The key role of pressure sensors in window cleaners
Adsorption system pressure monitoring
Since window cleaners need to rely on adsorption to fix on the glass surface, adiabatic pressure sensors can monitor the working status of the adsorption system in real time. By accurately measuring the adsorption pressure, it ensures that the device maintains a stable adsorption force in different air pressure environments to avoid the risk of slipping.
External environment interference regulation
wind force changes have a direct impact on the adsorption effect of the window cleaner. El digital pressure sensor can accurately capture the pressure changes and transmit the data to the control system in real time through the I2C interface, so as to timely adjust the adsorption strategy and ensure the normal operation of the equipment.
Cleaning Brush Head Contact Pressure Control
In order to avoid scratches or incomplete cleaning of the glass surface by the cleaning brush head, the pressure sensor is used to detect the contact pressure of the brush head. The digital sensor can adjust the cleaning force in real time through precise data feedback to achieve uniform and non-destructive cleaning effect.
Safety Alarm MechanismWhen
the pressure sensor detects that the adsorption pressure is below the safety threshold, the system immediately triggers an alarm and takes emergency stopping measures. With the high-speed transmission of the I2C interface, the system is able to respond and execute the safety strategy in a very short time.
