Features
The differential pressure transmitters of Type 402 are ideal for detecting small airflows in HVAC systems and for measuring low pressures in the environmental and medical sectors. Sensors specifically developed for each pressure range enable physically accurate and long-term stable measurements. They allow for simple and quick installation, either directly onto a mounting plate or onto a PCB
