The platinum-rhodium thermocouple is also an important type of thermocouple. Then, in the actual use of the platinum-rhenium thermocouple, does everyone summarize the advantages of the platinum-rhenium thermocouple? In fact, there are different advantages in different fields.
Platinum rhodium thermocouple, also known as high temperature precious metal thermocouple, platinum rhodium platinum platinum rhodium (Platinum rhodium 10-platinum rhodium) and double platinum rhodium (Platinum rhodium 30-platinum rhodium 6) points, they as a temperature measurement sensor, usually with the temperature Transmitters, regulators, and display instruments are used together to form a process control system for direct measurement or control of fluid, vapor, and gaseous media and solid surface temperatures in the 0-1800°C range of various manufacturing processes.
The platinum-rhodium thermocouple has the advantages of highest accuracy, best stability, wide temperature measurement temperature range, long service life, and high temperature measurement upper limit in the thermocouple series.
Suitable for use in oxidizing and inert atmospheres, but also for short-term use in vacuum, but not for use in reducing atmospheres or in metal or non-metal vapor atmospheres.
A distinct advantage of the B thermocouple is that it does not require compensating conductors for compensation because the thermopower is less than 3 μV in the 0 to 50°C range.
Platinum crucible thermocouple inadequacies are thermoelectric power, low thermoelectric power rate, sensitive reading, low mechanical strength at high temperature, very sensitive to pollution, and precious metal materials are expensive, so the one-time investment is relatively large.
The platinum rhodium thermocouple works on the principle that a platinum rhodium thermocouple is formed by joining two conductors of two different components into a loop. When the temperature of the two junctions is different, a thermal current is generated in the loop.
If there is a temperature difference between the working end and the reference end of the thermocouple, the display meter will indicate the temperature value corresponding to the thermoelectric potential generated by the thermocouple.
According to the temperature change of the working environment, the thermostat will have some physical deformations within the switch, resulting in some special effect. The thermostat will cause a series of automatic control element of turning off and turning on, which is also called temperature control switch, temperature controller, temperature protector, referred to the thermostat. Through thermal protector, the temperature protector will send the temperature to the thermostat and the thermostat will send the commands to control the operation of the device in order to achieve the desired temperature and the energy saving effect. Now the thermostat are widely used in thermostat application appliances, motors, cooling, heating and many other products.
The working principle of the thermostat is
automatically sampling, real-time monitoring through the temperature sensor.
The control circuit starts when the ambient temperature is higher than the
control set point. If the temperature still rise, when the temperature rose to
over-limit alarm set point, the thermostat start limit alarm function. When
temperature control can not be effectively controlled in order to prevent
destruction of the device also can be stopped by the trip device features
continue to run.
According to the function of the working,the thermostat have different types:Intelligent Thermostat,Remote Controlled Thermostat,Programmable Thermostat,Wireless Room Thermostat.
