PS-NB-D
NB-IoT Differential Pressure Sensor
The Dragino PS-NB/NS series sensors are NB-IoT Pressure Sensor for Internet of Things solution. PS-NB/NS can measure Air, Water pressure and liquid level and upload the sensor data send to IoT platform via NB-IoT network. The PS-NB/NS series sensors include Thread Installation Type, Immersion Type and Food Safety Thread Type, it supports different pressure range which can be used for different measurement requirement. PS-NB/NS supports different uplink methods including MQTT, MQTTs, UDP, TCP or CoAP for different application requirement, and support uplinks to various IoT Servers.

Application guide
Choose the airflow range by deployment scenario

Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.

HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.

Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
