Product Details
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.

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.
