P143 Explosion-Proof Pressure Transmitter
Brand: Tel-Tru Manufacturing Co.The P143 Pressure Transmitter is designed and approved for use in hazardous locations.
The P143’s entirely welded 316L Stainless Steel 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.
Automated weld procedures, extreme environmental burn in, and the 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.
For corrosive environments where 316L or 15-5 Stainless Steel are not best suited, the P143 is available in Hasteloy C276, C22 or Inconel® 718.
