Раскаленной проволокой тестер

Glow-wire tester is designed according to the requirements of IEC60695-2006, Conforms to the new national glow-wire standards which its implement in 2007.9.1.Technical parameters1. Power supply is AC220v ±10% 50Hz2. The temperature of incandescent wire could range from 500°C to 1000°C, with a temperature tolerance for error of ±10°C between 500°Cand 750°C, and ±15°C between 750 and 1000°C. The accuracy of temperature measurement instrument is± 0.5 class.3. The thermocouple for measuring the temperature is armored with the nickel-chromium (K) wire of 0.5-0.55mm.4. The glow-wire imposed on the samples the power of 0.8N to 1.2N, and the restrict indentation depth is at least 7 mm±0.5mm.5. The time of activation (Ta) on the specimen by the incandescent wire ranges from 0 to 99 minutes and 99 seconds. Normally, according to the standard requirements, set the time to 30 seconds, and a timer will be employed to count the time of ignition(Ti) and the time of extinguishments, with the time error of ±1S.6. The control panel increased manually timing buttons. The operation of the equipment is simple, the temperature measurement systemis reliable.7. Can test the Measuring the flame height, accuracy is 1mm., Trolley mobile speed ≥ 10 mmIncrease the function of glow- Wire head has no impact on the structural design.Dolly speed is 10-25 mm / sThe height of the flame can be measured, the accuracyis 1 mm.Test sample fixture isoptional
