P141 Heavy-Duty Pressure Transmitter

Brand: Tel-Tru Manufacturing Co.

P141 Pressure Transmitter is designed for use in hazardous locations. The entirely welded 316L stainless steel construction is hermetically sealed.

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 filtering with surge protection add to the performance of the P141.

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