PBMN pressure transmitter uses piezo-resistive and thin-film technology

November 29, 2010. 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 < 0.4 % F.S., the sensor provides 0.1 % F.S. of long-term stability. The choice of output signals includes 4…20 mA as well as several types of voltage. With its wide measuring range and high overpressure resistance, the PBMN is qualified for a very broad spectrum of applications. The PMBN is easy to configure using Baumer’s programming device FlexProgrammer 9701.

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.
