Sensor makes durability, life-cycle & biomechanics testing easier

Life-cycle product testing is easy and portable with embedded DAS and a tiny sensor. The sensor is especially suitable for testing products like sports helmets or hockey sticks that have tight space constraints, all without affecting the test dynamics.

Unlike an accelerometer that measures linear motion, the ARS3 PRO can be used to quantify virtually any object’s position in space, which starts with angular rate measurement. The sensor makes it easy to accurately measure high rates of angular velocity, even in excessive shock and vibration environments. Rugged and ultra-small, three angular rate sensors are packaged in a sealed enclosure capable of withstanding impacts up to 10000G.

The triax gyroscope measures just 19x19x12.5mm and weighs only 9g. For applications requiring three independent sensors to measure pitch, roll and yaw, this design eliminates the need for a mounting block that consumes additional space and adds weight. The result is a self-contained triaxial package that costs 25% less, is 50% smaller and 40% lighter than three DTS ARS PROs combined in a mounting block.

The sensor is available with range options of ±300, 1500, 8000, 18,000, 50,000deg/sec, a variety of bandwidths, DC response, up to 10,000G shock rating, and shunt check capabilities. The ARS3 PRO is suitable for high energy applications such as vehicle crash safety, in-dummy testing, human impact studies, and aerospace and ballistics measurements. It also meets the latest U.S. government dynamic performance requirements.

“The ARS3 PRO is an evolution of DTS innovation in meeting customer needs,” adds Hans Hellsund, Director, Sales & Marketing, DTS. “It has all the inherent reliability and proven performance of the DTS single axis predecessor with shock and vibration tolerances in super high-rate ranges, repackaged into a tiny triax that won’t alter test dynamics.”
