Each DSA rack-mount enclosure accepts up to 8 DSA3016 pressure scanning modules. Each module is hot-swappable, requiring no system shutdown to change pressure ranges and incorporates 16 temperature-compensated pressure sensors for a total of 128 pressure channels. Scan rate is 625 samples per channel per second.

The advantages of this system are the temperature compensation, its low data latency, and quick startup times.
Communications interfaces are Ethernet or Serial RS-232.

The DSA4000 comes furnished with a micro SD card which can be used for data storage and is easily removeable.
