RX-9929 SMD Temperature Limiter Performance and Life Testing Machine I. Overview According to the standards: GB14536.1, GB14536.10, IEC60730-1 Thermosta. This equipment is used to conduct life tests on single and bipolar contact / automatic and manual reset temperature limiters by simulating the actual working conditions. The testing machine is driven by an air cylinder. Through the movement of the sliding rod, it can lift and lower the test specimens to achieve repeated cycles of heating and cooling. The air source treatment components should include filters, pressure regulating valves, pressure gauges, etc. II. Performance Technical Parameters: l Equipment Power Supply: 250VAC/50Hz, 12KW l Workpiece Temperature Range: Ambient temperature ~ 400℃, with an accuracy of ± (0.3% of the reading + 0.5℃) l Resolution is 0.1℃, and the temperature control accuracy is ±2℃ l Number of Test Stations: 3 stations (optional) III. Life Test: l Test Count: Up to 999,999 times at most. The number of experiments can be preset, and the machine will automatically stop when the preset number of times is reached. l Test Rate: 5 - 10 times per minute (adjustable) l Intelligent Discrimination Function: When the contacts are adhered and there is continuous connection or disconnection, an alarm will be issued when the set number of times is reached. IV. Performance Test: l During the performance test: The requirement for the temperature rise rate is not more than 0.5K/min. l Record the temperature value when the temperature controller operates during the test (with three independent temperature measurement points, and the thermocouple with a diameter of 0.25MM is arranged on the test specimen). l Without test load, with an interface V. Functions of the Testing Software: l Computer display + PLC control l The software is written in VB6.0 on the Win platform, with good human-machine dialogue functions. It can automatically find out the temperature when the test specimen operates, and can display the change curves of temperature and time for each station in real time. It has automatic coordinate changes, and can simultaneously magnify and print various combinations of temperature and time curves, experimental reports, etc. in real time. l All curves and reports are automatically saved to the disk, and all test curves and various data can be queried through the query system. The software has the functions of automatically calculating correction parameters, metering and printing.
