The QTQ600 series high-strength miniature pressure sensor is packaged with a metal-based pressure-sensitive chip independently developed and produced by Hunan Qitai. The product has a compact structure, high natural frequency, wide temperature range, high precision, and is compatible with most oils, even in harsh conditions. It can also ensure reliable pressure measurement under high working conditions. This sensor is less than the size of a dollar coin, and its size is only 22.7 mm high, with an outer diameter of 12 mm. It is easy to install and easy to design and integrate. Product range, accuracy and mechanical structure support customization.

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 binding 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 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.

QTQ600 series pressure sensor adopts 17-4PH stainless steel pressure-sensitive core, corrosion-resistant, full laser welding, exquisite and compact structure design, and the electrical connection is directly led by Teflon wire. The overall protection level reaches IP67. After 107 pressure cycles, it can be tested. The 1.5 times overload ensures that the sensor can work normally in high vibration environments or even harsh working conditions.
