P143

Certified for Hazardous Locations

Approved for hazardous locations

The P143 Pressure Transmitter is d esigned and approved
for use in hazardous locations. The P143’s entirely welded 316L SST
construction is hermetically sealed making it ideal for the worst of
pressure applications. CSA/CUS Explosion Proof certified for Class I
Div 1 and Class I Div 2 Groups A, B, C, D.

Manufactured for reliable service in aggressive environments

The P143 is manufactured for reliability in aggressive environments
where other transmitters fail. Automated weld procedures,
extreme environmental burn in, and t he mounting of our electronics
to withstand the most severe shock and vibration applications are all
geared toward safety and reliability. Additional EMI/RFI filtering with
surge protection add to the performance of the P143.

Alternate materials for service in corrosive environments

For corrosive environments where 316L or 15-5 SST are not best
suited, the P143 is available in Hasteloy C276, C22 or Inconel 718.

NIST

Each P143 transmitter is shipped with a NIST
traceable calibration certificate.
