2 R Air flows from high pressure side to low pressure side. This principle can be applied to keep clean-air in the room or, alternatively, not to leak polluted-air from the room by increasing or decreasing the pressure in the room. The instruments that monitor and control this air flow are called the differential pressure gage. Manostar produced by Yamamoto Electric Works Co.,Ltd, plays an important role in many fields. For example, controling air-condition of the high-rise buildings and the production lines of semi-conductors, monitoring pressure of the clean-rooms and the nuclear facilities. *Refer to p.89 later for some applications of Manostar. In Japan, Manostar has become a synonym of the differential pressure gages. In 1961, Yamamoto Electric Works developed the first Japanese-made differential pressure gage. As the result of continuous improvement and development, we can supply Manostar series" which are the differential pressure gages and switches, and the electronic differential pressure measurement system Manosys". Each product is rated high, because of exceling in cost-effectiveness and providing with broad line-up of accessories since released. Manosys transmits and indicates electric signals converted from the amount of the pressure fluctuatuion. Manosys has been designed to make cost-effectiveness of monitoring and lower energy consumption by the computerized automatic measurement and controling of differential pressure. As demand for miniaturization, high accuracy and application to an advanced network, we will keep evolving with the needs of the age.
