YDS2 double needle electrical measuring instrument

YDS2 type double needle locomotive instrument is a fixed type of electric measuring instrument directly acting on the analog display, installed in the locomotive cab control table, including DC ammeter, tachometer, temperature meter, etc., used to measure the current, voltage, speed, speed, temperature, pressure and other operating parameters of the locomotive electric engine diesel engine system. The instrument has the advantages of high accuracy, good linearity, small size, light weight and stable operation, which is suitable for the running condition of railway locomotive. The instrument belongs to the magnetoelectric system structure, the shell is made of plastic 11-10 bakelite pressing, the surface shape is small and has good electrical and mechanical strength. The magnetic material is made of high coercive magnetic steel, with large magnetic energy product and stable performance. The measuring mechanism has a shock absorber and convenient disassembly, the instrument adopts a diode combination power supply board, has an anti-reverse circuit protection device, and has the characteristics of soft light, low temperature and long life.
