About the DSA3217-PTP | DSA3218-PTP Pressure Scanner

The DSA3200-PTP series pressure scanners are versatile, all-in-one data acquisition systems. Each DSA3217/3218 -PTP is built on a pressure sensor per measurement channel architecture. Every pressure sensor is uniquely calibrated over a wide temperature range. All data acquisition, data conversion and communications tasks are handled by the integrated A/D converters and processor. This combination provides easy setup, simple operation and long term reliability.

In addition to the electronics, internal calibration valves are included to provide maximum functionality. The valves allow for several logic states including measurement, isolate, calibrate and purge. In the calibration configuration, either a known pressure can be applied for a span verification/correction, or the sensors can each be pneumatically shorted together allowing for a quick zero offset calibration. This zero offset calibration feature, in conjunction with the sensor’s natural stability and repeatability combine to provide maximum long term accuracy.
