一、前言 响应时间是湿敏元件重要参数之一,评价一种湿敏元件,总是比较关心这种湿敏元件的响应时间。 测定响应时间必须规定湿度变化率及选择合适的湿度源。对陶瓷等电阻式湿敏元件,常规定达到63％湿度变化量所需的时间为响应时间。对电容式高分子湿敏元件,常规定达到湿度变化量的90％时所用的时间为响应时间。至于测定响应时间时所选择的标准湿度源,没有统一规定,通常
First, the foreword Response time is one of the important parameters of the humidity sensor, evaluation of a humidity sensor, always more concerned about the response time of such humidity sensor. Determination of response time must specify the rate of change of humidity and choose the right source of humidity. Resistance of ceramic and other moisture-sensitive components, conventional 63% humidity to reach the amount of time required for the response time. The capacitive polymer humidity sensor, routinely set to reach 90% of the amount of humidity change time used for the response time. As for the measurement of response time selected standard humidity source, there is no uniform regulation, usually
