Versatile and Customizable Mobile Measurement System - The Mobile Measurement Node

RET4000 is part of Parametric’s time-synchronized, mobile RET measurement system, designed to record analog and digital values from external sensors. Its rugged, IP67-rated, high vibration-resistant design is built for demanding industrial and railway applications.

The modular architecture allows expansion with additional functions, offering a versatile, future-proof solution for data acquisition and real-time monitoring - specialized standard sets support rail monitoring, brake analysis, and operational data tracking, ensuring higher safety, reliability, and efficiency.

Also for Infrastructure Measurements

Besides mobile use on the vehicle, RET4000 is also recommended for infrastructure measurements - installed directly on the track or at switches. This allows mechanical loads, vibrations and other measured variables to be captured directly at the infrastructure, time-synchronized with other RET measuring devices.
