Baumer PBMR is a fully welded pressure transmitter for railway application that has excellent accuracy and long-term stability up to < 0.1% FS. During the entire temperature operating range, active temperature compensation activated to ensure higher accuracy of the measurement. The sensor element is welded the stainless steel housing that is robust and built for harsh environment.
- Excellent accuracy and long-term stability up to ≤ 0.1% FS
- Active temperature compensation throughout the entire operating temperature range
- Sensor element fully welded to stainless steel housing
- Tested for railway applications according to EN 50155:2007
- Vibration and shock resistant according to EN 61373:1999, 2010 (category 2)
