LORAWAN WIRELESS PRESSURE TRANSMITTER
LoRaWAN wireless protocol in June 2024. By connecting to LoRaWAN networks, the Pressure Scout can wirelessly monitor assets in hazardous or general-purpose environments. The Pressure Scout will initially monitor in general purpose areas before expanding its capabilities to Class 1 Division 1 hazardous locations by Fall of 2024. Based on the field proven Pressure Scout, this version with LoRaWAN protocol will address the challenges of monitoring pressure over wide areas by offering a range of up to 15 miles (24 km). The pressure transmitter will offer battery life of up to ten years and measure pressure from vacuum to 20,000 psi (1360 kPa). With LoRaWAN, the Pressure Scout
S
can address those applications where less frequent measurements are suitable but wider coverage is most important. Applications include monitoring critical infrastructure such as municipal infrastructure, gas distribution, and wellheads in urban or widely dispersed environments. “We are excited to broaden our portfolio
with LoRaWAN. This adds to our existing 900MHz and cellular solutions so users can choose the best fit solution for their applications,” says Sandro Esposito, VP Sales & Marketing for SignalFire Telemetry. “The Pressure Scout with LoRaWAN protocol is another example of our expertise to design products that offer reliable data measurement and transmission in an industrial form factor,” says Josh Schadel, GM and CTO for SignalFire Telemetry. “With clever data transmission in our device, we can optimize for battery life while providing more measurements to our users.”

aker Hughes’ Druck hydrogen- rated pressure sensors are designed to offer longer term stability and withstand harsh environments. The hydrogen
pressure sensors can be used in a variety of applications including gas turbines, hydrogen production electrolysis and hydrogen filling stations. Long term exposure to hydrogen gas degrades the performance of a pressure sensor, specifically through hydrogen permeation and embrittlement of the isolation diaphragm, meaning the construction of a hydrogen sensor is key to maintaining accuracy and stability. Baker Hughes’ latest Druck hydrogen pressure sensors apply high-performance barrier coating technology to protect the sensor element from the harsh effects of hydrogen, providing customers with a market leading minimum lifespan of five years across a wide range of pressures.
“Hydrogen plays a key role in the transition to a more sustainable, lower emissions future but also poses challenges for infrastructure and equipment due to hydrogen embrittlement,” said Gordon Docherty, general
manager of Baker Hughes’ Druck product line. “Building on our legacy of leading industrial pressure measurement technology, the release of our new hydrogen technology enables customers to benefit from a pressure sensor that can withstand harsh hydrogen environments for the long term, while also providing advanced levels of accuracy and reliability. This is an exciting breakthrough in the world of pressure measurement.” Building on the popular UNIK5000 family and supremely accurate RPS/DPS8000 Series, Druck has launched two hydrogen pressure sensor ranges, from 700 mbar (10.2 psi) to 700 bar (10,000 psi). Baker Hughes’ advanced technologies and solutions serve the entire hydrogen value chain, from production to transportation and utilisation. The company’s portfolio includes advanced compressors, gas turbines, valves, centrifugal pumps, non-metallic pipes, hydrogen sensors, monitoring and diagnostics including inspection solutions for hydrogen embrittlement in production and storage, as well as clean power solutions to produce power with hydrogen and hydrogen blends.
