Crash Test System features miniature design.
August 3, 2012 -
Supplied in 136 x 80 x 40 mm package, M=BUS Pro Fire and Measurement Box, known as FAM Box, can trigger pyrotechnic components as well as inflators for airbags or belt tensioners where firing energy is stored in capacitor. Unit contains 8 isolated channels that can fire independently, and data recorder that logs firing current and voltage signal at sampling frequency of 400 kHz. Crash-resistant up to 1,000 G, FAM Box includes 100 Mbps Ethernet interface and backup system with internal battery.

The FAM Box - The Next Step in Test Equipment Miniaturization
Munich - MESSRING of Munich, the world's leading manufacturer of crash test systems, is the driving force behind technological development in the field of test equipment. Its proprietary M=BUS technology represents the next step in test equipment miniaturization. The latest device in its product lineup is the M=BUS Pro Fire and Measurement Box, also known as the FAM Box.
The FAM Box can trigger pyrotechnic components as well as inflators for airbags or belt tensioners, where the firing energy is stored in a capacitor. This advanced test device for crash testing comes in a small package with compact dimensions and contains a total of eight fully isolated channels that can fire independently.
A high-speed data recorder logs the firing current and voltage signals at a sampling frequency of 400 kHz with 16-bit precision. Its programmable firing current-limiting monitors check the so-called All-Fire and No-Fire criteria to ensure that the connected pyrotechnic system fires reliably when the specified electrical current strength is reached (All-Fire), and that it does not fire at all during a No-Fire condition. This is how MESSRING can guarantee top precision in monitoring the firing process and offer very fast and better evaluation for all test engineers and technicians.
Mounting the FAM Box inside or outside the vehicle is very practical and easy. All that is needed is a mounting rail, upon which all M=BUS components are mounted next to one another. The mounting rail can then be installed in the test vehicle, e.g. in the trunk space. When the supplied bracket is used, the box can be placed in a decentralized mounting location in a test object.
A key criterion for sophisticated on-board test equipment is its protection of measurement data; if this data is lost, the entire test is rendered useless. That is why the FAM Box is equipped with a backup system. An additional safety feature for preventing faulty unit triggering is a safety key, which only releases the firing energy after it is activated. The box can also withstand extreme mechanical stress; it is crash-resistant up to the application of a 1,000 G.
"Our primary focus is on continually optimizing test components so that they attain even greater precision and more reliable test results for our customers," explains Dierk Arp, CEO of MESSRING. The FAM Box is another important step towards making onboard measurement devices more compact, efficient, and safe."
Easy operability is an integral feature of all products from MESSRING; not only can the FAM Box be controlled from a simple Web browser and a PC, it can also be controlled from devices such as an iPad.
