With the arrival of the summer tourist season, North American Air Tour Company urgently needed an efficient weighing solution to optimize daily operational processes. Its core needs included:
- Weighing data meeting the high-precision standards specified by Transport Canada
- Real-time monitoring and recording of weight data for each helicopter, facilitating archiving and review
- The equipment being able to operate stably in complex outdoor environments (such as low temperatures in mountainous areas and coastal humidity)
- Seamless integration with the company’s existing computerized flight management system
- Ultra-high Precision Weighing Performance: The R530S sensor achieves an accuracy class of ±0.03%, with a repeatability error of less than ±0.02% and a 30-minute creep error controlled within ±0.02%. Even in complex scenarios where the number of passengers, luggage, and fuel loads are constantly changing, it can accurately capture subtle weight differences, fully meeting the strict standards of Transport Canada for weighing aviation equipment. Its multi-beam internal design can effectively counteract the impact of eccentric lateral forces, ensuring stable data acquisition even when the helicopter is not in an absolutely horizontal state, thus solving the measurement deviation problem of traditional equipment caused by the tilt of the aircraft body.
- Adaptability to Extreme Environments: Adopting an all-stainless steel spring element and hermetic welding technology, it reaches IP68/IP69k protection levels, and can withstand high humidity, salt spray corrosion in coastal areas of Vancouver, as well as low temperatures of -20℃ in the Rocky Mountains in winter. Within the operating temperature range of -40℃ to +65℃, the impact of temperature on zero point and rated output is controlled within ±0.002%/℃, ensuring stable measurement accuracy throughout the four seasons.
- Long-term Durability: The fatigue life of the sensor exceeds 1 million cycles of loading, far exceeding the industry average standard of 500,000 cycles. Calculated based on the company’s frequency of weighing each helicopter twice a day, it can serve stably for more than 130 years. The 150% safe load and 200% ultimate load design can cope with sudden overload situations, providing double safety guarantees for the equipment.
- Intelligent Data Management: Real-time data display is achieved through the EM203DL indicator, which supports Modbus-RTU/TCP protocol for seamless connection with the PC terminal, and weighing results can be printed and archived immediately. The system’s built-in temperature compensation function (-10℃ to +40℃) further eliminates the interference of ambient temperature fluctuations on data. Combined with the 4-wire PVC cable (6-meter cable as standard for 1t-30t models), it ensures stable data transmission without packet loss, solving the problem that traditional analog signals are susceptible to electromagnetic interference.
Within one month after the installation of the equipment, the operational status of North American Air Tour Company has improved significantly:
- The pre-flight weighing process was shortened from the original 25 minutes to 15 minutes, with efficiency increased by 40%. During the peak season, the number of daily flight delays was reduced by 3, and passenger satisfaction increased by 28%.
- There were zero data deviations for 30 consecutive days. During a surprise inspection by Transport Canada, it became the first tourist operator in the region to win the “Aviation Safety Management Excellence Award” due to complete and traceable weighing records.
- The equipment maintenance cost was reduced by 60% compared to before: the stainless steel material reduced the annual anti-rust treatment cost, the IP68 protection reduced the failure rate from 15% to 0 during the rainy season, and the 1 million cycle fatigue life design is expected to extend the equipment replacement cycle to more than 10 years (the original equipment required sensor replacement every 3 years on average).
Microtess Technology stood out from numerous suppliers due to its technical accumulation in the field of high-precision digital weighing, as well as the customized services provided by its international trade team (including English operation manuals and 72-hour global response support). The solution perfectly combines the mechanical performance of the R530S sensor with the intelligent management of the EM203DL, meeting both aviation-level safety standards and the actual needs of tourism operations, fully demonstrating the product concept of “high precision, digitalization, and intelligence”.
