Passenger comfort and indoor air quality are critical in mass-transit systems where high passenger density can quickly increase CO₂ concentration. Conventional sensors may experience reduced reliability due to vibration, pressure variations, and electrical disturbances encountered in railway environments.
The Nuicon EE8915 is specifically engineered for railway and transportation HVAC applications and complies with EN 50155 railway standards. The sensor continuously monitors CO₂ levels in passenger cabins and driver compartments, enabling HVAC systems to dynamically control fresh-air intake while optimizing energy consumption.
Quickly verify paint thickness for used car assessments, repairs, and quality checks.
Ensure coating specifications are met on structural steel, railings, and metal fixtures.
Perform fast pass/fail checks on production lines and incoming parts.
Confirm coating thickness during application to prevent costly over- or under-application.
We provide the necessary documentation for railway audits and certifications.
Proven performance in high-vibration environments.
We assist with sensor placement and integration into the Train Control Management System (TCMS).
