[accompanying drawing explanation]
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model embodiment grain heap humiture detector.
[detailed description of the invention]
Body that the structure of this utility model embodiment grain heap humiture detector as it is shown in figure 1, include is breathed freely,
Sensor circuit, the target seeker 8 of taper and the T-shaped handle being arranged in tube cavity.
Body includes detecting head 1, nylon slider 2, the filter screen 3 of tubular and connecting rod 4.Handle includes hands
The middle part of handle 5, the union joint 6 and RS485 data-interface 7 of tubulose, the upper end of union joint 6 and handle 5 is solid
Fixed connection, RS485 data-interface 7 connects for the cable connector with portable main frame.
Down, threaded with the lower end of detecting head 1 in upper end, the upper end of detecting head 1 at the tip of target seeker 8
