The QTQ611 series rail pressure sensor is packaged with a metal-based pressure-sensitive chip independently developed and produced by our company, which can provide reliable pressure measurement even in harsh environments. The product is an integrated structure design, good long-term stability, wide temperature range, and high precision.

The product is installed on the common rail pipe, which can accurately measure the real-time fuel pressure in the common rail pipe in the shortest time, and convert the fuel pressure in the rail into a voltage signal and transmit it to the ECU at the same time, so as to realize the accuracy and timing of fuel injection. Stable control.

With an annual production capacity of 6 million cores, it has completely broken the pattern of foreign monopoly of the cores.

The first packaging line with an annual output of 2 million pressure sensors was successfully put into production. Follow-up will continue to expand production.

Qitai has the only domestic energy-producing metal-based pressure-sensitive chip production line, a 100-level purification workshop, and a fully automatic binding machine. It fully complies with the ISO9001 quality management system to ensure product quality and consistency. The company is well aware of the importance of quality in product applications, and for this reason we have been doing everything possible to improve product quality. For engineers, the worst thing is to stop work because of quality problems. Qitai attaches great importance to this issue and makes unremitting efforts for it. We promise to provide you with the greatest quality assurance. Qitai uses sputtering film technology, complete products and 100% final inspection quality assurance measures to ensure that customers will no longer be Worry about quality problems.

The QTQ611 series rail pressure sensor adopts a compact design of fully welded stainless steel, which can effectively protect the sensor under harsh working conditions. The electrical connector has a protection level of IP65 and a solid internal structure design to ensure that the sensor can work normally in a high vibration environment.
