DP Series Differential Pressure Transmitter
High-line Differential Pressure Measurement
Designed for many markets/applications
Dylix’s DP Series differential pressure transmitter is designed for End Users and OEMs where ruggedness, high performance and reliability are required at a competitive price. This product is modular and is configurable to meet our customer’s exact needs.
Manufactured for extended life cycle
Every DP Series 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 Dylix’s differential pressure products excellent performance and reliability over time and at high elevated line pressure.
Entirely welded 316L SST pressure cavities
The DP Series pressure port’s all welded 316 SST O-Ring free design make it ideal for high cyclical applications, capillary filled systems or applications where a guaranteed leak free system is needed.
