Applications and features
Adopt high-precision MEMS sensor and digital technology to detect
positive pressure, negative pressure or differential pressure.It can be widely used to measure the pressure of fans and blowers,
filter resistance, wind speed, pressure drop caused by furnace
ventilation and orifice plate, liquid level of foaming system and
pressure of supercharger or hydraulic system.
It can be used to monitor blood and respiratory pressure on medical
equipment Applicable to embedded installation, plane installation
and other installation methods
