Electrical Pressure | Precision – Tecsis P3291


  • High accuracy
  • Long-term stability
  • Thermally compensated for 10°C to 60°C temperature range
  • Corrosion resistant stainless steel design
  • With laser welded front-flush diaphragm
  • Serial interface, USB – interface at PC
  • Fast external measurement value processing for data collection to 1kHz ( 3-wire )
  • Compact design

The long-term stability, good corrosion resistance, high protection up to max. IP 67 and mechanical load rating are the basis for the use of the sensor P3291 in harsh industrial environments. The program – controlled temperature compensation system practically eliminates temperature – related measurement errors in the range 0°C to 50°C. The front flush pressure diaphragm avoids zones, in which medium could crystallize or residues could form, thus ensuring trouble-free pressure measurement and hygienic cleaning of the pressure sensor. With a standard accuracy of 0.1% and optional accuracy of 0.05%, these pressure sensors are particularly suitable for use in testing or calibration systems.
