PBSN pressure transmitter for high temperatures

March 21, 2011 // By Christoph Hammerschmidt
Baumer's PBSN general purpose pressure transmitter series has been extended for use in ambient temperatures of up to 150°C. This is made possible by means of a cooling neck.

Designed modularly, 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 very high long-term stability and 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.

The PBSN is implemented using a fully-welded stainless steel housing with a standard IP65 rating, with IP67 available, depending on the type of electrical connection. It is abrasive and chemically resistant which also makes it suitable for numerous general purpose industrial applications in the sectors of pneumatics, energy production, HVAC and automobile industry.

The sensor 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, biotechnology and medical gas as well as food and beverage industries.
