DANFOSS DST P140 Series Pressure Transmitter | For Booster Pumps and Air Compressors

DANFOSS DST P140 Series is a pressure transmitter designed for industrial and OEM applications, engineered to perform reliably in demanding environments. It is well suited for booster pump systems, pressure-boosting water pumps, and air compressors that require accurate, continuous pressure control.

This series combines MEMS technology with an ARM-based microcontroller to enhance signal stability and enable advanced diagnostics. These diagnostic functions support quicker troubleshooting for operators and maintenance teams, helping reduce downtime and minimizing on-site troubleshooting costs.

The wetted parts are built with a fully welded, hermetically sealed stainless-steel construction, reducing the risk of leakage and making it suitable for water and air systems where protection against contamination and moisture matters. The design is also developed to withstand vibration and mechanical shock commonly found in machine and field applications.
