Name: YK-3054 Hot Wire Tester

[Product Introduction]：

This testing instrument is mainly used for electronic and electrical components or parts that may reach excessively high temperatures or ignite nearby parts under fault or overload conditions. The hot wire test simulates the thermal stress caused by heat sources or ignition sources such as hot elements or overloaded resistors in a short period of time, and evaluates the fire hazard using simulation technology. It is suitable for plastic and non-metallic insulation material parts used in electrical and electronic products, components, and household appliance components, such as switch housings, relay sockets, etc.

[technical parameter]：

Ø Box volume: ≥ 0.5 cubic meters, with glass observation door

Illumination inside the box: less than 20LUX

Ø Control system: PLC+touch screen

Ø Printer: Automatically prints test data

Ø Hot wire temperature: adjustable from room temperature to 1100 ℃

Ø Temperature gauge: intelligent temperature controller with an accuracy of 0.1 ℃

Ø Thermocouple: Imported Ø 1.0mm nickel chromium armored (K-type) imported thermocouple is used

Temperature allowable error: 500~750 ℃± 5 ℃; 750 ~ 960℃±10℃

The force applied by the hot wire to the sample is 1.0 ± 0.2N, and the depth of compression is limited to 7mm ± 0.5mm

Ø Hot wire: Hot wire is a standard size ring made of imported nickel/chromium (80/20) wire with a diameter of 4mm; The diameter of the heating wire before bending is 4.0+/-0.04mm, and it must not decrease to 90% after bending. All other dimensions are made according to the standard error requirements

Ø Moving speed of the hot wire top approaching and leaving the sample: 10mm/s-25mm/s

Ø Timer: Imported timer is used, adjustable within the range of 0~99 minutes and 99 seconds, with an accuracy of ± 0.1 seconds. The burning time (Ta) can be set, and the ignition duration (Ti) and flame extinguishing time (Te) can be recorded

Product features: The control system of this testing instrument is automated. After starting, the small car that holds the sample will automatically move the sample to the hot wire. After reaching the set hot time, it will automatically return. The interior has a black background and is equipped with ventilation and lighting devices. The time and temperature are displayed digitally for easy observation and recording.

Ø Power supply: AC 220V, 50H
