874 type electromagnetic counterDetailed product description：

Working principle and purpose:

The 874 electromagnetic counter is used to record the cumulative number of electrical pulse signals. It can be combined with secondary instruments to form a digital display instrument, widely used for various electrical pulse counting in industries such as petroleum, chemical, textile, machinery, mining, national defense, agriculture, food, printing, etc. After the electrical signal is input into the counter, a suction force is generated in the electromagnet, causing the armature to drive the escapement mechanism and drive the digits to rotate for decimal counting.
