Position selection of humidity meter in wood drying kiln
Moisture meter in wood drying kiln location must be able to truly reflect the actual status of indoor air medium (temperature, humidity), which can reflect the average status of indoor air, generally choose the material pile side into the wind and the position of representative.If dry indoor air circulation is reversible, the pile wood moisture meter shall be installed on both sides, so that any time can stack into the wind with the village side of temperature and humidity as the basis of executing drying.
If using glass tube liquid thermometer hygrometer, hygrometer window high position should guarantee the operator head-up observation shall prevail;If the thermal resistance thermometer or thermocouple thermometer hygrometer, should be separately installed on both sides of material heap two identical hygrometer, height direction in high l / 2, position, in the middle of a drying chamber length direction.Two hygrometer can be switch rotation measurement, make the hygrometer on one side of the wood pile into work, to measure material pile of one side of the air inlets, medium state (temperature, humidity).
Due to the drying chamber has laid the captain axis, short axis wind machine, lateral ventilation type, side wind machine, hot air type and a variety of types such as jet type, and each type of drying chamber fan, heater installation also varied, therefore, the moisture meter location choice also can’t be the same, each enterprise according to the characteristics of their respective drying chamber structure, based on the above basic principles, carries on the reasonable choice.
