QTQ801 series special equipment pressure sensor/transmitter

The core components of the pressure sensor/transmitter of the QTQ801 series of special equipment adopt the metal-based pressure-sensitive chip independently developed and produced by our company, and the integrated circuit chip for conditioning also adopts completely independent domestic products to ensure that the product is completely independent and controllable. The electronic components of the product have been strictly tested to ensure the reliability and safety of the product. The product structure design is reasonable, the detection is accurate, the performance is stable, the measurement accuracy is high, the anti-interference ability is strong, and the appearance adopts a fully sealed stainless steel structure, which can meet the requirements of harsh working conditions such as moisture-proof, explosion-proof, anti-corrosion, and dust-proof.

Core capacity advantage

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

3
Packaging capacity advantage

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.

Quality Assurance

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.
