RS100热式质量流量传感计是通过测量电阻变化计算测量气体的质量流量。传感器采用质量流量芯片，具有直观、精准、稳定、耐高低温、线性好、响应时间快等特点The Retz thermal mass flow sensor calculates the mass flow rate of a gas by measuring changes in resistance. The sensor adopts a mass flow chip, which is intuitive, accurate, stable, resistant to high and low temperatures, has good linearity, and fast response time
应用行业
应用于监测空气、氮气、氩气、二氧化碳、氧气等干燥洁净无腐蚀性气体（易燃易爆 炸气体除外）的质量流量，可广泛应用于高校科研、消防、环境监测、烟草、智慧农业、食品、医药等行业Applied to monitor the mass flow rate of dry, clean, and non corrosive gases (excluding flammable and explosive gases) such as air, nitrogen, argon, carbon dioxide, and oxygen, it can be widely used in industries such as university research, fire protection, environmental monitoring, tobacco, smart agriculture, food, and medicine
