YDW39 Wireless Differential Pressure Transmitter

The YDW39 Wireless Differential Pressure Transmitter is an advanced, battery-operated instrument designed for the precise measurement and reliable monitoring of differential pressure, positive pressure, and negative pressure in various industrial and HVAC applications. Its core innovation lies in its integrated wireless communication module (typically LoRaWAN®, NB-IoT, or 4G), which enables easy installation in hard-to-wire locations and seamless integration into IoT (Internet of Things) platforms for real-time data acquisition and analysis. This device is engineered for high accuracy, long-term stability, and minimal maintenance, making it an ideal solution for modern, smart building management and industrial automation systems.

Key Features

• Wireless Connectivity: Transmits data over long distances using low-power wireless protocols (e.g., LoRaWAN®), eliminating the need for costly cabling.
• Long Battery Life: Ultra-low power consumption design allows for several years of operation on a single internal battery.
• High Accuracy: Provides precise and stable pressure readings critical for system monitoring and control.
• Robust Construction: Often features a stainless steel sensor and housing, suitable for demanding environments.
• Easy Installation: Compact and lightweight design allows for flexible mounting. Configuration is typically done via a mobile app or PC software.
• Remote Monitoring: Data is accessible through cloud-based platforms, enabling remote configuration, alarm setting, and historical data analysis from anywhere.

Technical Specifications

Typical Applications

The YDW39 is versatile and is commonly used in scenarios where wired power and signal lines are impractical or too expensive to install.

• HVAC Systems: Monitoring filter clogging (dirty filter alarms) in air handling units (AHUs), measuring airflow across fans and coils, and verifying VAV (Variable Air Volume) system operation.
• Cleanrooms & Laboratories: Ensuring stable pressure differentials between rooms to prevent cross-contamination.
• Industrial Processes: Monitoring pressure drops across industrial filters, pumps, and flow equipment
• Energy Management: Building automation systems (BAS) for optimizing energy efficiency based on real-time pressure data.
• Remote Sites: Ideal for monitoring equipment in remote or widely dispersed locations like water treatment plants or pharmaceutical facilities.
