The pressure transmitters of the 21Y series have no internal seal and a high insulation voltage of 300 VDC, and are extremely resistant to environmental influences. The sophisticated compensation circuit makes it possible to specify a narrow total error band. A wide range of pressure connections and electrical connections are available to choose from.


  • Compensated over the entire temperature range • Compact design for space-critical applications
  • Robust stainless steel housing
  • High long-term stability


  • Insulated and encapsulated piezoresistive pressure sensor • Fully welded design with no internal seals
  • Direct analogue signal path with high bandwidth
