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
