corrosive gas.
