Explosion‑Proof Digital Pressure Controller

What It Does

The YD‑4 combines pressure measurement, digital display, analog output, and alarm control in one explosion‑proof device. No need for separate gauges, transmitters, or switches.

Key Features (Simple)

• Ex d II C T6 Gb explosion‑proof – safe for Zone 1 & Zone 2 hazardous areas

• All‑in‑one design – measure, display, transmit, and control

• Field adjustable – change range and alarm points on‑site without factory tools

• Multiple outputs – 4‑20mA, 0‑5V, 0‑10V, RS485 (Modbus), and HART (optional)

• 2‑channel alarm control (customizable for more points)

• Rugged housing – cast aluminum, dust/water resistant

• Clear 4‑digit LED display – easy to read at a glance

Basic Specifications (No Table)
