69XXN – Wireless LoRaWAN Pressure Transducer

The certified explosion-proof 69xxN sets a new standard for high-precision wireless pressure monitoring. By eliminating the need for complex wiring, it enables reliable remote monitoring via LoRaWAN® and offers effortless configuration through Bluetooth® Low Energy. Engineered for versatility, the 69xxN accurately measures both liquid and gas pressures — even in demanding applications involving contaminated water, steam, or mildly corrosive fluids.

Its robust 316L stainless steel wetted components ensure long-term durability, with no O-rings or organic materials exposed to the media. Designed for the toughest environments, the 69XXN is weatherproof and exceeds the latest CE requirements for heavy industrial use — delivering dependable performance wherever it’s needed.

The pressure sensors are HazLoc certified for the use in explosive atmospheres for the United States, Canada, ATEX, IECEx.
