SpectralShieldTM is designed to characterize the physical properties of manufactured products. It can be used to reduce warranty costs by identifying defective products. Use of this system allows products to be graded directly on the production line and to be sold later by quality level. The system also provides the quality metrics documentation requested by many customers (COFA) and can be a key factor in improving the manufacturing practices of any company. In addition to being an essential tool for quality control personnel to monitor the manufacturing process, it can also be utilized to both increase yields and tighten product tolerance.
Most sensors that produce an analog signal can be connected to the SpectralShieldTM system. Flexible signal conditioning provides programmable gain, anti-alias filtering, overload protection, AC/DC coupling, and IEPE transducer power. The system supports a wide range of sensors including accelerometers, displacement sensors, pressure transducers, proximity probes, thermocouples, flow meters, LVDTs, and strain gauges.
An operator can easily configure tests by defining the acceptable time, frequency, and statistical limits for a product. Once configured, the system can detect transient events, such as spikes, glitches, or frequency components that are related to known product failures, such as broken gear teeth or defective bearings. SpectralShieldTM can be configured not only to measure the tested part, but also the test stand and surrounding environment. These additional measurements enable the operator to recognize and take action to modify the external influences that might cause an other-wise good product to fail.
SpectralShieldTM can run as a stand-alone system or with limited operator interaction. The data acquisition can be triggered by an operator, an external relay, an industrial computer, or a process logic controller (PLC). Regardless of how the system is configured, it will acquire and process the incoming signals, compare them against good product signatures, then provide an appropriate Pass/Fail message.
