["The sensors of the Dragino PS-LB series are LoRaWAN pressure sensors for Internet of Things solutions. PS-LB can measure air, water pressure and liquid level and upload the sensor data to the LoRaWAN IoT server via radio. PS-LB series sensors include thread installation and immersion types, they support different pressure ranges, which can be used for different measurement needs. The LoRa wireless technology used in the PS-LB allows the device to send data and achieve extremely long ranges at low data rates. It offers spread spectrum communication with extremely long range and high interference immunity with minimal power consumption. PS-LB supports BLE configuration and over-the-air OTA updates, making it easier for users to use. PS-LB is powered by an 8500mAh Li-SOCI2 battery, designed for long-term use of up to 5 years. Each PS-LB is pre-installed with a set of unique keys for LoRaWAN registrations. Register these keys on the local LoRaWAN server and the connection will be established automatically after power on. This sensor is intended for measuring air pressure in pipes. To measure water pressure in containers, please use item 217626 This sensor has a thread installation probe with a G1/4 thread and the following features:", "Hersman pressure transmitter", "Measuring range: 0-0.6 MPa, for other measuring ranges please contact our sales department", "Accuracy: 0.2% F.S", "Long-term stability: 0.2% F.S ±0.05%", "Overload 200% F.S", "Zero temperature drift: 0.03%FS/°C(=100Kpa), 0.02%FS/°C(>100Kpa)", "FS temperature drift: 0.003%FS/°C(=100Kpa), 0.002%FS/°C(>100Kpa)", "Storage temperature: -30°C~80°C", "Operating temperature: -20°C~60°C", "LoRaWAN 1.0.3 Class A", "Ultra-low power consumption", "Measurement of air, gas or water pressure", "Different print ranges available", "Thread installation type or immersion type", "Battery level monitoring", "Bandwidths: EU868", "Supports Bluetooth v5.1 and LoRaWAN remote configuration", "Supports wireless OTA update firmware", "Uplink at regular intervals", "Downlink to change configuration", "8500mAh battery for long-term operation", "MCU: 48Mhz ARM", "Flash: 256KB", "RAM: 64KB", "Supply voltage: 2.5v ~ 3.6v", "Operating temperature: -40 ~ 85°C", "Frequency range Band 1 (HF): 862 ~ 1020 MHz", "Max +22 dBm constant RF output vs", "RX sensitivity: up to -139 dBm", "Excellent blocking immunity", "Range: 0~20mA", "Accuracy: 0.02mA", "Resolution: 0.001mA", "Range: 0~30v", "Accuracy: 0.02v", "Resolution: 0.001v", "Li/SOCI2 non-rechargeable battery", "Capacity: 8500mAh", "Self-discharge: <1% / Year @ 25°C", "Max. continuous current: 130mA", "Max. current: 2A, 1 second", "Sleep Mode: 5uA @ 3.3v", "LoRa Transmit Mode: 125mA @ 20dBm, 82mA @ 14dBm"]
