-
Precision Measurement:
0.5% FS accuracy for reliable differential pressure monitoring across liquid, gas, and vapor media. Fixed range configurations (636D-0, 636D-1) tailored to specific application needs.
-
Durable Construction:
NEMA 4X-rated 316 stainless steel enclosure resists corrosion, dust, and water ingress. Welded construction ensures integrity in harsh environments (e.g., offshore, chemical plants).
-
Wetted Materials:
316L stainless steel components compatible with most industrial fluids and gases. Reduces risk of material degradation or contamination in process systems.
-
Safety & Compliance:
CSA-approved explosion-proof for Class I, Division 1 hazardous areas (Groups B, C, D). NACE compliance for offshore and corrosive environment applications.
-
Output Versatility:
Standard 4-20 mA signal for long-distance transmission; optional 1-5 VDC for local systems. Loop-powered design simplifies integration with PLCs, SCADA, and control panels.
-
Environmental Resilience:
Operates in extreme temperatures and harsh conditions with minimal maintenance. Suitable for outdoor installations or dusty/particulate-laden environments.
