Features
SS412 series flush diaphragm pressure transmitter is flat. It is designed to ensure a dead-space free sealing between the process connection and the measuring medium, so the medium will not heap up. The transmitter is specifically suitable for measuring viscous, paste-like, adhesive media. It offers a stable performance, with offset and full-scale output achieved via the latest ASIC technology. It gives an accurate output signal of 4-20 mA. You can also select 0-5 Vdc, 0-10 Vdc, and other analog output signals. The range of pressures is from 0.35 bar up to 600 bar.
SS412 series is a piezoresistive, silicon-based transmitter with a stainless steel isolated structure. The pressure is coupled from an SS316 membrane. The membrane deforms with pressure via a transmission fluid (silicone oil). The modular design of the transmitter allows various electrical connections, output signals, and process connections. So the transmitter meets the requirements of any application.
