Real-Time Quality Monitoring At The Coil

The Sign-LinkŪ Coil Signature Monitor charts the heat pattern of parts as they are processed. The profile generated is compared to the profile of a "master" part stored in memory to provide real-time verification of part quality. Should a problem occur while heating a part, the Sign-Link Monitor alerts the operator so adjustments can be made before a bad part is produced.

A Sign-Link system allows you to monitor power, amperage, voltage, quench temperature, quench flow, and part rotations. Built-in capabilities which enhance the flexibility of the system include a linking feature that allows multiple profiles, such as hardening and tempering, to be evaluated during a single cycle; signature repeat which allows evaluation of the same signature repeatedly in continuous applications, like tube welding and annealing; and dead banding to allow non-critical segments of a heat cycle to be ignored. In static heating applications, the monitor can be programmed to automatically shut down a power supply after the desired energy has been achieved.

Sign-Link Monitors are compatible with solid state power supplies, radio frequency power supplies, and motor generators. Equipment can be interfaced with an optional printer or computer, and includes software to allow data to be downloaded to Lotus or Excel spreadsheets.

Two versions of the Sign-LinkŪ Coil Signature Monitor are offered. The basic unit features an 80 character alphanumeric display. The Sign-LinkŪ Deluxe offers advanced features like touch 15" color touch screen,40 gigabyte hard drive for storage, 1.7 Mhz Intel Processor, networking capabilities,  real-time graphics, and statistical process control (SPC) capability.
