Wear resistance
Description
In some special occasions, such as chemical plants, smelters, power plants, cement plants, with ordinary thermal resistance, thermal resistance is easy to damage. Therefore, wear-resistant thermal resistance must be used in these occasions. The thermal resistance is especially suitable for measuring temperature of vulcanized bed, coal mill export, primary and secondary air coal and cement industries.
Characteristics of wear-resisting thermal resistance:
On the basis of WR and WZ series, the insert part of the protective sleeve can be made in whole or in part.
Wear resistance, erosion resistance, corrosion resistance.
Long life. It can be used for more than 6 months at high temperature and more than 8 months at low temperature.
Thermocouple, the thermal resistance is armored structure.
Technical specifications of wear-resisting thermal resistance
| name | Dividing sign | Temperature range: ° C | Allowable deviation △ t |
| Nichrome -- nichrome silicon | K | 0 ~ 1200 | ± 2.5 ℃ or 0.75%t |
| Nichrome -- Cupric nickel | E | 0 ~ 600 | ± 2.5 ℃ or 0.75%t |
| Platinum resistance | PT100 | - 100 ~ 500 | ± (0.15+0.002t) |
| Copper resistance | Cu50 | - 50 ~ 100 | ± (0.30+6.0*10-3t) |
*T is the measured temperature of the temperature sensing element.
