This document is a user manual for differential pressure probes. It mainly introduces the dimensions, installation, connection, placement and use of the probes.
This document serves as a brief guide for the Rotronic RMS-D differential pressure probe, covering main functions, installation, and setup. It includes instructions on connecting the probe to a data logger and positioning it for accurate measurements while avoiding interference from sunlight or heating elements. The manual also details how to integrate the probe into the RMS system via the RMS-LOG software.
