Features
SS312 series industrial pressure transmitter is an updated version based on SS302 series. The pressure transmitter 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. It gives an incredibly stable signal even in high or low pressures, including vacuum. It is suitable for precision applications in industrial environments for pressures ranging from 0.1 to 1000 bar.
The pressure transmitter is made of SS316L wetted parts and has an O-ring sealed internal structure based on the combinability of different mechanical and electronic connections. We offer a variety of other pressure transmitters. They are widely used for various pressure measurement applications. The media is compatible with stainless steel 316L and Viton.
