Thermocouples are a widely used type of temperature sensorfor measurement and control,and can also convert a temperature gradient into electricity.
When two wires composed of dissimilar metals are joined at both ends and one of the ends is heated, there is a continuous current which flows in the thermoelectric circuit. If this circuit is broken at the center, the net open circuit voltage (the Seebeck voltage) is a function of the junction temperature and the composition of the two metals. Which means that when the junction of the two metals is heated, or cooled, a voltage is produced that can be correlated back to the temperature.

J; K; S Type Thermocouple. The J-type thermocouple is the most commonly used, inexpensive electrical device that can measure temperatures from -200°to 1250°C(-328°F to+2282°F).
This type of thermocouple is magnetic, typically made of nickel, with a property to change its output when the material reaches its Curie point at around 365°F.
How does a thermocouple work?
A Probe temperature sensor is a temperature-measuring device consisting of two dissimilar conductors that contact each other at one or more spots. It produces a voltage when the temperature of one of the spots differs from the reference temperature at other parts of the circuit. Thermocouples are a widely used type of temperature sensorfor measurement and control,and can also convert a temperature gradient into electricity.
Commercial thermocouples are inexpensive,interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation.
Professional selection,stable performance and more accurate,suitable for chemical industry, aquaculture ,food ,packing ,medical electronis and other industried with temperature control equipment.

Air shaft is a special shaft for winding and unwinding. The shaft is created by the key on the surface, which will be expand when the high-pressure gas filled in the shaft. Air shaft is easy to operate, the user only have the air supply with the air pressure controlled within 6-8kg/cm2. Just aired the shaft through the air valve and when user want to lock the web. Just push the core activities of the air valve to deflate, the keys will revert to its original appearance, then web can be removed easily.
