WSLRWEX-PPS is an integrated LoRaWAN process pressure sensor with Ex d approval, suitable for installation in Zone 1, Zone 2, or safe zones. It offers various types of pressure measurements, including Gauge, Absolute, and Sealed Gauge, with a range of -1 to 1000 bar. The sensor boasts high accuracy and stability. Its ultra-low-power design and intelligent firmware enable it to operate for up to 10 years on a single battery, depending on the configuration. The WSLRWEX-PPS supports all global LoRaWAN frequency bands and can also be configured to operate in P2P-LoRa mode, allowing direct data transmission to a P2P-LoRa mode end device. This versatile sensor is ideal for monitoring pressure in applications such as oil pipelines, gas pipelines, LPG tanks, and CNG tanks.
