WSLRWEX-PPS is the LoRaWAN Integrated Process Pressure Sensor with Exd approval for installation in Zone 1, Zone 2 or Safe Zone, and it has different kinds of measurements, such as Gage/Absolute/Sealed Gage, range -1 .. + 1000 bar, high accuracy, and stability. With Ultra-low-power design and smart firmware allow the sensor can last up to 10 years with a single C battery (depending on configuration). It can support all LoRaWAN frequency bands in the World.
Typical applications are pressure monitoring of oil pipelines, gas pipelines, LPG tanks, CNG tanks, etc.
