The pressure transmitter 699M is used primarily for the monitoring of air and neutral gasses. The unit is optionally available with one or two differential pressure sensors, which allows the observation of differential pressure or volumetric flow at two individual points in the system. This makes the 699M ideally suited for a multitude of tasks in the HVAC industry. The 699M communicates via Modbus® RTU and features two universal inputs in addition to two analog outputs. The linking of further sensors and control of actuators offers the option of using the unit as a decentralized node for existing controllers, extending in- and outputs, and lowering installation costs. The sensors utilized by the unit are based on the unique and well-proven ceramic cantilevered beam technology developed by Huba Control AG.
