sy 型湿度遥测警报仪主要是供洞库远距离有线测量库房相对湿度之用,经适当修正亦可应用于各行业仓库、厂房遥测温、湿度。该仪器用半导体热敏电阻作测量探头,经修正校直差值放大,由仪表表头直接读出库房相对湿度(或温度),不需查表计算,使用方便。由于热敏电阻对温度变化反应灵敏,又利用了温差放大原理,经校正可消除线路电阻、线路电阻随外界温度变化以及其它电干扰等的影响。因此该仪器用来遥测相对湿度,具有迅速、准确、测量距离较远等特点。
sy-type humidity telemetry alarm is mainly used for long-distance cable storehouse warehouse relative humidity measurement purposes, the appropriate amendments can also be applied to various industries warehouse, plant telemetry temperature and humidity. The instrument uses a semiconductor thermistor as a measuring probe, amplified by calibrated differential correction, directly read out the relative humidity (or temperature) of the warehouse from the meter header without the need of looking up the table for calculation and easy to use. Due to the sensitivity of the thermistor to temperature changes, but also the use of temperature amplification principle, the correction can eliminate the line resistance, line resistance with the outside world temperature changes and other electrical interference and so on. Therefore, the instrument used to telemetry relative humidity, with rapid, accurate, longer distance and other characteristics.
