Product Description:
spacer

Designed for many markets/applications. Dylix’s DPL Series DP is a high static—low differential pressure transmitter based on proven capacitance sensing technology. Key feature of the sensing element is its isolation for induced stress which improves performance and long term stability over elevated line pressures.

Manufactured for extended life cycle. Reliability and stability are manufactured into every device using advanced manufacturing techniques. Extended burnin and thermal cycling are just a few extra steps Senex utilizes to ensure performance over time.

Entirely welded 316L SST pressure cavities. The DPL comes standard with 316L SST sensing diaphragms and process flanges to handle most aggressive fluids. Hasteloy C276 is optional.
