由中国建筑科学研究院空调所和浙江东阳节能仪表厂联合研制的CYM-10型风速开关最近通过鉴定。这是一种膜盒式压差仪表,用于有电加热器的空调系统风机的断电保护、空气过滤系统过滤器阻力达到规定值时的压差报警等场合。该仪表采用了不同于国外产品的独特的硅橡胶配方,锒有金属托架带波纹的膜盒,设置了线性良好的力位移放大器,较好地解决了灵敏度及可靠性问题,并可显示
The CYM-10 wind speed switch jointly developed by the Air Conditioning Institute of the Chinese Academy of Building Research and the Zhejiang Dongyang Energy Meter Factory has recently passed authentication. This is a diaphragm type differential pressure meter, which is used for power-off protection of an air-conditioner fan with an electric heater, and a pressure difference alarm when the filter resistance of the air filter system reaches a specified value. This instrument adopts a unique silicone rubber formula that is different from foreign products. It has a metal tray with corrugated bellows and a linear force displacement amplifier. It solves the problems of sensitivity and reliability, and can display
