我厂SHL6.5T/13kg锅炉水位显示报警所采用的仪表是苏州娄葑无线电厂制造的DS—7型电接点水位计,它通过取样筒上15个电接点,将取样信号分别送入对应的15个门电路,来进行光带显示。经数年使用,仪表性能尚好,能有效地反映出水位的高低。根据使用说明,取样筒体上的电接点每半年需拆检一次。在拆卸中,我们感到取样筒上的电接点,由于其绝缘套管是由陶瓷制成的,稍受震动即碎,而每只电接点的价格
Our factory SHL6.5T / 13kg boiler water level alarm display instrument is used by Lou Lou radio factory in Suzhou DS-7-type electric contact water level meter, which through the sampling tube on the 15 electrical contacts, the sampling signal into the corresponding 15 gate circuits for light band display. After several years of use, the instrument performance is still good, can effectively reflect the level of the water level. According to the instructions for use, the sampling cylinder on the electrical contact to be dismantled once every six months. During disassembly, we felt that the electrical contacts on the sampling cartridge were vibrated slightly because of their insulating sleeve made of ceramic, and the price of each electrical contact
