Industrial Pressure Transducer

Proportion-Air manufactures the DSB industrial pressure transducer. The DSB is the standard transducer offered in our DS-Series. Originally “DS” meant “Down Stream” to indicate a pressure transducer that is used to provide electronic feedback from the output pressure of a volume booster back to a QB2 series dual-loop proportional control valve. The DSB is most often used this way, but it makes a great standalone transducer as well.

The DSB industrial pressure transducer accurately measures the pressure of non-corrosive gases with an electrical output signal that is proportional to the full calibrated range. For example, a 0-100 PSI calibration with a 0-10 VDC output would read 5 VDC at 50 PSI.

This industrial transducer can be used as standalone transducer or as 2nd loop feedback in a Proportion-Air 2-loop pressure control assembly. Give us a call–we are happy to help identify the best solution for your application.

DSB | Industrial Pressure Transducer

The DSB is a compact and lightweight electronic pressure sensor with the ability to measure from full vacuum to 175 PSI. This transducer can be calibrated to any range in between and as low as 0-2 inches of water column for a full scale accuracy of ±0.2%. The DSB can be configured with flying leads to connect to any PLC analog card, or with a 3-pin connector to mate easily with a Proportion-Air electronic pilot (QB2X or QB2S) to improve accuracy, repeatability and eliminate hysteresis when controlling pressure with a 2-loop volume booster assembly.
