Product Description

Product Introduction

WRNK-191 is an armored thermocouple based on K-type thermocouple technology, which belongs to industrial temperature sensor. Its core structure is composed of Ni-Cr (positive electrode) and Ni-Si (negative electrode) alloy wires, which are covered with stainless steel protective sleeve (armor layer) and filled with insulating materials such as magnesium oxide, forming a solid overall structure.

Product Advantage

1.Wide temperature measuring range

It basically covers the middle and high temperature range common in industrial production, and is suitable for temperature monitoring requirements in most fields such as heat treatment, metallurgy and chemical industry.

2.Armored structure enhances durability

Stainless steel or nickel-based alloy armored protective sleeve is used, and high-density insulating material is filled inside, which is vibration-resistant and impact-resistant, and can adapt to complex and harsh industrial environment (such as strong corrosive gas and dust pollution).

3.Fast thermal response

The armor layer is closely combined with the temperature measuring element to reduce the heat transfer delay, and the response time is usually ≤5 seconds (depending on the probe diameter), which can capture the temperature change in time.

4.Flexible and bendable

The armored thermocouple can be bent as a whole, which is convenient for installation in complex structural equipment, such as pipeline elbows and narrow spaces.

5.Adapt to a variety of environments

By selecting different materials of armored protective sleeve , it can deal with different corrosive media such as acid, alkali and sulfide, and expand the application scope.

Product Operate Guide

1. Selection of Thermocouple Type
Choose the appropriate thermocouple type (e.g., K, J, T, S) based on the temperature range of your application. 
2. Installation Preparation
Ensure the thermocouple probe is clean and free of damage (e.g., cracks in the sheath). For accurate readings, position the sensing junction (the tip) directly in the area where temperature needs to be measured—avoid contact with non-target surfaces like walls or pipes, unless measuring surface temperatures.
3. Electrical Connection
Connect the thermocouple wires to a compatible temperature controller, data logger, or meter. Match the positive (usually red) and negative (often blue) leads to the corresponding terminals on the device. Use extension wires of the same thermocouple type to avoid measurement errors from temperature gradients in the connection lines.
4. Operation
Power on the measurement device and allow the thermocouple to stabilize—response time varies by design, but most reach steady readings within seconds. Monitor the display for real-time temperature data. Avoid exposing the thermocouple to excessive vibration, mechanical stress, or corrosive environments beyond its rated limits.
5. Maintenance and Storage
After use, inspect the thermocouple for wear, corrosion, or bending. Clean the probe with a soft cloth or appropriate solvent (avoid abrasive materials). Store in a dry, cool place, coiled loosely to prevent wire damage. Replace the thermocouple if readings become inconsistent or the sheath is compromised.
Follow these steps to ensure reliable, accurate temperature measurements with your thermocouple. Always refer to the manufacturer's specifications for model-specific guidelines.

Product Uses

1.Industrial furnaces and heat treatment equipment
Monitor the temperature in box furnace, well furnace and vacuum furnace, and control the quenching and annealing process of metal materials.
2.Chemical reaction kettle and pipeline
Measure the temperature of materials in the reaction kettle and the temperature of high-temperature gas or liquid in the pipeline to ensure that the chemical reaction is carried out at the set temperature.
3.Electricity industry
It is used for temperature monitoring of boilers, steam turbines and other equipment in power plants to ensure the safe operation of power generation equipment.
4.Food and pharmacy
Monitoring temperature in sterilizer, drying box and other equipment meets the requirements of the industry for temperature control accuracy and hygiene and safety.
5.New energy field
For example, in the solar thermal power generation system, the high temperature of the heat collector, heat storage tank and other parts is monitored to optimize the energy conversion efficiency.
