Stone crushing machines have been fitted with rugged SomatXR DAQ systems for measuring stress in extremely harsh environments.

When Terex Pegson MPS needed a reliable and flexible system to measure stress on its LJ5139 stone crushing machine, it turned to HBM to provide a comprehensive and effective method.

Following a thorough study of the issues faced by Terex Pegson MPS, HBM specified its rugged DAQ, SomatXR series, which is particularly suitable for use in harsh environments. To compliment this package, HBM also suggested the Somat MX1615B-R module and related accessories, which included RF-9 strain gauge rosettes.

Given the demanding environment, it was important that Terex Pegson MPS specified the correct equipment. “Often faced with wet and arduous conditions, the ability to operate reliably under harsh conditions and sudden impacts was a key consideration for the customer when it came to suggesting the SomatXR system” explains Gregg Todd, HBM Mobile Data Acquisition Specialist.

The powerful SomatXR data acquisition system is specifically developed for use in harsh environments. The modules provide a wide temperature range and are protected from humidity, dust, shock and vibration.

The data acquisition system provides a web interface for simple operation without any software installation. This allows for convenient channel parameterisation, monitoring of measurement jobs and visualisation of measured data far away from the measuring point. This was a particularly significant feature for Terex MPS, given the nature of the measurement task.

Another factor which was taken into consideration when specifying the Somat XR series was the operating conditions. For instance, when operating under such extreme conditions, it’s often hard to anticipate all of the problems that may occur, such as losing measurement data due to unforeseen events, such as a power failure. The SomatXR system enables data to be continuously recorded. This means that should a failure interrupt a test, recorded data up until that point will be saved. This was a particularly relevant feature in terms of the long term tests, typically performed by Terex MPS.

HBM data acquisition systems are suitable for a wide range of mobile testing applications. Despite the immense load requirements and extreme environmental conditions, HBM was able to provide Terex MPS with a reliable and flexible system.

In addition to specifying and supplying Terex MPS with a system to meet its needs, HBM also provided engineers with valuable training and continued support, where needed.
