Features
SS422 series flush mounted pressure transmitter are designed for applications where clogging is an issue. Thanks to a semi-flush construction, the pressure diaphragm is exposed, in direct contact with the medium, with reduced dead volume. As an economical version, the material used for the process connection is stainless steel 304, and it adopts an O-ring sealed structure inside the process connections.
SS422 series has a wide pressure range, covering from 1 bar up to 1000 bar, and available with analog current output and voltage output such as 4- 20mA, 0- 20mA, 0-3V, 0-3.3V, 0-5V, 0-10V, 0.5- 4.5V, 1- 5V, ect. Meanwhile, the transmitter has an abundance of processes and electrical connections. The diversity of products gives SS422 an extensive range of applications, such as water, food, beverage, and pharmaceutical, at a competitive price.
