Product Introduction

thermocouple

Sheathed /Assembly Thermocouple

Armored thermocouple is used as temperature measuring sensors to directly measure or control the temperature of fluid, steam and gas media and solid surfaces in the range of 0-1800 ° C in various production processes. Like industrial assembly thermocouples, it is used as a sensor to measure temperature and is usually used with display instruments, recording instruments and electronic regulators. It can be equipped with a temperature conversion circuit to convert the measured value to analog quantities such as 4∽20ma or 1∽5v to achieve long-distance transmission of the measured value.  

Micro sheathed thermocouple

The micro-armored thermocouple is that the temperature sensing element of the armored thermocouple is in direct contact with the measuring medium without additional protective sleeve. The series of products are generally used in the field working conditions are not bad, that is, no wear, strong corrosion and other special requirements, and require a faster reaction occasions. All adopt armored structure, anti-vibration, high temperature measuring speed, long service life. A variety of wiring forms for users to choose, to meet the requirements of various space size. The multi-pair product structure can be adopted to meet the needs of temperature measurement at different locations.

Sensing probe

The sensing part housing is composed of superalloy, which is different from the test requirements and operating conditions such as temperature and pressure. Various forms of temperature measuring materials can be selected, such as armored thermocouples, fiber insulated thermocouples, alloy air tubes, etc. Applied in aerospace engines and other special fields for temperature, pressure, temperature and pressure composite test.

High temperature compensation conductor

The compensating wire has the following characteristics：

Superalloy capillary

Capillary property of Superalloy: it has good softness, corrosion resistance, high temperature resistance, wear resistance and tensile strength It has the advantages of high performance of electromagnetic shielding and waterproof. The capillary energy of Superalloy can be bent freely into various angles and The curvature radius has the same softness and durability in all directions; Flexible pitch, good It has the characteristics of scalability, no blockage and rigidity, and the minimum diameter can be 1m and the wall thickness is 0.02mm.

Superalloy

Superalloy is based on iron, nickel and cobalt, which can grow at high temperature above 600 ℃ and under certain stress，It is a kind of metal material with excellent high temperature strength, good oxidation resistance and hot corrosion resistance，Good fatigue properties, fracture toughness and other comprehensive properties, also known as "super alloy", mainly used in aerospace And energy.

Main product brands: 310S, Incoloy825, inconel600, GH3030, gh3039Materials, plates and pipes.

High-temperature armored triaxial cable

High-temperature armored triaxial cable is composed of metal electrode core wire, inner shielding layer and outer shielding layer.
