Differential pressure transmitter 699M
The differential pressure transmitters of Type 699M are primarily used for monitoring air and neutral gases. The device is available with either one or two differential pressure sensors, enabling the monitoring of differential pressure or volumetric flow at two different points within the system. This makes the 699M ideal for a wide range of tasks in ventilation technology.
The 699M communicates via Modbus® RTU and features 2 analog inputs as well as 2 analog outputs. The ability to connect additional sensors and control actuators allows the device to function as a decentralized node for existing controllers, expanding inputs and outputs while reducing installation costs.
The sensor technology integrated into the device is based on the unique ceramic bending beam technology developed by Huba Control, which has already proven itself millions of times.
- High accuracy and excellent long-term stability due to proven ceramic bending beam technology
- Modbus® RTU interface
- Optionally available with one or two differential pressure sensors
- Up to 2 analog inputs for 0-10 V or passive temperature elements
- 2 analog outputs 0-10 V
- Simple installation
