Digital Real-Time Air Filter & AHU Pressure Monitoring System
Upgrade your air handling units (AHU), cleanrooms, and filter banks with continuous digital pressure tracking. The Fainlynx FLX-DPT200 Series features a high-precision digital differential pressure transmitter with a built-in backlit LCD display, native RS485 Modbus communications, and optional wireless cloud integration.
Eliminate manual paper logs, prevent premature filter replacements, and get real-time pressure alerts directly to your phone or BMS. Distributed by Signal Transmission (M) Sdn Bhd.
⚠️ Scope of Supply & Gateway Notice:
• All packages are sold on a Hardware Supply-Only basis. On-site cable pulling, duct mounting, and Testing & Commissioning (T&C) are strictly optional services.
• First-Time Cloud Deployments: Wireless cloud packages require a Fainlynx LoRaWAN Gateway. First-time buyers must select the Turnkey Cloud Suite. The Wireless Node Expansion is strictly reserved for existing clients expanding an established Fainlynx gateway network.
Key Features & Benefits
- 📺 Live On-Site LCD Display: High-visibility digital screen shows real-time differential pressure (Pa) directly at the AHU or cleanroom wall.
- 📡 RS485 Modbus RTU Native: Seamlessly integrates with local BMS or wireless IoT transceivers.
- 📱 Automated Cloud Alerts: Pair with Fainlynx Cloud for instant Email notifications when filter pressure drop reaches critical limits.
- 📦 Complete Installation Package: Supplied with a full duct accessory kit including 2m clear PVC pressure tubing, duct mount, and mounting hardware.
System Architecture
Digital Sensing (LCD Display) ➔ RS485 Data Transport (UC100 Node) ➔ Gateway (UG65) ➔ Cloud Analytics (Fainlynx Cloud)
The FLX-DPT200 continuously measures micro-pressure differential across your filter, displaying the exact Pascal value on its front LCD. The integrated wireless transceiver reads data via RS485 Modbus and streams continuous telemetry to Fainlynx Cloud (hosted on secure enterprise infrastructure), plotting degradation trend lines and sending instant alerts before airflow fails.
