Description

This Genuine OEM Thermo King Ultrasonic Fuel Level Sensor (Part Number: 419250 / 41-9250) is an advanced, high-precision electronic monitoring device engineered to safeguard transport refrigeration units (TRUs) from out-of-fuel shutdowns. Utilizing patent-pending ultrasonic waves, this sensor features no moving parts, making it exceptionally resilient against the continuous shock, vibration, and harsh weather cycles common in long-haul shipping environments. It provides continuous, pinpoint-accurate level telemetry straight down to the absolute bottom of the fuel tank across multiple fuel densities and temperatures. By eliminating mechanical float failures, it avoids false warning loops, removes the need for costly manual fuel system priming following run-dry events, and integrates flawlessly with TracKing telematics systems for ultimate remote fleet oversight.
⭐ Key Features & Benefits
  • Solid-State Ultrasonic Technology: Designed completely without internal moving parts to effectively eliminate mechanical wear and float sticking.
  • Bottom-of-Tank Precision: Delivers continuous, highly accurate depth tracking directly to the floor of the reservoir shell.
  • Prevents System Priming Costs: Mitigates unexpected engine flameouts, saving fleets from the labor and downtime of bleeding air out of diesel lines.
  • Industrial Shock Resistance: Housed in a ultra-compact, heavy-duty casing designed to survive aggressive highway road vibrations.
  • TracKing Telematics Ready: Pairs with standard smart microprocessor links to provide real-time dashboard fuel tracking and low-level alarms.
🔧 Uses / Applications
  • Reefer Fuel Tank Upgrades: Upgrades traditional mechanical level-sending rods inside long-range undermount diesel tanks.
  • Smart Fleet Fuel Management: Deployed across transport fleets to track fuel theft, monitor consumption spikes, and coordinate route refuels.
  • Out-of-Fuel Code Resolution: Replaces failing or intermittent stock sensors triggering false empty warnings or engine protection loops.
  • High-Margin Liquidator Surplus: Highly sought-after, premium-tier electronic replacement assembly for fleet service departments and commercial liquidators.
