Product performance:
Dial of the hour meter is silk screen printed. The internal transmission gear of the movement is made of wear-resistant POM plastic, which has good shock resistance and temperature resistance. The shell is made of ordinary ABS or flame-retardant ABS plastic, and the temperature can reach 85°C; the base is made of PC or flame-retardant PC plastic, and the temperature resistance can reach 120°C; the withstand voltage is higher than 2000V. The installation adopts high-strength material clamping parts to be installed by screwing nuts, which is simple and firm.
Measurement characteristics:
The cumulative timetable is composed of a microprocessor, a transmission gear and a counter head. When the power is on, the microprocessor outputs a standard pulse signal to drive the magnetic induction gear and transmits it to the counter to superimpose the accumulated time, so as to achieve the purpose of timing. The cumulative timetable is mainly used to provide scientific basis for the accumulative actual working time of various machinery and equipment to collect Kunqu opera and to track and monitor the assessment and maintenance cycle of precision instruments and equipment. It has high precision, stable and reliable performance, long life, and wide adaptability to the environment, but its frequency adaptability is poor.
