The microprocessor controlled DS01+ pressure transmitter is used for measurement of differential, positive and negative pressure variations of non-aggressive gasses.
The application utilizes a piezoresistive silicon sensor.
Depending on the type of DS01+, pressure ranges from 2.5 mbar to 100 mbar can be measured. The pressure transmitter is available in two basic versions.
By using a DIP switch four different pressure ranges can be set.
The DS01+ offers maximum flexibility not only in terms of pressure ranges but also the output signal and time constant can quickly and easily be adjusted.
Due to its light-weighted and compact construction it is ideal when measurement of low ranges in confined space conditions is needed.
The wear-free measuring system allows an almost maintenance-free operation.
Zero-point and amplitude can easily be adjusted if necessary.
