Model TXI7850 Moisture Resistant I/P Pressure Transducer

Brand: Fairchild Industrial Products
Rotork Fairchild's TXI7850 I/P Pressure Transducer operates under the same basic principles as the TXI7800, yet improves upon the design. By encapsulating and otherwise protecting the critical components, Fairchild designed the Explosion proof TXI7850 I/P Pressure Transducer to be highly resistant to moisture within the supply air lines. 

Available in both standard and extended range configurations, the TXI7850 delivers vibration, shock and moisture resistance in output pressures up to 0-120 psi [0-8.0 BAR], (0-800 kPa). It carries full Agency Approvals, including FM, CSA and ATEX certifications.
Features
  • 18 available output ranges
  • Accuracy as low as 0.15%
  • Moisture Resistant
  • Field selectable outputs in three pressure ranges
  • Field reversible feature
  • Does not contain copper-based metals
  • Optional version approved for use with Natural Gas or Industrial Methane supply media
  • Explosion-proof NEMA 4X, IP65, Type 4 enclosure
  • Canadian Registration Numbers (CRN) certifications
  • FM, CSA and ATEX approvals

Rotork Fairchild's TXI7850 I/P Pressure Transducer operates under the same basic principles as the TXI7800, yet improves upon the design. By encapsulating and otherwise protecting the critical components, Fairchild designed the Explosion proof TXI7850 I/P Pressure Transducer to be highly resistant to moisture within the supply air lines. 

Available in both standard and extended range configurations, the TXI7850 delivers vibration, shock and moisture resistance in output pressures up to 0-120 psi [0-8.0 BAR], (0-800 kPa). It carries full Agency Approvals, including FM, CSA and ATEX certifications.
