WZPN Wear resistance thermal resistance produced by SHANGHAI AUTOMATION INSTRUMENTATION CO. LTD. is the power plant circulating fluidized bed boiler, boiling boiler, pulverizer gas furnace and cement plant series kiln head, kiln tail, furnace hood and chemical, smelting and other high temperature wear environment is ideal for high-tech Special products.

Overview

Wear-resistant thermal resistance and wear-resistant thermocouple are the same as the power plant circulating fluidized boiler, boiling boiler, pulverizer gas furnace and cement plant series kiln head, kiln tail, furnace hood and chemical, smelting and other high temperature wear The environment is more ideal for high-tech special products, wear-resistant thermal resistance Bocaizhongchang, using a unique formula, in the balance in the production of wear-resistant alloy alloy products and ordinary stainless steel metal, metal ceramic protection tube, and the market similar wear-resistant alloy Protection of the pipe compared to its life increased by 1-5 times due to the ambient temperature difference, the temperature control point is too high, vibration, blower wind speed is too high, serious wear and tear, resulting in temperature measurement is very difficult, very short life, Wear-resistant alloy only 10-90 days to wear damage, burning bend, broken, resulting in thermal resistance damage, to the user a lot of loss and unnecessary trouble, wear-resistant thermocouple make up for this shortcoming.

Wear resistance thermal resistance erosion, wear resistance of hundreds of manufacturers, the use of nearly ten thousand times a year, the response is very good, in many occasions with the leading peer strength, can be comparable with the imported products. Resistance to thermal resistance with anti-vibration , Wear resistance, corrosion resistance, high sensitivity, good stability, high accuracy, long life and other advantages, is today's power plants, cement plants, chemical smelters and other wear-resistant areas of the preferred temperature measurement protection tube.

Principle of temperature measurement

The principle of temperature measurement is based on the conductor or semiconductor resistance with the temperature changes in the characteristics of change. Its advantages are many, but also remote signal, high sensitivity, stability, interchangeability and accuracy are better, but the need for power excitation, can not instantaneous measurement of temperature changes. Different conductors have different electron densities because their electrons are different so that they produce a certain amount of electron diffusion. When they reach a certain equilibrium, the magnitude of the contact potential depends on the material properties of the two different conductors and their contact Point of temperature.

Wear-resistant thermal resistance using three-wire system is to eliminate the connection wire resistance caused by the measurement error. This is because the circuit that measures the thermal resistance is generally an unbalanced bridge. Thermal resistance as a bridge arm resistance, the connection wire (from the thermal resistance to the control room) has become part of the arm resistance, this part of the resistance is unknown and with the ambient temperature changes, resulting in measurement error. Using a three-wire system, the wire connected to the power supply side of the bridge, the other two were connected to the thermal resistance of the bridge arm and its adjacent arm, thus eliminating the wire line resistance measurement error.
