Welcome friend~ QDL80A temperature sensor No display type Default thread size M20*1.5 ( if you need other thread size,G1/2 ,G1/4,G1/8,1/4NPT,M10*1 pls contact us,tks) Default probe diameter: 6mm Material: SS304 power supply : DC24V Note: other temperature rangeoutput signalthread sizeprobe lengh pls contact us for a customization,TKS Description: This PT100 temperature transmitter adopts thermocouple or resistance as the temperature measuring element it is normally matched with display,recording and regulating instrument to measure the temperature (from -50 to 250 Centigrade)of liquid,steam,gas and solid during various production process. The thermocouple (resistance) measure the changes of thermal power (resistance) when working,which will produce unbalance signal through the temperature transducer's bridge,and the signal will be amplified and converted into 4-20mA DC signal to the instrument,then the instrument will display the corresponding temperature value. It can be widely used in automation temperature control system,such as metallurgy,machinery,petroleum,electricity chemical industry,light industry,textile,building materials and so on. _x000D_
