Dwyer Series 636D Fixed Range Differential Pressure Transmitter (636D-0, 636D-1)
Product Introduction
The Dwyer Series 636D Fixed Range Differential Pressure Transmitter is a rugged, high-accuracy instrument designed for measuring pressures of liquids, gases, and vapors in demanding industrial environments. With a 0.5% full-scale (FS) accuracy and standard 4–20 mA output (optional 1–5 VDC), it ensures precise data transmission for process control. Housed in a NEMA 4X-rated 316 stainless steel welded enclosure, the transmitter withstands harsh conditions, while all 316L wetted materials ensure compatibility with most media. CSA-approved for explosion-proof use in hazardous locations and compliant with NACE standards for offshore applications, the 636D combines reliability with safety for critical industrial measurements
Product Features
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.
