WRP series High temperature noble metal thermocouple Divided into three types: S type thermocouple (10- platinum and Rhodium Platinum thermocouple), R type thermocouple (13- platinum and Rhodium Platinum thermocouple), B type thermocouple (30- platinum rhodium 6 thermocouple), mainly divided into single and double platinum rhodium, applicable to all kinds of high temperature, is widely used in the production process of glass, ceramics and other industrial salt bath furnace in the temperature measurement. The S type thermocouple is currently one of the most commonly used industrial. Due to the measurement of high temperature, high temperature resistant stainless steel protection tube generally only up to 1000 degrees, 1000 degrees above the resistance of stainless steel protective tube is expensive, it is commonly used in corundum ceramic protection tube, high purity corundum tube can withstand high temperatures up to 1600 degrees, the disadvantage is fragile.

Two, work principle:

WRP series <strong> high temperature noble metal thermocouple</strong> is composed of two different components of the conductor is connected to the two ends of the synthetic circuit, when the two junction temperature at the same time, will be in the heat generated within the current loop. If the working end and the reference thermocouple endthere is atemperaturedisplay, will be a corresponding display instrument instructions from thermocouples thermoelectric temperature value.

Three, the main part of:

WRP series high temperature thermoelectric noble metal thermocouple heat will increase with 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.

Four, application:

WRP series high temperature noble metal thermocouple made of precious metal 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.

Five, technical parameters:

Thermocouple is a kind of traditional temperature measuring element with thermoelectric stable performance, strong oxidation resistance, suitable for continuous use in oxidizing and inert atmosphere. The long-term use temperature of 1600 DEG C, short term use temperature of 1800 DEG C. The technical indicators are as follows:

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

2, measurement accuracy: < + 0.5% t;

3, time constant: less than 180s;

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

5, size: 50075010001200 (mm).
