Model 85C17 Ammeter Dial Indicator — Mechanical Amplitude Meter (1 Pc) Clear, reliable visual monitoring of amplitude/current for ultrasonic and welding equipment. The 85C17 is a mechanical dial indicator ammeter designed for integration or replacement in ultrasonic lace machines, mask machines, spot welding machines and similar mechanical systems where visual amplitude or current feedback is required. Key benefits Provides an immediate, easytoread dial indication of amplitude/current so operators can verify correct settings at a glance. Helps prevent equipment damage and reduce scrap by allowing quick detection of outofrange amplitude or current levels. Mechanical, analog operation requires no software and is simple to install and maintain, improving uptime and usability. What it does (functionality) Acts as a dialtype ammeter/amplitude meter that displays the operating amplitude or current level of ultrasonic or welding equipment. Mechanical construction gives a continuous, realtime visual readout without the need for digital interfaces. Suitable for use as a replacement instrument or as an integrated panel meter for process monitoring. Compatibility and applications Compatible with ultrasonic lace machines and mask machines for monitoring ultrasonic amplitude and ensuring consistent bonding/sealing performance. Compatible with spot welding machines to monitor welding amplitude/current for repeatable joint quality. Can be used in other mechanical systems that require a simple, robust amplitude/current dial indicator. Key attributes Model: 85C17. Type: Ammeter / dial indicator / amplitude meter.
