工業用草莓视频色版本分鉑草莓视频色版本和銅草莓视频色版本兩大類。草莓视频色版本是利用物質在溫度變化時自身電阻也隨著發生變化的特性來測量溫度的。草莓视频色版本的受熱部分(感溫元件)是用細金屬絲均勻地雙繞在絕緣材料製成的骨架上。當被測介質中有溫度梯度存在時,所測得的溫度是感溫元件所在範圍內介質層中的平均溫度。裝配式草莓视频色版本主要由接線盒、保護管、接線端子、絕緣套管和感溫元件組成,並配以各種安裝固定裝置。WZP型鉑電阻的感溫元件是一個鉑絲繞組,雙支鉑電阻主要用於需要用二次顯示、記錄或調節儀同時檢測同一地點溫度的場合。WZC型銅電阻的感溫元件是一個銅絲繞組。
草莓视频色版本測溫原理
受熱後的金屬絲電阻隨著溫度的變化而變化,其草莓视频色版本值R(t)與其所處溫度t的關係可表示為: R(t)=Ro(1+At+Bt2+------)按測得的電阻值查相應分度號表即可得出被測溫度值t。或由顯示儀表直接讀出。
Industrial thermal resistance contains two categories, Pt thermal reistance and Copper thermal ressistance.
Thermal resistance is used to measure temperature on the basis of the property that substances’own resistance varies with the temperature. The part of the thermal resistance that is heated (temperataure-sensing element) is made by dual winding of fine wires around the frame made of insulation materials. When there is temperature gradient in the mediums to be measured, the measured temperature is the average temperature in the dielectric layer within the range where the temperature-sensing element is placed.Packaged thermal resistance consists of connection box, protectin tube, connection terminal, insulating sleeve and various fixed devices.WZP Pt resistance’s temperature-sensing element is a Pt wire winding. Double platinum resistance mainly is used fou such situation where it is required to use secondary display instrument, recorder and accommodometer to simultaneously detect the temperature of the same place. WZC copper resistance’s temperature-snesing element is a copper wire winding.
Temperature measurement principle of thermal resistance
The resistance of the metal wire that has been heated varies with the termperature, and the relation between the thermal resistance value and the temperature it is at can be expressed as R(t)=Ro((1+At+Bt2+------)According to the resistance value that is measured to refer to corresponding graduation mark, the temperature t that is measured can be come out, or read it directly from the indicating instrument.
