The transmitters of the 985-Modbus series are used to measure differential pressure, volume flow or flow velocity and pressure. The measured value can be output and the parameterization on the device can be done via the Modbus RTU data interface.

Applications
Monitoring of gaseous, non-combustible and non-aggressive
media.
Possible usage areas are:
· Building automation and air conditioning systems
· Overpressure measurement in clean rooms and laboratories
· Measurement of constant pressure in VAV applications
· Dynamic filter and ventilator monitoring

Communication
The digital signal Modbus enables direct connection to control /
regulating systems.
