The pressure sensor operates under the same basic principles as the TXI7800, but with an improved design. By encapsulating and otherwise protecting key components, Fairchild designed the explosion-proof TXI7850 I/P pressure sensor to be highly resistant to moisture in the supply line. The TXI7850 is available in standard and extended range configurations that provide vibration, impact, and moisture resistance at output pressures up to 0-120 psi [0-8.0 BAR] (0-800 kPa). It has full institutional certifications including FM, CSA and ATEX certifications.
