Based on more than 30 years of experience, the Signalysis Steering Column Test System delivers100% inspection confidence to your manufacturing floor. This production test system replaces subjective tests with advanced vibration, sound, motor current and travel velocity algorithms and metrics.

IQC MATERIAL HANDLING controls the part in place and provides the required vibration isolation from the manufacturing facility.

IQC AUTOMATION controls steering column operation through a defined list of functional tests.

IQC MEASUREMENT SYSTEM acquires dynamic response data from a defined set of transducers, sampling rates, digital filters, and sample sizes.

IQC ANALYSIS ENGINE IQC Analysis Engine employs high-level post-processing in time and frequency domains to detect faults in mechanical or moving parts.
