High-precision pressure transmitters
Save as PDF
In the 23SXc series high-precision pressure transmitters, temperature dependencies and non-linearity are precisely compensated for by means of a mathematical model in the microcontroller. With the CANopen interface, Keller offers a highly accurate pressure transmitter that is optimally suited for a wide variety of automation solutions. The fully welded construction without internal seals is suitable for dynamic applications. Only stainless steel is in contact with the media.
