MSR Electronics has upgraded its MSR 165 data logger to extend its working range from 15g up to 200 g and enable a recording period that is up to ten times longer. MSR launched the mini logger five years ago. Features are 1600 shock measurements per second in all three axes, the capacity to store over 1 billion measured values and the option of equipping the unit with additional temperature, humidity, pressure or light sensors. All this is diligently manufactured in Switzerland and packaged in a compact case.
The extended working range is beneficial when it comes to recording applications where very large forces occur suddenly, for instance in the field of transportation monitoring of delicate goods, aerospace, as well as drop and impact tests in the industry. The 3-axis acceleration sensor starts recording data either when an acceleration threshold is exceeded or at a set time. 32 measured values are recorded even before the shock event takes place, in order to ensure that the history of the shock can be examined during a g- analysis. As a result, the user not only knows that a shock has occurred but also identifies the exact development of the shock.
The data logger works self-sufficiently in long-term operation, and it has extremely low power requirements due to its high-performance 3-axis digital accelerometer (150 microampere, 13-bit resolution). A rechargeable 800 mAh lithium-polymer battery, enables the unit to record shock measurements over a period of up to six months by default. In order to satisfy the demand for an even longer recording period, MSR Electronics now offers two additional options for long-term power supply to the data logger.
For a longer recording period of up to five years – which is, for instance, required in order to document transportation, storage conditions and operating conditions of machines to be exported over a long period of time – the MSR165 can now be equipped with replaceable batteries (3.6 V, 2 x 7700 mAh, Li-SOCl2). The batteries are stored in an industrial-strength, splashproof cast aluminium case.
Another option of increasing the recording period of the MSR165 by up to six times is to use the “MSR Power Pack”. This is an autonomous charging station with a capacity of 5000 mAh that can be used to recharge the internal battery of the data logger during operation. The charging interval of the unit can be adjusted individually: 24 hours, 7 days or 30 days.
