Features
SS320 series 3.3 V pressure sensor is designed for a 3.3 V power supply and gives a 0 to 3V or 0 to 2.5V analog signal. It adopts a highly sensitive piezoresistive pressure transducer as the sensing part. It is assembled with a high-quality signal processing ASIC, guaranteeing high accuracy, repeatability, and long-term stability. The sensor gives an incredibly stable signal even under high or low pressures, including vacuum. It is well-suited for precision applications in industrial environments for pressures ranging from 0.1 to 1000 bar.
The pressure sensor is made of SS316L wetted parts and has an O-ring sealed internal structure. Based on the combinability of different mechanical and electronic connections, various other pressure sensors are offered and are widely used for multiple pressure measurement applications with media compatible with stainless steel 316L and Viton.
