AO910PD battery powered on-site pressure display instrument

The on-site pressure display device is an on-site installed pressure unit that is used in conjunction with industrial pressure sensors. As a new generation of temperature measuring instrument, it can be widely used in industrial sectors such as metallurgy, petroleum, chemical, power, light industry, textile, food, and scientific research.

FUNCTION PRINCIPLE

The pressure sensor converts the measured pressure into an electrical signal. After 18 bit A/D acquisition, the pressure value is corrected using the multi segment line approximation method and displayed on the LCD.

main features 

1. Adopting silicone rubber or epoxy resin sealing structure, it is shock resistant, moisture resistant, and suitable for installation and use in harsh on-site environments.

2. On site installation not only saves expensive compensation wire costs, but also improves anti-interference ability.

3. High precision, low power consumption, wide temperature range for use, stable and reliable operation.

4. Widely applicable, it can form an integrated on-site installation structure or be installed as a functional module in detection equipment and instrument panels for use.
