Description of a measurement setup for the combined measurement of LLB exposures in dynamic situations using high-resolution measurement technology
- In order to gain an understanding of the Low Level Blast (LLB) exposure of soldiers when using weapon systems, it is necessary to characterize these weapon systems with regard to their overpressure effect [1]. Carrying out static measurements of weapon systems in the rough terrain of firing ranges and training areas poses a challenge for sensitive measurement technology. Furthermore, soldiers are often exposed to LLB in dynamic situations [2]. Therefore, commercially available blast gauges are often used, which, however, are not sufficient for high-resolution measurement of overpressure exposures with academic requirements due to their intended use [3]. Static measurement setups, such as with penile probes, must be used to characterize weapon systems, but they cannot make valid statements about the real load on dynamically behaving soldiers. However, this real load on the soldier is essential in order to be able to adequately assess the potential resulting medical effects.

However, this real load on the soldier is essential in order to be able to adequately assess the potential resulting medical effects.
As part of this challenging measurement task, a prototype of a self-sufficient, high-resolution measurement system is presented, which can be used by an operator in dynamic situations without interference. The complete measuring chain was realized as a self-sufficient unit. The system is based on a 20-liter backpack system, which contains the power supply, the measuring amplifier and the measuring card. The measuring computer is attached to the front of the backpack to allow quick access. The measuring system is capable of recording four channels with a sampling rate of up to 2 MHz. Piezoelectric integrated charge pressure sensors are used as a high-resolution pressure sensor (type: PCB138B32). The pressure sensor is placed on a XX- carrier plates with the dimensions XY × YY. The pressure sensors are attached at the typical positions for Blast-Gauges measurements, like on the left shoulder, on the upper chest and on the back of the head. At the same time, commercial blast gauges are placed at the positions of the pressure sensors to qualify the blast gauges (type: B3 Blast Gauges Gen 6). The measuring system is referred to as a “Sensor Carrier Operator (StEk)”.
As part of the functional testing of the measurement system, tests are carried out with hand weapons. For this purpose, a soldier is equipped with the StEk and blast gauges. The handguns used are the pistole P8 (caliber 9 mm) and the long rifle G36 (caliber 5.56 mm). The firing position is standing freehand. In addition, the soldier carried out an examination of the carrying comfort of the StEk as part of the training. Furthermore, it was evaluated whether the measuring chain was adequately integrated into the measuring system. The quality of the pressure measurement was also examined, whereby a direct comparison was made with the blast gauges.
The measurement system presented here enables the combined (static and dynamic) scientific characterization of weapon systems, particularly with regard to overpressure loading.…
