In this exhibition, Qitai Sensing exhibited high-performance pressure-temperature integrated thin-film pressure-sensitive chips and ultra-small intelligent pressure transmitters that have reached the international advanced level. The pressure-temperature integrated thin-film pressure-sensitive chip is developed by Qitai Sensing. Currently, the zero drift is very small, and the temperature effect is minimal. High stability, high reliability, high input impedance, high accuracy, high temperature and high pressure resistance. , A new product with integrated temperature-sensitive resistor.

　　▲Ultra-small intelligent pressure transmitter

The ultra-small intelligent pressure transmitter is a new generation product developed by Qitai Sensing to adapt to the development trend of sensors' intelligence and miniaturization. The outer diameter of the pressure transmitter is only 12.5mm. The product has temperature compensation and linear correction. It can output 0.5～4.5V or 4～20mA or Modbus protocol signals. The accuracy error is ≤±0.1%FS. It is especially suitable for restrictions on installation dimensions. It is used in occasions with high integration, wide ambient temperature range and high precision requirements.
