Differential pressure transmitter 699M 0 … 500 - 7000 Pa - 1

Differential pressure transmitter Relative and differential pressure transmitter Type 699M 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 strain-gauge beam technology developed by Huba Control AG. + High accuracy and long-term stability via ceramic strain gauge technology + Modbus® RTU interface + Available with one or two differential pressure sensor units + Up to two universal inputs for 0 ... 10 V or passive tempera- ture elements + Two 0 ... 10 V analog outputs + Simple installation, reduced wiring effort through decen- tralized node Huba Control Type 699M | Technical data subject to change | Edition 09/2020
