Precision Monitoring in Critical Environments


Dragino's Wireless Differential Pressure Sensor is a vital tool for applications requiring precise pressure difference measurements, such as in clean rooms, laboratories, and various industrial settings. This sensor excels in environments where understanding the subtle changes in pressure is crucial for operational efficiency and safety.

Versatile and Reliable The sensor offers multiple models to cater to different needs, including LoRaWAN and NB-IoT wireless transmission options, as well as a range of pressure measurement capabilities. Whether it's for offshore and subsea gas processing or remote heating systems, this sensor ensures accurate and reliable readings.

Optimised for Performance By monitoring the differential pressure, such as before and after a valve in a pipeline, this sensor provides insights into potential issues like partial valve closures or blockages, playing a key role in preventative maintenance and system integrity.

Seamless Telemetry2U Integration Integrated with Telemetry2U's IoT platform, the sensor elevates its functionality. Users receive instant alerts and can access a real-time dashboard for continuous monitoring. The ability to analyse historical data enhances decision-making, ensuring proactive maintenance and system optimisation.



Choose the 12-Month Subscription with Telstra SIM



When you select one of the "12-month IoT Platform Subscriptions", we'll handle all necessary configurations for seamless integration into Telemetry2U's IoT platform. If you also ordered a Telstra 500KB NB-IoT SIM card with your device, That'll also be installed and configured prior to shipment. The SIM card is locked to the device and the data capped at 500KB, so there is no chance of any suprise charges.
