Pressure Transmitter for High Temperatures

Baumer’s (Germany) PBSN general purpose pressure transmitter series can now be used in media temperatures up to 150 °C. This is made possible by means of a cooling neck. The sensor, which is based on a thick film ceramic measuring cell, is also suitable for applications with aggressive media. This qualifies the transmitter for a wide variety of uses in fields as diverse as the petro-chemical through to food and beverage industries.

Modularly constructed, the PBSN pressure transmitter series offers a flexible design to suit different customer needs, ensuring that their pressure measurement applications are served with an accurate, reliable and cost-effective product. Based on thick film technology, the measuring cells are suitable for gauge as well as for absolute pressure and cover a measuring range from -1…0 bar up to 0…600 bar. The standard accuracy is at 0.7%, or optionally 0.5%, of the full scale.

The thick film technology is based on a ceramic support material for the pressure measuring cell. This material is chemically neutral and compatible with most media, including very aggressive ones. These measuring cells are also characterised by excellent long-term stability and outstanding measuring performance in terms of linearity and hysteresis.

A 4…20 mA output signal or voltage output signals are available and all common electrical connections and cable types are offered. The PBSN can be delivered with different process connections made of stainless steel. Moreover, a wide range of gasket ring types are available.
