The Dragino PS-LB-D LoRaWAN Differential Pressure Sensor (8500mAh Li/SOCl2 / US915 / -200- 200Pa) is designed to measure the difference in air pressure between two points, which is crucial in various applications such as monitoring the efficiency of valves in pipelines. This sensor is particularly useful in scenarios where it is essential to ensure that the pressure on both sides of a valve is equal, indicating that the valve is fully open and functioning correctly. If a discrepancy in pressure is detected, it may suggest a partial closure or blockage.
This sensor is suitable for both home and industrial environments, including offshore and subsea gas processing, as well as remote heating systems. It operates on the LoRaWAN 1.0.3 Class A protocol, ensuring reliable wireless transmission of data. The device is equipped with an ultra-low power consumption feature, making it efficient for long-term use. It supports a range of pressure measurements from -200 to 200Pa, allowing for versatile application.
The Dragino PS-LB-D sensor is powered by an 8500mAh Li/SOCl2 battery, ensuring extended operational life. It also supports Bluetooth v5.1 and allows for remote configuration via LoRaWAN, providing flexibility in managing the device settings. The sensor can send uplink data periodically or in response to an alarm input, and it supports downlink communication for configuration changes. Additionally, it is capable of wireless over-the-air firmware updates, ensuring that the device remains up-to-date with the latest software enhancements.
Note: Ensure proper handling and installation to avoid damage or inaccurate readings.
