BL-W100 integrated temperature transmitter measurement side stainless steel shell packages, head for the aluminum waterproof junction box, widely used in thermal engineering, power, food, pharmaceutical, pressure vessel, petrochemical and other process industries as well as Ovens, plastic chemical fiber, machinery and equipment and other large refrigeration units the temperature measurement.
Ⅱ, the working principle
Thermocouple electrodes formed by the two different conductor materials. When the measure-terminal end with the reference temperature difference, they will generate thermoelectric power, the work of a thermoelectric power meter will show the corresponding temperature.
Thermal resistance is the use of material changes in temperature, its resistance also changes with the characteristics to measure the temperature. When the resistance changes, the working instrument to show that the temperature corresponding to the value of resistance.
