Relative pressure transmitter DSI520

thin-filmvoltage outputanalog

Description
The DSI520 pressure transmitter uses thick-film technology. The sensing element is welded to the pressure fitting and requires no seal. The DSI520 converts process pressure values (water, air, etc.) into a standard analog current or voltage signal. It is designed for industrial applications with high safety requirements and is suitable for refrigerants, including ammonia.
