Weak current College】 【humidity sensor main parameters】.
<br> <br> ⑴ humidity characteristic: means a humidity sensor electric parameter with humidity changes. <br> ⑵ switching characteristics: means a humidity sensor electric parameter in humidity value at which the step property. <br> ⑶ temperature coefficient: also .called humidity temperature coefficient or humidity temperature coefficient, refers to when the ambient temperature changes every 1 ° c, causing components indicates that the amount of humidity changes. <br> ⑷ humidity coefficient: refers to a relative humidity range, relative humidity change l% .RH, humidity sensor electric parameter change values or percentages. <br> ⑸ wet lag: means a humidity sensor l wet and dehumidified, under the same humidity electric parameters of inconsistency. <br> ⑹ wetting hysteresis: means a humidity sensor for ascending dampness .and dehumidified round change of moisture absorption and dehumidification of transmission lines. <br> ⑺ heat lag: refers to a certain humidity, humidity sensor temperature shift from one environment to another environment human temperature electric parameters of hysteresis. <br> ⑻ thermal hysteresis: .refers to a certain humidity, humidity sensor moves from one temperature to another person, the ambient temperature reaches equilibrium electric parameter. <br> ⑼ response time (time constant): refers to a certain temperature, relative humidity occur jump, humidity sensor electric parameter .to steady-state variation of the ratio of the time required. <br> ⑽ resolution: means a humidity sensor detects moisture capacity of the smallest change. <br> ⑾ rated voltage: means a humidity sensor long-term continuous working time allowed to .impose maximum voltage. <br> ⑿ rated current: means a humidity sensor to work towards the continuous length to allow the imposition of maximum current. <br> ⒀ aging characteristics: means a humidity sensor humidity characteristics and time changes. <br> < .br> <br> <br>.
