Function
The RM-DPS Micro devices from the SensorLine range are electronic differential pressure switches for application in harsh industrial environments. They are used to measure, visualize and monitor non-corrosive gaseous media in above atmospheric and negative pressure ranges. All necessary functions can be easily configured and displayed with the 3-digit display and 2-key menu control. In the operating mode, the display indicates the differential pressure. In addition, the status messages SERVICE / ALARM will be indicated by LEDs. For customer-specific applications, the in-system function can be used to easily add, edit or extend software modules. On request, further sensors are available for special measuring ranges.
Types
The RM-DPS Micro devices are designed for wall mounting in NormLine boxes and are also available for ATEX zone 22, cat. 3D. The explosion proof version is approved by DEKRA-EXAM.
