WRP series S type thermocouple Also called single thermocouple, Division No. S is its main measurement index number, 0~1600 degrees of medium temperature, is a category of noble metal thermocouple. The normal use in high temperature coking plants, steel mills and other occasions. The measurement for 800~1300 degrees Celsius in the normal temperature of the long-term use of the highest accuracy, while in the 800 DEG C temperature measurement accuracy is not high, but the long-term use temperature of 1300 DEG C it is easy to damage the thermocouple, so choose the right of thermocouples is an important factor to ensure the accuracy of temperature measurement.

Two, work principle:

S type thermocouple is composed of two different components of the grounding conductor ends of synthetic circuit, when the two junction temperature at the same time, it will produce thermal current in the loop. If the working end and the reference thermocouple endthere is atemperaturedisplay, will be a corresponding display instrument instructions from thermocouples thermoelectric temperature value.

S type thermocouple thermoelectric heat will increase as the increase of temperature measurement terminal, its sizeonly withthermocouple materials and ends of the temperature, and thermal electrode length and diameter of the independent. All kinds of rhodium thermocoupleappearanceoftenbecause the needs and not the same, but their basic structures are roughly the same, usually composed of a thermal insulating sleeve, electrode protection tube and terminal box main components.

Three, application:

WRP series S type thermocouple The use of precious metals of high pure platinum as anode and platinum rhodium alloy as cathode, suitable for high temperature applications in various production processes, widely used in powder metallurgy sintering, bright furnace, vacuum furnace, smelting furnace, glass, ceramics andindustrialfurnaceandsalt bath furnace temperature.

Four, technical parameters:

WRP series S type thermocouple Is a traditional temperature measuring element with thermoelectric, stable performance, strong oxidation resistance, suitable for continuous use in oxidizing and inert atmosphere. Long term use temperature of 1600, short term use temperature of 1800. The technical indicators are as follows:

1, the temperature range of 0~1800 DEG c;

2, accuracy: < + 0.5% t;

3, time constant: less than 180s;

4, insulation resistance: 5M ohm (20 DEG C);

5, size: 50075010001200 (mm).
