NEW MSR175Pro: Transport Shock Monitoring Data Logger for Heavy-Load and Transformer Shipments 

3-axis acceleration sensor with selectable measuring ranges ±10 g, ±20 g or ±40 g · signal filtering · temperature, humidity, air pressure and light sensors · memory capacity: 2 million measurement values

The MSR175Pro is designed for monitoring mechanical shock and impact loads in demanding transformer and heavy-duty transport applications. The robust data logger provides objective, traceable measurement data for evaluation of transport related stresses and for the factual assessment in case of damage.

Based on the proven technology of the MSR175 series, the MSR175Pro has been specifically developed for transport applications involving high masses and short-duration, highly dynamic shock events. The integrated 3-axis acceleration sensor with selectable measuring ranges of ±10 g , ±20 g, and ±40 g reliably records both low-frequency transport loads and short-duration shock events. Selectable sampling rates from 4 Hz to 4000 Hz, combined with anti-aliasing, decimation and high-pass filters, enable clean separation of relevant shock signal components from static acceleration influences. This allows transport-induced loads to be technically assessed correctly and misinterpretations caused by gravitational acceleration or vehicle motion to be avoided.

Tamper-proof event recording and reliable data

The event-based data storage with shock thresholds selectable in defined increments from 0.5 g and a separate auxiliary memory that can not be overwritten ensures that critical transport loads are recorded completely and tamper-proof. The recorded time histories and directional information allow precise reconstruction of the load situation and provide a reliable data basis for damage analysis, acceptance procedures and the technical clarification of liability and insurance matters.

Software package included in delivery

The MSR175 software package supports all data loggers of the MSR175 product family, including the MSR175Pro, and is used for configuration, evaluation and documentation of the recorded measurement data. It enables efficient processing of large data volumes and traceable analysis of transport-relevant events.

Three powerful software tools are included:

• MSR Dashboard for straightforward configuration of the data loggers, management of multiple devices and rapid data readout via USB
• MSR ReportGenerator for automatic creation of transport-relevant reports
• MSR ShockViewer for detailed analysis, visualisation and evaluation of shock profiles and dynamic events

FAQ – frequently asked questions about MSR data loggers

Monitoring mechanical loads during the transport of power transformers

During the transport of power and large-scale transformers, mechanical loads represent a key risk to operational reliability. Due to their size and mass, transformers are often transported in partial assemblies and only finally assembled at the installation site, resulting in multiple handling and transport stages.

Throughout these processes, the cargo is exposed to shocks, vibrations, tilting and short-duration impact events, which may cause damage that is not visible from the outside. Windings, core structures and insulation systems are particularly sensitive, as even minor displacements or material damage can impair electrical integrity.

The MSR175Pro shock data logger enables continuous monitoring of these mechanical loads throughout the entire transport process. Critical shock events and threshold exceedances are reliably recorded and documented. The measured data provide an objective basis for assessing the transport condition upon arrival at the destination. This allows potential transport damage to be identified at an early stage, responsibilities to be clarified, and risks for subsequent commissioning to be significantly reduced.

The MSR175Pro transport data logger, manufactured with Swiss precision engineering, enables accurate recording of critical events and thereby contributes to sustainable cost reduction.
