WIRE SPARK TESTING
InteliSENS® ST-HF Series Spark Tester
Proton Products InteliSENS® ST-HF series high frequency spark testers meet the international standards stipulated for wire insulation testing.
High frequency spark testing allows a greatly increased line speed capability compared with mains frequency testing, especially in the case of UL1581, where the 9-cycle requirement makes the electrode length required for mains frequency testing impractical. Compared with mains frequency testing, high frequency testing generates an ionization cloud at a relatively low voltage. This ensures complete coverage of the wire surface.
Features
- 25mm maximum wire diameter.
- 100mm long bead chain electrode.
- 15kV maximum test voltage.
- Slide bead electrode for easy maintenance.
- Brush electrode version available.
- Distinguishes and separately counts pinhole and bare patch flaws.
- 2.1 to 4.5kHz sine wave test frequency (load dependent).
- 2000 to 3000 m/min line speed (test frequency dependent).
- Ozone extraction port.
- UL1581 compliant spark testing.
Introduction
Proton Products InteliSENS® ST-HF series high frequency spark testers meet the international standards stipulated for wire insulation testing. High frequency spark testing allows a greatly increased line speed capability compared with mains frequency testing, especially in the case of UL1581, where the 9-cycle requirement makes the electrode length required for mains frequency testing impractical. Compared with mains frequency testing, high frequency testing generates an ionization cloud at a relatively low voltage. This ensures complete coverage of the wire surface. The InteliSENS® ST-HF Series gauge head electronics are housed in a rugged IP65 sealed steel case, ensuring reliability and long operational life.Specifications
