Tel-Tru P141 Specifications

P141

Heavy Duty Pressure Transmitter

Precision Grade- For Harsh Environments

Designed for the hazardous locations

P141 Pressure Transmitter is designed for use in
hazardous locations. The entirely welded 316LSST

construction is hermetically sealed.

Low Cost

Manufactured for reliable service in aggressive environments

The P141 is manufactured for reliability in aggressive environments
where other transmitters fail. Automated weld procedures,

extreme environmental burn in, and the mounting of electronics
to withstand the most severe shock and vibration applications assure
safety and reliability. Additional EMI/RFI ltering with surge protection

add to the performance of the P141.

Alternate materials for service in corrosive environments

For corrosive environments where 316L or 15-5 SS are not best
suited, the P141 is available in Hastelloy C276, C22 or Inconel 718.

Certication

Each P141 transmitter is shipped with a NIST traceable

calibration certicate.

CE
