The Huba Control differential pressure sensor series HC699 is designed for precise measurement of very low pressures and vacuums in technical and process applications. Typical uses include filter monitoring, ventilation, air flow, or pressure conditions in pipelines. The device allows easy setting of the measuring range and output signal via DIP switches and offers a button for zero point reset, enabling compensation for installation deviations or pressure changes after installation. Recommended installation is vertical with pressure connections at the bottom for condensate drainage.
