              Wzpk-231 armored thermocouple





              Product Name: wzpk-231 armored thermocouple




              Product No.: 155511-530
              Product model: wzpk-231
              Updated on: June 29, 2009
              Manufacturer: thermocouple, thermal resistance, bimetal thermometer, polytetrafluoroethylene, PTFE gasket -- Shanghai Feilong instrument and Electrical Co., Ltd
              Customer: can be customized according to the needs of customers


              Characteristics of wzpk-231 armored thermal resistance
              ·The thermal response time is less and the dynamic error is reduced;
              ·Small diameter and unlimited length;
              ·High measurement accuracy;
              ·Imported thin film resistor element, reliable and stable performance;
              Working principle of wzpk-231 armored thermistor
              The armored thermal resistance measures the temperature with the characteristics that the resistance of the material changes with the change of temperature. When the resistance value changes, the working instrument will display the temperature value corresponding to the resistance value.
