P531 Differential Pressure Transmitter
Brand: Tel-Tru Manufacturing Co.The P531 differential pressure transmitter is designed for End Users and OEMs where high overpressure protection [psi: 1,000 (kPa: 6,895, bar: 68.95)] ruggedness, high performance, and reliability are required at a competitive price.
This product is modular and is configurable to meet our customers' exact needs. Every P531 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 P531 pressure port's all welded 316 Stainless Steel ‘O’-Ring free design makes it ideal for high cyclical applications, capillary filled systems, or applications where a guaranteed leak free system is needed.
