product description

The QTQ501 compact industrial pressure sensor is packaged with a metal-based pressure-sensitive chip independently developed and produced by our company, which can provide reliable pressure measurement even in harsh environments. The product has a compact and reliable structure, good electromagnetic compatibility, impact resistance and high temperature resistance. The measurement range is from 0.5MPa to 100MPa. There are multiple comprehensive accuracy options of 0.2% FS, 0.5% FS and 1% FS, which can be in the range of -40~ Long-term stable operation at 105°C makes the pressure transmitter meet the most stringent industrial requirements. 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.

Core capacity advantage

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

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.

strong and sturdy

The QTQ501 compact pressure sensor adopts an all-welded stainless steel compact design, 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.
