QTQ401/402 weighing pressure sensor
The QTQ400 series weighing pressure sensor is packaged with a metal-based pressure-sensitive chip independently developed and produced by our company. It is designed for the weighing of hydraulically loaded equipment such as loaders, forklifts, forklifts, and excavators. The accuracy level of the pressure sensor can reach 0.2% FS, which is very suitable for dynamic and static measurement tasks. It can weigh objects in the excavator bucket or determine the weight on forklift forks. It can be used as a weight measurement in trade applications. The product has a wide range of output forms, electrical and pressure connections, impact resistance, high reliability, and high temperature resistance. It can work stably for a long time at -40 to 105°C, and is suitable for most applications.
QTQ401 mV signal
QTQ402 type with conditioning
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 QTQ400 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.
