Temperature Sensor Detects Defrost Wires [Success Story]
Affordable solution—the T-GAGE enables cost-effective testing of each defrost wire without requiring complicated maintenance
Improved quality control—by leveraging the sensors’ output data, the supplier can verify that window components have been fully tested and avoid noncompliance penalties
In the tier one automotive world, component testing is key. A single defective part in a production order and the manufacturer may scrap the entire shipment, placing potential re-testing and shipment costs on the supplier.
An automotive manufacturer was rejecting a supplier’s shipment of rear window assemblies due to faulty defroster grids. The supplier’s existing test procedure measured current draw across the entire heating system to detect an overall failure, but it could not detect the subtle impact of a single heating wire being broken. The window supplier partnered with a Michigan-based machine automation company to create a better test fixture—one that can verify each defrost wire heats to specification prior to shipping.
Before Banner recommended the T-GAGE, the Michigan OEM was considering using infrared imaging technology. Infrared testing is complex, costly and requires end users to learn proprietary software and have PCs readily available. With the cost effective, self-contained and easy-to-use T-GAGE, the OEM was able to assign one temperature sensor per defrost wire for a comprehensive test fixture and procedure, enabling the supplier to produce a more reliable product.
