Flagship CNG & High-Pressure Measurement Systems Designed for Automotive & Industrial Systems
Navigating Norway’s Zero-Emission Transition, Maritime Gas Networks, and Harsh Northern Operating Environments
Norway stands as a worldwide benchmark for environmental stewardship and clean transportation. While electric vehicles dominate light passenger fleet growth, Norway’s heavy transport, maritime fjords logistics, and municipal waste utility sectors rely heavily on Compressed Biomethane (Bio-CNG) and dual-fuel natural gas infrastructures. Operating gas systems under severe Northern European weather requires instrument hardware capable of maintaining accuracy down to -40°C while subject to continuous structural vibration and salt fog exposure.
Norwegian original equipment manufacturers (OEMs), vehicle conversion shops, and offshore gas processing engineers demand pressure instruments that fulfill strict European compliance criteria, including EN 837-1, ATEX directives, and ECE R110 certifications. Pressure gauges integrated into CNG dispensers, mobile fuel cascades, and engine management panels must provide dual outputs: dynamic visual display for field personnel and stable electronic signal transmission (0.5V-4.5V resistive or 4-20mA) for central ECU processing.
Information Gain Deep-Dive: Material Science, Sensor Integration, and Structural Safety Engineering
High-pressure CNG gauges operating up to 400 Bar (5,800 PSI) utilize seamlessly drawn AISI 316L Stainless Steel or Monel K-500 Bourdon tubes. To prevent micro-fissure expansion caused by trace Hydrogen Sulfide ($H_2S$) impurities in raw natural gas, tubes undergo specialized vacuum heat treatment and stress relief annealing.
Modern vehicle dashboards demand zero latency signal conversion. Our OEM CNG gauges integrate a contact-less Hall sensor array or precision ceramic resistive film printed directly onto the movement backplate. This converts physical movement into 0.5V - 4.5V DC or 0 - 90 Ω resistive signals for instant vehicle ECU readout.
Safety in compressed gas containment is paramount. Featuring a solid baffle wall between the measuring element and the dial, combined with a blow-out back panel, our ATEX certified solid-front cases ensure that in the event of an overpressure rupture, high-pressure gas is safely vented away from operator line of sight.

Where Precision Instrumentation Powers Norway's Infrastructure
Municipal bus operators and waste transport fleets in Oslo, Bergen, and Trondheim utilize our 5V/12V resistive CNG pressure gauges. Built with heavy damping components, these instruments withstand intense chassis vibrations, providing accurate dashboard fuel-level indicators despite rapid thermal shifts.
Norway’s coastal ferries transitioning to dual-fuel (CNG/LNG + Battery) rely on our 4" Vibration-Resistant Stainless Steel pressure gauges. Engineered with laser-welded diaphragms and liquid silicone filling, they resist saltwater corrosion and engine room pulses.
High-flow commercial refueling hubs require instantaneous cut-off and pressure monitoring. Our explosion-proof electric contact pressure gauges (0.6 MPa to 40 MPa) trigger emergency shut-off valves when pressure limits are reached, ensuring safe cascade tank management.
