Ferro Temperature Sensing Ring | Ceramic Firing Temperature Measurement Tool

Ferro PTCR Temperature Control Rings

Ferro PTCR (Process Temperature Sensing Ring) are high-precision ceramic firing temperature indicators specifically designed for accurate temperature detection in high-temperature sintering processes in ceramics, السيراميك الالكتروني, المواد المغناطيسية, and powder metallurgy.

Traditional thermocouples can only measure the ambient temperature inside the furnace, failing to fully reflect the cumulative thermal effects of radiant heat, conductive heat, and holding time on the product itself. Ferro PTCR temperature control rings, through their own high-temperature contraction and shrinkage, accurately record the comprehensive thermal process experienced by the product during firing and convert it into a corresponding equivalent temperature, providing a reliable basis for kiln temperature calibration, temperature uniformity analysis, and process optimization.

The product is suitable for various high-temperature firing equipment such as continuous kilns, أفران النفق, roller kilns, bell kilns, shuttle kilns, and box furnaces, and can be used in different atmospheric environments including oxygen, نتروجين, air, فارغ, and reducing atmospheres.

ميزات المنتج

1. Accurately Records the Comprehensive Thermal Effect of Product Firing

Unlike thermocouples, which only measure ambient radiant heat, the PTCR high-precision ceramic firing temperature indicator can simultaneously measure radiant heat, conductive heat, and the cumulative thermal effect of time and temperature throughout the entire firing process. It faithfully records the actual thermal process experienced by the product during firing, making it an effective tool for measuring the product’s own thermal state.

2. High-Precision Measurement, Error ≤3℃

The temperature ring is a reliable, high-precision product with a maximum error of less than 3℃ and an accurate temperature difference of up to 1.5℃. By measuring the shrinkage of the temperature ring after firing (reduction in outer diameter) and referring to the corresponding temperature conversion table and calibration curve for that batch of products, the equivalent temperature can be obtained.

3. Adaptable to Multiple Atmospheres and Kiln Types

Suitable for various firing atmospheres such as oxygen, نتروجين, air, فارغ, and reduction. Widely used in various kilns including discontinuous and continuous tunnel kilns, shuttle kilns, roller kilns, bell kilns, box kilns, tube kilns, and vertical kilns.

4. Standardized Size, Easy to Use

Outer diameter 20mm, inner diameter 10mm, thickness 7.0mm. 15 pieces/small box, 600 pieces/large box. Measure the outer diameter after firing using a digital micrometer and refer to the temperature conversion table to obtain the equivalent temperature. Each thermometer is specially designed for this batch of temperature measuring rings; the production batch number must be consistent with the temperature conversion table. Maximum error is less than 3℃, and the accurate temperature difference can reach 1.5℃. Can be placed anywhere inside the furnace, on the push plate, or on the conveyor belt; no temperature measurement is required before use.

الأسئلة المتداولة (التعليمات)

1. What are Ferro PTCR temperature sensing rings mainly used for?

They are mainly used for detecting the actual temperature during high-temperature sintering processes in ceramics, السيراميك الالكتروني, المواد المغناطيسية, تعدين المساحيق, إلخ., to analyze the true heating conditions of the product.

2. What is the difference between a temperature sensing ring and a thermocouple?

Thermocouples mainly measure the ambient temperature at a specific point inside the furnace, while temperature sensing rings record the cumulative thermal effects experienced by the product, including radiant heat, conductive heat, and the influence of holding time, thus more closely approximating the actual firing temperature of the product.

3. Can temperature sensing rings be reused?

Ferro PTCR temperature sensing rings are single-use testing elements. Temperature analysis is performed after firing based on dimensional changes, and they are generally not reused.

4. What temperature range are applicable to temperature sensing rings?

Depending on the model, they can cover a temperature range of approximately 649℃ to 1750℃. The appropriate model can be selected based on the actual sintering process.

5. How to determine the test temperature of the temperature sensing ring?

After firing, the change in the outer diameter of the temperature measuring ring is measured using a digital micrometer. Combined with the corresponding batch temperature conversion table provided with the product, the actual equivalent temperature can be obtained.
