Glow Wire Apparatus HD***1 Product explanation: This apparatus is designed to perform tests specified in many standards to check Resistance to Fire in Insulating parts. The testing of electro-technical products for fire hazard is conducted by simulating as closely as possible actual effects occurring in practice. Parts of electro-technical equipment which may be exposed to thermal stress due to electric effects & deterioration of which may impair safety of equipment shall not be unduly affected by heat & fire generated within the equipment. Features: * Meets requirements of the latest IEC specifications as per IEC *********0. * Precision fine wire Cr, Al, insulated junction thermocouple, 0.5 mm diameter, to measure Glow-Wire temperature. * Controlled by PLC and operating by touch-screen. * Motorized specimen carriage preloaded with force of 1.0 N when in contact with Glow-Wire, and carriage is drove by stepper motor. * Mechanical stopper limits movement of tip of Glow-Wire in to the specimen to 7 mm. * Universal, adjustable stainless steel perforated tray mounting bracket to fix test specimens. Technical parameter: Power source: AC **0V *0Hz. Heating Element: Nickel, Chromium Glow-Wire (*0:*0), 4 mm diameter, shaped as specified in standard. Temperature Sensor: Sheathed Cr, Al thermocouple, 0.5 mm diameter, located in tight fitting pocket hole in glow-wire (Made In USA). Temperature Range: Ambient to ***0C adjustable. Temperature Precision: **5C. Max Output Power: ***0W. TA= Glow wire application time, range = 0.1~ **9.9 s (Factory set to *0 s), you can set the range by touch-screen, and the timer’s precision is **0.1s. TI= Time when specimen STARTS burning, controlled by touch-screen, and the timer’s precision is **0.1s. TE= Time when specimen STOPS burning, controlled by touch-screen, and the timer’s precision is **0.1s. Sample Loading: Test sample contact force against glow wire preloaded to 1.0**0.2N. Penetration depth: 7 mm.
