4-Year Durability Test Results of Fuel Sensors

Regular maintenance of fleet telemetry hardware is critical for data accuracy. In a new technical review, Andrey Romanov, Commercial Director of ITALON, demonstrates the condition of a High-Precision Capacitive Fuel Level Sensor after four years of continuous operation, proving that robust engineering significantly lowers Total Cost of Ownership (TCO).

For fleet managers and telematics integrators, the longevity of hardware is just as important as its initial accuracy. Equipment failure leads to data gaps and costly downtime. Addressing the industry need for transparent reliability data, ITALON has released a detailed visual inspection of a sensor removed from a vehicle after 48 months of active service.

Maintenance Checklist: What to Look For

According to Mr. Romanov, even the most durable industrial equipment requires periodic attention. The inspection highlighted three specific areas that technicians must check during routine maintenance:

  1. Security Seals Integrity:
    The inspected unit was missing its security seal. “We can see the seal is already missing. I would put a seal here also,” Romanov notes.
    • Action: Regularly verify that tamper-evident seals are intact to prevent unauthorized calibration changes or fuel theft.
  2. Cable Protection (Heat Shrink Tubing):
    Environmental factors such as UV radiation and temperature cycling can cause protective layers to degrade. In this case, the heat shrink tubing near the connector had dried out.
    • Action: Replace brittle tubing immediately to maintain IP-rated protection against moisture ingress.
  3. Retrofitting and Adapters:
    The review revealed the sensor was installed using an adapter, indicating a retrofit scenario where ITALON hardware replaced a different brand’s unit.
    • Tip: When using adapters for compatibility with existing wiring, ensure all secondary seals are present to avoid “weak links” in the waterproofing chain.

Durability Proven: 4 Years Without Cracks

Despite the minor consumable wear mentioned above, the core structural components of the ITALON sensor demonstrated exceptional resilience. This durability is a testament to the high-quality materials used in production.

  • Cable Integrity: Unlike inferior cables that crack and expose wires to the elements, the ITALON cable remained flexible and intact. “After four years of use, the cable hasn’t even cracked,” Romanov emphasizes.
  • Gasket Performance: The sealing gasket showed no signs of leakage. “Look how well the gasket holds. There are no leaks at all,” the review concludes.

Conclusion: Lowering Fleet TCO

For fleet owners, this inspection confirms that choosing high-quality telemetry hardware reduces long-term costs. While consumables like seals and shrink tubing are part of standard maintenance, the expensive core components of ITALON sensors are built to withstand years of harsh operating conditions.
