23046479 Pitot tube Allison spare parts

The Allison 23046479 pitot tube, also known as an airspeed tube or airspeed probe, is a core speed and pressure measuring component used in Allison gearboxes and related equipment. It serves as a “precise probe” for monitoring airflow parameters. Its core principle is based on Bernoulli’s equation. It captures the total pressure of the airflow through the front total pressure port and collects the static pressure of the airflow through the side static pressure port. After pressure difference conversion, it accurately obtains key parameters such as airflow velocity and flow rate, providing real-time and reliable monitoring data for the equipment control system. This helps to accurately regulate the operating status and avoid problems such as decreased equipment efficiency, component wear, and downtime caused by abnormal airflow parameters. It ensures smooth equipment operation and reduces maintenance costs and downtime losses.

Core technical parameters:

-Part Number: Allison 23046479
– Material Specifications: Made of high-quality stainless steel (304/316L) or titanium alloy, with a reasonable ratio of alloying elements such as chromium and nickel. The tube surface is polished and passivated to effectively prevent dust and oil buildup and blockage, while also enhancing wear resistance.
– Structure type: Integrated S-type Pitot tube (or L-type, as needed), with a dual-hole structure design. The front end is the main pressure hole (facing the airflow), and the side is the static pressure hole (vertical airflow). The tube body is made with an integrated molding process. Some models are equipped with an electric heating system (nickel-chromium alloy heating element, power 50-100W), which can melt the ice layer within 30 seconds in an environment of -40℃, avoid freezing and blockage, and ensure normal operation in low-temperature environments.
– Accuracy parameters: Measurement range 0-100m/s (air velocity), 0-1.6MPa (pressure), Pitot tube coefficient 0.82-0.86, accuracy class ≤±1.0%FS (compliant with JJG 518-1998 verification procedure), resolution 0.01m/s, response time ≤50ms
– Protective performance: Temperature range -60℃ to 200℃; oil resistance meets GB/T 1226-2010 standard, can withstand corrosion from various equipment oils and contaminants, neutral salt spray test ≥96h, possesses excellent rust and corrosion resistance; anti-clogging design of the pipe body.
– Applicable Scenarios: Dedicated equipment for Allison series transmissions, widely used in commercial vehicles, heavy trucks, construction machinery and other equipment equipped with Allison transmissions. It is used for monitoring airflow speed, pressure and flow in intake systems, ventilation ducts, flues and other parts, undertaking the core tasks of speed measurement, pressure measurement and flow conversion. It can be used for original parts replacement, equipment repair and maintenance, and is suitable for complex working conditions such as high humidity and dust, high and low temperature, high frequency vibration, etc., to help the equipment accurately control its operating status.
