Features description and benefits
Sensor technology
The built-in sensors of the QBM97.. are based on the unique and in HVAC and automotive
industry well-proven ceramic strain-gauge beam technology.
● The accurate sensors with long-term stability for all measured variables are completely
maintenance free, providing cost savings over the whole lifetime of the plant.
● The sensor elements are also suited for demanding applications in the food or
pharmaceutical industry.
Decentralized node via Modbus (RTU) combined with inputs/outputs
The QBM97.. with its Modbus communication interface is a decentralized node, when using
the inputs and outputs for sensors and field devices:
● For example temperature sensors can be linked to the analog inputs, actors can be
linked to the analog outputs.
● Having these elements on the Modbus communication reduces wiring efforts and
installation costs.
Innovative housing design with quick release fasteners
The housing of the QBM97.. comes with quick release fasteners, which can be pushed in by
hand, making screws and tools for opening and closing the sensor unnecessary. This
innovative housing design could be made true due to a patented sealing which is injected
directly during the plastic injection moulding process. A high protection grade of IP54 is
guaranteed, providing a wide range of application areas.
Plug & play M12 connector
The sensor can be ordered with a M12 connector for power and communication for
plug & play connection during installation.
Workflows and 'How to instructions' for the following functions can be found in manual
A6V11478123.
DIP switches for addressing and Modbus line termination
For flexible use and wide range of application the QBM97.. Modbus air pressure sensor with
I/O extension can be addressed via its DIP switches with other controllers than Climatix
controllers.
Push button for automated on-event addressing together with Climatix controllers
The QBM97.. can be paired (addressed) easily and fast with Climatix controllers with the
inbuilt push button for on-event addressing. On-event push button addressing is
implemented in Siemens Modbus sensors and devices for digital air handling unit (AHU),
providing a consistent, easy and fast commissioning process for manufacturers and
installers.
Zero point factory reset
Through push button a zero point and a factory reset can comfortably be done.
Siemens as global technology partner
The QBM97.. is distributed globally via the Siemens sales network. The sensor is tested
according to the major international standards such as EU and RCM conformity, UL
approbation and EAC, making possible a worldwide field of application. Continuous
innovations and development, as well as sustained quality, logistic processes, spare parts
management and customer support make Siemens a valued technology partner.
