Dwyer Series 636D Fixed Range Differential Pressure Transmitter (636D-0, 636D-1)

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.
