The QTQ000 series general pressure sensor is packaged with a metal sputtering film core independently developed and produced by our company. This series of products can provide a comprehensive accuracy of 0.2% FS, 0.5% FS and 1% FS in the pressure range of 0.5 MPa to 250 MPa. It has the advantages of long-term fatigue resistance, wide temperature range, impact resistance, and high reliability. It can measure accurately even under the most severe conditions and is suitable for pressure measurement of various gases and liquids. This product breaks the monopoly of metal sputtering film pressure sensors by foreign manufacturers. The product quality has reached a world-class level, and some parameters are better than similar foreign products, which can completely replace foreign imported products.

It uses a sturdy, fully welded stainless steel shell, with IP65, IP67 protection grades, moisture-proof and moisture-proof. It has a variety of output forms, pressure connectors and electrical connector selections to meet a wide range of application requirements.

QTQ001 accuracy level 0.2%FS

QTQ002 accuracy level 0.5%FS

QTQ003 accuracy level 1%FS

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 a mass-produced metal-based pressure-sensitive chip production line, a 100-level purification workshop, a fully automatic bonding machine, and 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 an engineer, the worst thing is to stop work because of quality problems. Qitai attaches great importance to this problem and makes unremitting efforts to 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 do not Worry about quality problems again.

The QTQ000 series pressure sensor adopts a compact design of fully welded stainless steel, which can effectively protect the sensor under harsh working conditions. The electrical connector protection level reaches IP65, IP67, and has a sturdy internal structure design to ensure that the sensor can work normally in a high-vibration environment.
