Wireless data collector has built-in precision ADC, controllable voltage source, world leading low power processor and wireless module. The processor opens the voltage source regularly and closes the voltage source after collecting the pressure data signal. It converts the collected voltage value into the pressure value. When the pressure is greater than the upper limit or less than the lower limit alarm threshold or the pressure fluctuation is greater than the set value, it triggers the terminal alarm and sends the alarm information to the management platform by wireless network.
Sampling time, timing reporting time, alarm threshold and other parameters can be set by users according to their needs.
