Dragino PS-LB/LS-D LoRaWAN Differential Pressure Sensor

The Dragino PS-LB/LS-D sensor is a high-precision LoRaWAN differential pressure sensor designed for monitoring pressure differences in HVAC systems, filters, liquid levels, and other industrial applications. It delivers reliable and accurate measurements across a wide range of pressures, from 100Pa up to 10KPa, ensuring critical systems operate efficiently and safely.

This sensor offers flexible power options for long-term deployment: the PS-LB-D model runs on an 8500 mAh Li/SOCl₂ battery, while the PS-LS-D includes a 3000 mAh Li-ion battery with an integrated solar panel for near-continuous operation. With LoRaWAN connectivity, Bluetooth v5.1 configuration, and over-the-air firmware updates, the Dragino PS-LB/LS-D sensor provides remote management, low-power operation, and robust performance in harsh or hard-to-reach environments.

Overview

The Dragino PS-LB/LS-D sensor is a high-precision LoRaWAN differential pressure sensor. It measures the pressure difference between two points, making it ideal for HVAC systems, air filters, liquid tanks, and industrial pipelines. By monitoring pressure changes, it helps prevent equipment failure, optimize energy use, and reduce maintenance costs.

High Accuracy Across Applications

The sensor supports multiple pressure ranges from 100Pa to 10KPa, which makes it suitable for both sensitive airflow systems and high-pressure pipelines. It combines robust piezoresistive sensing with high-resolution electronics to provide accurate readings under varying temperatures, humidity levels, or environmental conditions.

Flexible Power Options

The PS-LB-D model uses an 8500 mAh Li/SOCl₂ battery that can operate for several years depending on reporting intervals. The PS-LS-D model includes a 3000 mAh Li-ion battery with an integrated solar panel, offering near-continuous operation in remote locations. Both models feature ultra-low-power consumption to maximize battery life.

Easy Wireless Configuration

The sensor communicates via LoRaWAN v1.0.3 Class A, providing long-range and low-power data transmission. Users can configure the device remotely through LoRaWAN downlinks or locally via Bluetooth v5.1. Additionally, the sensor supports over-the-air firmware updates, keeping it up to date without requiring physical access.

Rugged and Reliable Design

Housed in a weather-resistant enclosure, the Dragino PS-LB/LS-D sensor withstands harsh indoor and outdoor conditions. Its combination of precision measurement, flexible power options, long-range wireless connectivity, and robust design makes it ideal for industrial automation, smart building monitoring, environmental projects, and water management systems.
