德国灼热丝测试仪

德国Wazau型号GPG灼热丝测试仪，DIN EN 60695-2-10灼热丝测试

应用领域：主要用于模拟灼热元件或过载电阻之类的热源或点为源在短时间所造成的热应力，适用于电工电子产品，家用电器及其材料进行着为试验，也用于无火焰引燃源着火试验，以测定相关材料的灼热丝起燃温度和可燃性，耐燃指数。

Glow-Wire Tester Type GPG accord. to DIN EN 60695-2-10 and IEC 695-2-1

Application - Fire hazard testing

Principle - The tester serves to investigate the fire-resistant properties of materials and end products. The glow-wire itself is the source of fire. The temperature of the glow-wire is set and controlled by a temperature controller. During a test the temperature controller can be operated in a manual mode to generate a defined voltage signal on the manipulated variable （glow-wire）, thus avoiding a feedback of the reference variable （thermocouple） on the temperature controller. The temperature of the glow-wire can be set from room temperature to 1000℃. The temperature of the glow-wire is detected by a sheathed thermocouple type K （class 1） in accordance with IEC 60584-2.

During the test the specimen is moved at a constant velocity of 11 mm/sec toward the glow-wire and back. The heating time of 30 sec is quartz controlled. The specimen support is pulled toward the glow-wire with a force of 1 N. The power supply is 230 VAC
