                                                      Application
                                                      It is usually connected with display meter, recording meter and computer, etc. to directly measure temperature of liquid, vapor, gas and solid surface ranging from -200℃ to 500℃ during various production process.

                                                      Feature

                                                      Spring thermal sensor with good shock-proof performance
                                                      No compensational wire, spare cost.
                                                      High measuring accuracy
                                                      High mechanical strength, good pressure-resistant performance
                                                      imported film resistor with stable & reliable performance

                                                      Operation theory

                                                      It is based on that temperature change of material results in charge of its resistance.
                                                      When resistance value change, the working instrument will display relevant temperature.
