Oil and natural gas equipment requires pressure sensors to be reliable and able to withstand extreme environmental and pressure conditions. The QTQ100 intrinsically safe explosion-proof pressure transmitter is packaged with a metal-based pressure-sensitive chip independently developed and produced by our company. The wetted parts are 17-4PH Stainless steel material can provide a variety of electrical and pressure connections and electrical output. The manufacturing process adopts the most advanced automation equipment to ensure consistent quality and performance of the sensor. It can provide 0.2% in the pressure range from 0.5MPa to 250MPa

The comprehensive accuracy of FS, 0.5%FS and 1%FS has the advantages of long-term fatigue resistance, wide temperature range, impact resistance and high reliability. It can accurately measure even under the most severe conditions and is suitable for various gases , Liquid pressure measurement. The pressure transmitter has a compact structure and is an ideal choice for installation in tight spaces in hazardous areas.

QTQ100 type is current output type

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 QTQ100 series pressure sensor 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.
