High Line/Low Differential Pressure Measurement
Standard Features
Ranges from 5” H2O through 30 psi
1,000 psi over-pressure protection either side
316L SS wetted parts
Stability less than ± 0.25% per annum
Designed for High Static/Low DP applications
The P531 differential pressure transmitter is designed for End
Users and OEMs where high overpressure protection (1000 psi)
ruggedness, high performance, and reliability are required at a
competitive price. This product is modular and is configurable to meet
our customers' exact needs.
Manufactured for extended life cycle
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.
Entirely welded 316L SS pressure cavities
The P531 pressure port's all welded 316 SS ‘O’-Ring free design
makes it ideal for high cyclical applications, capillary filled systems, or
applications where a guaranteed leak free system is needed.
Line pressure / overpressure to 2,000 psi
Accuracy to ± 0.1% FSO
Low power consumption (less than 2 mA)
