Products Description
Product Definition
The Nexisense FST800-10 IIC output pressure sensor is a high-precision digital pressure sensor that features a 14-bit digital output and supports I²C and SPI communication protocols. The sensor transmits external pressure to the sensitive element through a 316L stainless steel diaphragm and measures all pressure media compatible with 316L stainless steel using silicone oil filling.
Nexisense Working Principle
The Nexisense FST800-10 IIC sensor operates based on the piezoelectric effect. External pressure acts on the 316L stainless steel diaphragm, altering its shape and affecting the internal sensitive element. This change is converted into an electrical signal, calibrated and compensated by an integrated circuit, and ultimately output as a digital signal. This process ensures high precision and stability, making it suitable for various industrial applications.
