QTQ900 digital pressure sensor/transmitter
The core components of the QTQ900 digital pressure sensor/transmitter use the metal sputtering film core independently developed and produced by our company. The electronic components of the product have been strictly tested, with stable performance, high measurement accuracy, strong anti-interference ability, and appearance. The fully enclosed stainless steel structure can meet the requirements of harsh working conditions such as moisture-proof, explosion-proof, anti-corrosion, and dust-proof. The sensor output signal is standard CA Nbus or RS485 data with strong interchangeability. The product has the functions of data collection, data processing, online calibration, etc. The intelligent digital architecture can better help you to measure and control the equipment, reserve a secondary development interface for users, and allow users to re-customize new sensors.
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.
The QTQ900 digital pressure sensor/transmitter 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 IP67 and a solid internal structure design to ensure that the sensor can work normally in a high vibration environment.
