Made in China Earth Resistance Tester In Competitive Price

Product performance characteristics

resistance˜ stability: resistance temperature coefficient of 2.17 × 10-4Ω / ℃, high temperature at 350 ℃, the resistance only increased to 2.25 × 10-4Ω / ℃, in the high temperature 648 ℃, the resistance only increased to 3.13 × 10 -- 4Ω / ℃, will help to ensure the protection of the sensitivity.

strong antioxidant˜ capacity: about 1000 ℃ in a high temperature to maintain good oxidation resistance. Suitable for serious environmental pollution.

tolerance of˜ high temperature: the melting point as high as 1500 ℃, short-term temperature rise to allow for 760 ℃; high tensile strength: high-tensile strength, can˜ effectively resist the role of electric power.

high resistivity:˜ resistivity of 1.08μΩ.m, will help reduce the resistance component size;

high toughness: dramatic changes in the operating temperature conditions, remained good toughness and difficult to fracture, long service life (commitment 20 years).

type complete: In accordance with the size of through-flow˜ capacity, a continuous type, grid type, Spiral Wound, Wound ribbed, smooth type, such as winding resistance of a variety of structural types of components;

resistance modular components: the adoption of series and parallel methods can be any combination to suit the capacity of the through-flow, voltage, resistance, such as the requirements of various parameters. Easy to replace.

reasonable thermal design: the structure of cabinets with the best channel˜ cooling airflow, good cooling effect, the elimination of the local high-temperature ignition points and easy points.

Main characteristics

The earthed neutral resistance use professional , special formula of stainless steel alloy material manufacture, its main characteristics are as follows :

1 .Stable resistance to ensure the sensitivity of the product

2. Oxidation ability Under the high temperature of 1000 ℃ can still maintain good oxidation performance, suitable for polluting the environment

3. Resistant to high temperature melting point 1500 ℃, a short time to allow up to 760 ℃

4. High tensile strength can effectively lower the effect of electric power

5. High resistivity Is beneficial to reduce the resistance element size

6. High toughness Under the condition of the operation of the rapid changes in temperature, still keep good toughness, not easy to break, long service life (20 years) promise

7. The type is complete According to the size of the flow capacity, has a continuous belt type, grille type, spiral wound, smooth wound and so on the many kinds of structure resistance element

8. Resistance element modular By string, parallel method, which can be any combination, so as to adapt to the flow capacity, voltage, resistance of various parameters, such as easy to replace

9. Reasonable thermal design of cabinet put oneself in another's position structure which has the best cooling air flow path, the cooling effect is good, eliminates the local high temperature point and burning point

10.Design of long life Ensure the design life of 20 years
