Dylix Corporation DPL Series
Process Differential Pressure Transmitters
Characteristics:
- 316 SST diaphragms and flanges
- External zero and span adjustments
- ±0.2% STR Static Accuracy
- Hasteloy C-276/ Monel diaphragms
- Hart Protocol
- Local display
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.
