Overview

Overview: The anti-corrosion platinum resistor is a specially designed and manufactured temperature sensor by our company, specifically designed for measuring the temperature of highly corrosive media such as sulfuric acid, hydrochloric acid, phosphoric acid, strong oxidants, organic solvents, etc. with a temperature ≤ 220 ℃

Product Details

summary:

Anti corrosion platinum resistors are carefully designed and manufactured by our company, specifically targeting sulfuric acid, hydrochloric acid, phosphoric acid, strong oxidants, and organic compoundsSpecial temperature sensor for measuring the temperature of highly corrosive media with solvent temperature ≤ 220 ℃.

characteristic:

1. The anti-corrosion platinum resistor adopts multi-layer anti-corrosion (anti-corrosion thermal resistance anti-corrosion layer protective tube is usually thick walled)316L or 904LThe structure of sintered polytetrafluoroethylene layer and wear-resistant anti-corrosion layer on the outside of the steel pipe has been verified by many domestic enterprises for its anti-corrosion effect and service life through long-term use.
2. Our company adopts the most advanced domestic PTFE anti-corrosion coating for anti-corrosion platinum resistorsIntegrated sintering processMade by sintering, it solves the problem of seam leakage that cannot be avoided by other manufacturing processes. The application of this technology has enabled our company's anti-corrosion thermal resistors and other anti-corrosion products to have an average service life of over one year (in an environment without significant wear and tear).
3. At the site of use, there is often severe erosion of the thermal resistance anti-corrosion layer by high velocity measured medium particles. Our company's anti-corrosion thermal resistance has a layer of wear-resistant material outside the anti-corrosion layer, which can effectively extend the service life of the anti-corrosion layer by 8-10 times in environments with erosion, unlike other similar anti-corrosion sensors in China.

Technical indicators:
1. Anti corrosionplatinumThe thickness of the PTFE anti-corrosion layer for the resistor is 1.0mm (can also be specified by the user).
2. Thermal response time of anti-corrosion platinum resistance: After anti-corrosion treatment, the thermal response time changes by about 20%;
3. Quality inspection of anti-corrosion coating for anti-corrosion platinum resistance: using electric spark micro hole inspection, voltage 12kV, frequency 1.6 × 106Hz without breakdown.
4. The working pressure of the anti-corrosion platinum resistor: The maximum operating pressure for fixing the anti-corrosion thermal resistor is 4.0MPa when it is installed on a flange; The maximum operating pressure for fixing the anti-corrosion thermistor with F4 thread connection is 0.6MPa.
5. The other technical indicators of the anti-corrosion thermistor are the same as those of ordinary industrial platinum resistors.
