QYB109 Intelligent pressure gauge is made with entire electronic structure, and uses battery as power supply. It is easy for field installation. QYB109 intelligent pressure gauges are using high accuracy piezoresistive pressure sensors, which is located in the front end of QYB109. The output signal of the pressure sensor is processed and amplified by high accuracy and low temperature coefficient amplifier, and then transferred to A/D switch to transform digital signal which can be processed by microprocessor. After processing operation, the pressure gauge will demonstrates the actual value of the pressure by LCD indicator. QYB109 has automatic turn-off function in 1~15min.

The operation of QYB109 is very simple, and the adjustment of this gauge is easy, safe and reliable. QYB109 inelligent pressure gauge is widely used in such industries as water and electricity, running water, petroleum, chemical, and machinery, for the measurement and demonstration of fluid medium's pressure.
