Differential Pressure Transmitters

Suitable for continuous liquids level measurement. SDT is a digital differential pressure transmitter, which has a long term stability and accuracy due to its automatic measure compensation system, related to working temperature modification. SDT can be used for the liquids, gases, and vapors measurement. The SDT series applications are varied: steel, pharmaceutical and food industry. SDT can be ATEX certified. SDT can be applied: for level measurement in tanks with different pressure than atmospheric pressure (eg, carbonated beverages like beer or liquid in the inerting atmosphere); flow measurements in combination with Pitot pipes, Venturi pipes, calibrated flanges or diaphragms. SDT is a solution for many different applications in all industrial process control.
