The thermocouple WRNR2-15 is a double-branch thermocouple designed for low-temperature and low-pressure environments. It is widely used for temperature measurement in power stations, industrial boilers, steam pipes and other places. The product adopts advanced manufacturing technology and materials to ensure high accuracy and high reliability. Its double-branch design not only improves the accuracy of measurement, but also enhances the redundancy of the system. Even if one of the thermocouples fails, the other can still work normally, thus ensuring the continuity of temperature monitoring.

Product Features

(I) High-precision measurement

The WRNR2-15 thermocouple uses a high-precision temperature sensing element, which can accurately measure temperature changes and ensure the accuracy of the measurement results. Its accuracy level is divided into level I and level II. Users can choose the appropriate accuracy level according to actual needs to meet different measurement requirements.

(II) High reliability

The protective tube is made of 1Cr18Ni9Ti stainless steel material, which has good corrosion resistance and mechanical strength, and can operate stably for a long time in harsh industrial environments. In addition, the heat sleeve design makes the installation and replacement of thermocouples more convenient, reducing maintenance time and cost.

(III) Easy maintenance

The heat-shrink design is not only easy to install and replace, but also improves the redundancy of the system. Even if one of the thermocouples fails, the other can still work normally, thus ensuring the continuity of temperature monitoring. This design is particularly important in industrial applications because it can reduce economic losses caused by equipment downtime.

(IV) Multiple installation methods

WRNR2-15 thermocouples provide a variety of installation methods, including threaded connection, flange connection, etc., which can adapt to different industrial environments and equipment requirements. Users can choose the appropriate installation method according to the actual application scenario to ensure the stability and reliability of the thermocouple.

Thermocouples WRNR2-15 are suitable for a variety of industrial scenarios. The following are several typical application cases:

(I) Power station

In power stations, WRNR2-15 thermocouples are widely used for temperature monitoring of generator sets and auxiliary equipment. By accurately measuring the operating temperature of the equipment, potential fault hazards can be discovered in time to ensure the safe operation of the power station. For example, installing WRNR2-15 thermocouples in the bearings of steam turbines and the stator windings of generators can monitor temperature changes in real time to prevent equipment from overheating and damage.

(II) Boiler

In industrial boilers, WRNR2-15 thermocouples are used to monitor the operating temperature of the boiler to ensure that the boiler operates within a safe temperature range. By accurately measuring the temperature of the combustion chamber, flue and water-cooled wall of the boiler, the combustion process can be optimized, the thermal efficiency of the boiler can be improved, and the boiler can be prevented from bursting due to overheating.

(III) Steam pipeline

In steam pipelines, WRNR2-15 thermocouples are used to measure the temperature in the steam pipeline to prevent overheating or overcooling. By real-time monitoring of the temperature of the steam pipeline, it can be ensured that the temperature and pressure of the steam are within the specified range, thereby ensuring the normal operation of the steam system. In addition, WRNR2-15 thermocouples can also be used to monitor the insulation effect of the steam pipeline to prevent heat loss.

(IV) Chemical industry

In the chemical industry, WRNR2-15 thermocouples are used to measure the temperature during chemical reactions. By accurately measuring the temperature in the reactor, heat exchanger and pipeline, it can be ensured that the chemical reaction is carried out under the optimal temperature conditions, improving the reaction efficiency and product quality. At the same time, the WRNR2-15 thermocouple can also be used to monitor the operating temperature of the equipment to prevent the equipment from malfunctioning due to overheating.

In order to ensure the long-term stable operation of the Thermocouple WRNR2-15, it is recommended to perform the following maintenance and care regularly:

(i) Appearance inspection

Regularly check whether the protective tube has physical damage, such as cracks, dents or corrosion. If the protective tube is found to be damaged, it should be replaced in time to prevent damage to the thermocouple.

(ii) Check fasteners and connections

Make sure all screws and fasteners are properly fastened, and check the tightness and corrosion of the cable connection. If the fasteners are found to be loose or the cable connection is poor, they should be tightened and repaired in time to ensure the stability and reliability of the thermocouple.

(iii) Regular calibration

Perform electrical calibration regularly to ensure measurement accuracy. It is recommended to perform calibration once a year to ensure that the measurement results of the thermocouple are accurate and reliable. During the calibration process, a standard temperature source should be used for calibration, and the calibration results should be recorded.

(iv) Clean the protective tube

Clean the protective tube regularly to prevent dust and dirt from affecting the measurement results. During cleaning, use soft cloth and mild detergent, and avoid using hard objects or corrosive detergents to avoid damaging the protective tube.

Thermocouples WRNR2-15 are widely used in the field of industrial temperature measurement due to their high accuracy, high reliability and easy maintenance. Through reasonable maintenance and care, their service life can be further extended to ensure the long-term stability and accuracy of temperature measurement. Whether it is a power station, boiler, steam pipeline or chemical industry, WRNR2-15 thermocouples can provide reliable temperature monitoring solutions to ensure the smooth progress of industrial production.
