WZPN-431 Abrasion resistant RTD

WZPN-431 Abrasion resistant RTD

Overview

WZPN-431 Abrasion resistant RTD is a high-tech class that is ideal for high-temperature wear-resistant environments such as power plant circulating fluidized bed boilers, boiling boilers, pulverized coal gasifiers and cement plant series kiln heads, kiln tails, furnace head covers, chemical industry, and smelting Special products.

Working Principle

The temperature measurement principle of WZPN-431 Abrasion resistant RTD is based on the characteristic that the resistance value of the conductor or semiconductor changes with the temperature. Different conductors have different electron densities. Because of their different electron densities, a certain amount of electron diffusion occurs. When they reach a certain balance, the potential formed by the contact potential depends on the material properties of the two different conductors and their contact. Point temperature. It uses a three-wire system to eliminate the measurement error caused by the resistance of the connecting wire.
