BP100 single crystal silicon threaded flat film pressure sensor

The OEM product of BP100 single crystal silicon threaded flat film pressure sensor adopts a one-time silicon oil filling technology. The diaphragm directly contacts the measuring medium, and the felt pressure is transmitted to the pressure chip through silicon oil to generate an electrical signal. The compensation circuit corrects the pressure signal to a linear pressure signal. The exposed pressure diaphragm on the threaded end face can directly feel pressure, which can prevent scaling, hygiene, and viscous pressure blockage. It is particularly suitable for measuring the pressure and liquid level of viscous fluids with hygiene requirements in the medical and food industries, and is widely used in hygiene industries such as food, medicine, and brewing. The company can customize products for users, undertake products with special structures and sizes, and have a mature batch production line that can complete production tasks in a timely and high-quality manner.
