Diversified Technical Systems, Inc. (DTS) offers the ARS PRO high-performance angular rate sensor, which is designed for a range of applications including vehicle handling, crash, biomechanics, and even high-rate ballistics testing. The single axis ARS PRO is a silicon-based microelectromechanical system (MEMS) that uses a resonating gyro to measure angular velocity. Referred to as “ultra-small and rugged,” its other key advantages include dc response, low power requirements, high output voltage, and shunt check capability. All models are linear over the rated range and comply with SAE and ISO recommended practices for frequency response in all applications. DTS offers full-scale ranges from ±300 to ±50,000°/sec and bandwidths up to 2000 Hz, fully supporting CFC 180 and 1000 testing requirements. The ARS PRO-1500 also is NHTSA-specified for FMVSS 2020a rear impact testing. DTS also offers the ARS HG with a 10,000 g shock rating—the highest in the industry, it claims—which features reinforced mounting points designed to withstand high energy test environments including blast and missile. All models are packaged in compact rugged enclosures and weigh 2.5 g (0.09 oz).
