PAS07xx is a pipeline microfluidic pressure sensor, which can be controlled by CAN/RS485 network, or output pressure value through an analog interface. This series of sensors adopts a special liquid circuit design, has the smallest liquid retention, and has a high pressure sensitivity. A special filter is integrated inside, which can filter and compensate for pressure deviation, temperature drift, and nonlinearity. , Suitable for pipeline pressure monitoring of various analytical instruments and laboratory equipment.，Solve the problems of air suction, needle blockage, clot, overpressure burst pipe, etc. in the liquid path, and can also be used to distinguish different density media in the pipeline
