Technical Field

The invention relates to the technical field of sensors, in particular to a bulk curing barn dry-wet bulb temperature sensor.

Background

The technical standard of dry and wet bulb temperature sensors of bulk curing barn is specified in the technical specification (trial) revision of bulk curing barn (national tobacco institute of technology, 2009, 418), and the sensors comprise 4 DS18B20 temperature sensors, which are respectively used for measuring the upper shed dry bulb temperature, the upper shed wet bulb temperature, the lower shed dry bulb temperature and the lower shed wet bulb temperature, and 5569-6P plugs are adopted and the pin sequence is specified. The wet-dry bulb temperature sensor comprises 4 temperature sensors, a kettle, a water absorption cotton sliver, a sensor fixing frame and the like. The temperature sensor is cylindrical, the absorbent cotton sliver is cylindrical, one end of the absorbent cotton sliver is placed in the kettle, the wet state of the cotton sliver is kept, the wet bulb temperature sensor is inserted into the other end of the absorbent cotton sliver, so that the surface of the wet bulb temperature sensor is also in the wet state, and the measured temperature is the wet bulb temperature. Because improper use or maintenance can cause wet bulb measurement errors, the tobacco leaf baking quality is reduced. Before baking each time, whether the absorbent cotton sliver is tightly attached to the sensor or not needs to be checked, and if the absorbent cotton sliver is not tightly attached, a measurement temperature error is caused; on the other hand, the absorbent tampon may gradually age after being used several times, the water absorption performance may be deteriorated, the surface of the wet bulb sensor may not be sufficiently wetted, and a measurement error may be caused. But it is difficult to check whether the absorbent cotton sliver and the sensor are closely attached by completely depending on the manual work, and the sensor is easy to forget, and on the other hand, because the absorbent cotton sliver is high in aging speed, the replacement time is not unified, and the randomness is high, the situation of the wet bulb temperature measurement error caused by insufficient water absorption of the absorbent cotton sliver is caused to frequently occur. Therefore, there is a need for improved dry and wet bulb temperature sensors.
