P521 Differential Pressure Transmitter
Brand: Tel-Tru Manufacturing Co.Every P521 is built using advanced manufacturing techniques to ensure symmetry between the HI and LO ports.
Symmetry, along with automated welding procedures and extreme environmental burn-in give Tel-Tru's differential pressure products excellent performance and reliability over time and at high elevated line pressure.
The P521 pressure ports all welded 316L Stainless Steel ‘O’-Ring free design make it ideal for high cyclical applications, capillary filled systems, or applications where a guaranteed leak free system is needed.
