• Maximum precision in measuring both low and high pressures
• Combined error of only
• Highly resistant to vibration, shocks, and bumps
• Active temperature compensation within a range of -40…+85 °C

Baumer’s industrial pressure transmitter PBMN achieves maximum precision in measuring both low and high pressures by using different sensors.

For pressures below 60 bar, a piezo-resistive silicon sensor is used. A metal thin-film sensor ideally suited for higher pressures is available for pressures over 60 bar. The robust PBMN pressure transmitter covers measuring ranges from -100…100 mbar to 0…1600 bar. It is available in three classes of accuracy: 0.1 % F.S., 0.25 % F.S., and 0.5 % F.S. Boasting a combined error of only

Both the housing and all wetted parts of the fully welded PBMN pressure transmitter are made of stainless steel. Suited for media temperatures of -40…+120 °C, the transmitter offers active temperature compensation within a range of-40…+85 °C. The PBMN is highly resistant to vibration, shocks, and bumps, and complies with protection class IP65 or IP67, depending on the type of connection.

The PBMN pressure transmitter proves its particular strengths in applications requiring precision over a wide temperature range. Typical fields of application include process engineering, hydraulics, pneumatics, refrigeration, the automotive and heavy vehicle industries, shipbuilding, healthcare, biotechnology, the chemical industry, and energy supply, as well as test benches, pumps, and compressors.
