Products Description

Board-mount pressure sensors suitable for pressure measurement applications with extremely low requirements on form factor and power consumption.

The SG-M35 onboard pressure sensor based on MEMS technology are the mainstream.Typically,four piezoresistors are etched on a semiconductor silicon wafer and connected to form a wheatstone bridge,followed by etching a pressure back cavity to create a sensitive silicon diaphragm.When pressure is applied to the back cavity,the sensitive silicon diaphragm deforms,causing changes in the resistance values of the four resistors,thereby generating a voltage output proportional to the applied pressure.

The SG-M35 onboard pressure sensor is a high-precision digital pressure measurement module designed for automotive systems, industrial control, aerospace auxiliary equipment, hydraulic units, and harsh-environment monitoring applications.

It offers standard digital output, wide pressure ranges, ±0.25% F.S. accuracy, and rugged environmental resistance, making it ideal for long-term installation in demanding onboard and embedded systems.

The SG-M35 integrates a high-reliability pressure sensing element with digital signal conditioning electronics, providing stable and linearized pressure outputs even under vibration, temperature fluctuations, and electrical interference.

Its compact structure and multiple pressure types (gauge/absolute/sealed) enable seamless integration into vehicle systems, industrial machines, pneumatic/hydraulic modules, and aviation support equipment.

With digital output options and a stable long-term drift performance, SG-M35 delivers dependable, noise-immune measurement suitable for mission-critical onboard monitoring.
