NIVELCO NIPRESS DD-6 Seies User Manual

Thank you for choosing NIVELCO instrument.
We are convinced that you will be satisfied with our product!
1. INTRODUCTION
The NIPRESS DD series differential pressure transmitters measure pressure and convert it into voltage or current. DD-600
family uses piezoresistive silicon sensor, has various measuring ranges up to 1000 mbar. Wall mounted design, suitable for
measuring dry, non-aggressive gases and compressed air. This device is short circuit protected against inverse polarity as
well.
The NIPRESS DD-600 can be used for a wide range of different HVAC applications. Its robust design can be used in
laboratories or under industrial conditions. Preferred areas of use are heating, ventilation and air conditioning systems, clean
room and medical technology, filtering technology and draft metering checks.
