The KELLER Series33X pressure transmitter provides highly accurate measurement results and is characterized by its excellent long-term stability. By means of a mathematical model, temperature dependencies and non-linearity are precisely compensated for by the microcontroller. The transmitter can be operated via an analogue interface in addition to the RS485 interface. The fully welded construction with no internal seals is particularly suitable for dynamic applications. Thus, only the stainless-steel encounters the measured medium. 

The Series 33X is typically used in engine test benches, mobile hydraulics, industrial applications, automation technology and many more applications.
