【発明が解決しようとする課題】プリント基板の測定回
路には外部から電源が供給されるため発熱し、筐体は熱
容量をもっているため筐体内部の温度は安定せず、温度
測定、湿度測定が正確となるまでの安定時間が長くな
り、また、動作状態が変わると消費電力が変わり、筐体
内部温度も変化し、温度が落ち着くまでに時間を要し、
測定中も不安定となりやすかった。The measurement circuit of the printed circuit board generates heat because power is supplied from the outside, and since the housing has a heat capacity, the temperature inside the housing is not stabilized. The stabilization time until it becomes accurate becomes longer, the power consumption changes when the operating state changes, the temperature inside the housing also changes, and it takes time for the temperature to settle down,
It was easy to become unstable during the measurement.
【０００４】この発明は、以上の点に鑑み、高応答、高
安定性が実現できる検知装置を提供することである。SUMMARY OF THE INVENTION [0004] In view of the above, an object of the present invention is to provide a detection device capable of realizing high response and high stability.

外部に延出されるようになっている。In FIG. 1, reference numeral 1 denotes a wall surface, on which a resin housing 2 is attached with its foot 2a. A measurement circuit board (printed circuit board) 3 on which a circuit element 3a is mounted is provided in the resin housing 2 and attached to the resin housing 2. It has been extended to the outside.

金属板６が設けられている。A sensing element 4 such as a temperature sensor or a humidity sensor is provided on the measurement circuit board 3 with its base fixed and protruding from the surface 2b of the resin housing 2 to the outside. A metal cover 5 having upper and lower openings 5a and 5b covers the sensing element 4 and is provided on the surface 2b of the resin housing 2. Further, a metal plate 6 is provided on a surface portion 2 b of the resin housing 2.

a, the air A passing through the upper and lower openings 5a, 5b is easily adapted to the temperature of the metal cover 5, and is covered by the metal plate 6 from the resin housing 2. Heat radiation can be avoided, and the space with the metal plate 6 has a uniform temperature due to the cavity radiation effect,
Fast and stable heat balance can be realized.
