We focus on the global market, have rich experience in exporting bus and truck parts, provide services to distributors and fleet operators, and provide tailor-made solutions to meet different needs.
Q1: What is the primary function of this high-precision air pressure sensor in Nanjing King Long new energy buses? A1: This sensor is tasked with precisely monitoring air pressure in key systems such as the brake air reservoirs. By providing accurate and real-time pressure data to the vehicle's control system, it plays a vital role in ensuring the safety and reliability of bus operations.
Q2: How can I confirm this pressure sensor is compatible with my Nanjing King Long new energy bus? A2: This product is engineered as a direct replacement part for specific Nanjing King Long new energy bus models. To guarantee a perfect fit and optimal performance, please verify that your vehicle requires part number QG2221E1-L654M3.
Q3: Why is this sensor described as "high-precision," and what are the benefits? A3: It is designated as "high-precision" due to its ability to provide accurate and reliable pressure measurements. High precision is crucial for the proper functioning of systems like braking. This ensures that control decisions are based on highly accurate data, enhancing overall system performance and safety. Some specialized pressure sensors can achieve high comprehensive accuracy, for example, down to ±0.3% or even ±0.25% in certain applications.
Q4: Is this sensor built to last in the demanding environment of a bus? A4: Yes. We focus on the durability of our products. It is designed to withstand the vibrations and temperature variations common in commercial vehicle operations. Features such as a wide operating temperature range (some sensors can operate from -40°C to 125°C) and the use of robust materials like stainless steel housings contribute to its long-term reliability and help minimize vehicle downtime.
Q5: What about the output signal and electrical characteristics? A5: This sensor is designed for easy integration into the vehicle's electrical system. It typically provides a stable analog output signal (such as 4~20mA current loop or a voltage signal) for reliable data transmission. Always refer to the product's datasheet for the specific output type and electrical requirements of PN: QG2221E1-L654M3.
Q6: Is professional installation recommended? A6: While it is designed as a direct replacement part, we highly recommend that installation is carried out by a qualified technician. Proper installation is critical to ensuring accurate readings, system integrity, and safety.
