Compact pressure sensor now with npn circuit

May 21st, 2012, Published in Articles: EngineerIT

The new pressure sensor from Ifm Electronic’s PQ series is especially suitable for pneumatic applications in robotics and handling. Using a specially sealed measuring cell, this sensor precisely and reliably detects the pressure in the vacuum and overpressure range. The piezoresistive silicon cell measures, depending on the selected unit, between -1 and 10 bar or -1 and 1 bar. Due to the special sealing of the measuring cell, the pressure sensor is insensitive to liquids such as condensed water and deposits that might occur in the system. High overload resistance and an accuracy of ≤ 0,5 % are further positive features. The slanted four-digit display can be electronically rotated by 180° and conveniently read at a distance, from the front or from above. The display colour is selectable: red or green. Green indicates an acceptable range while red indicates when the switching point is exceeded or not reached. Two programmable switching outputs or one switching output and one diagnostic output provide flexible use.
