Andreas Mathes

Automotive Sensors and Telemetry Specialist

Andreas is a Technical Sales Manager specialising in automotive sensors and wireless telemetry systems. He understands the significance of reliable transmission and high availability of measurement data in test driving, which can be both expensive and time-consuming. In particular, when capturing data on various vehicle components during test track activities such as measuring vehicle dynamics, RLDA, braking, or conducting off-road tests in challenging conditions like water, snow, or mud, the selection of a dependable and accurate sensor, specifically a wheel force transducer, becomes crucial. With his extensive 25-year background in automotive measurement, driving dynamics, rail applications, and telemetry customer solutions, he has actively contributed to product development. Through his expertise in providing customer advice, delivering service support, implementing telemetry applications, and offering on-site assistance at test tracks and lectures, he possesses a deep understanding of Axiometrix customers' requirements and can effectively assist them in their project implementation.
