Huba 699M Series – Differential Pressure Transmitter


  • High accuracy
  • Available with one or two differential pressure sensor units
  • Up to two universal inputs for 0 … 10 V or passive temperature elements
  • Two 0 … 10 V analog outputs
  • Simple installation
  • Reduced wiring effort through decentralized node

Huba 699M Series pressure transmitter is primarily utilized for air and neutral gas monitoring purposes. This unit is optionally equipped with one or two differential pressure sensors, enabling observation of differential pressure or volumetric flow at two distinct points within the system. Such versatility renders the 699M ideal for a wide array of tasks within the HVAC industry. Communication occurs via Modbus® RTU, and the unit boasts two universal inputs along with two analog outputs. By linking additional sensors and controlling actuators, users can utilize the unit as a decentralized node for existing controllers, thereby expanding inputs and outputs while reducing installation expenses. The sensors employed by this unit are based on Huba Control AG’s unique and well-established ceramic strain-gauge beam technology.
