Pressure and differential pressure measuring transducers PREMASGARD® 11D - Modbus
Maintenance-free microprocessor-controlled PREMASGARD® 11D7 - Modbus with Modbus connection, in an impact-resistant plastic housing,
for measuring the differential pressure (max. –7000...7000 Pa) in the air. Incl. connection set ASD-06 (2 m / 78.74 in connecting hose, two pressure
port nipples, screws).

The pressure sensor is applied to measure positive, negative or differential pressure in clean air and gaseous media. It is used in clean-room, medical
and filter technology, ventilation and air-conditioning ducts, spray booths, large-scale catering facilities, for filter monitoring and level measurement
or for triggering frequency converters.
Innovative Modbus sensor with galvanically separated RS485 Modbus interface, selectable bus termination resistance, DIP switch for setting the
bus parameters and bus address in current-free state, LEDs for telegram status display and one a push-in terminal. The sensor is factory-calibrated;
an environmental precision adjustment by an expert is possible.
