Suited for measuring differential pressure of air and neutral, non-corrosive gases, this differential air pressure sensor supports both wall-mounted and embedded installation. Equipped with RS485 output, dual relay alarm channels, IP65 protection, 15-28VDC power input, and a high resolution of 1/2000, it is widely adopted for clean-room, laboratory, and HVAC ventilation pressure monitoring scenarios.
Installation & Structural Features
- Multiple air inlet configurations: Comes with front panel, rear-panel, and side panel air inlet options, perfectly adaptable to diverse field installation layouts for differential air pressure sensor deployment.
- Dual mode mounting capability: Compatible with wall-mounted and embedded installation styles, meeting varied on-site mounting demands for HVAC and clean room pressure measuring projects.
- Flame-retardant ABS enclosure: Constructed from flame-retardant ABS material, offering superior impact resistance and heat resistance to secure inner pressure sensing components under industrial-grade working conditions.
Performance & Functional Features
- Premium imported sensing wafer core: Adopts an imported high-performance wafer core, delivering high measurement accuracy, minimal temperature drift, and exceptional long-term working stability for differential pressure measurement.
- On-site configurable audible visual alarm with built-in buzzer: Integrated buzzer enables audible visual alarm reminders; users are allowed to set and tweak alarm thresholds directly on site without extra auxiliary equipment.
Application
Specially engineered for commercial‑industrial environments, this differential air pressure sensor supports both wall‑mounted and embedded installation. Optimized to measure air and non‑corrosive neutral gases, it performs accurate measurements of positive pressure, negative pressure, and differential gas pressure for diverse ventilation ductworks, air‑conditioning systems, and air‑handling equipment.
