The installation position of explosion-proof heat resistance can affect the measurement standard

We in the explosion-proof heat resistance for installation, it is important to note the accuracy of the measurement, as well as maintenance and security issues, but not on the equipment running, or any impact on the normal production and operation, must meet the above requirements, should be considered heat resistance installation position and the depth of insertion.

a, if the explosion-proof heat resistance with a protective casing, so will cause a certain loss to heat transfer and heat dissipation, in order to reduce the measurement error, so whether thermal resistance, thermocouple in the depth of the insert should have certain request, this is must be clearly marked.

2, if it is installed in the pipeline of the measuring center, on the basis of the temperature of the fluid in the explosion-proof heat resistance, under normal circumstances, in the depth of the insert should be guaranteed in the center of the pipe, or with the method of vertical and inclined installation, both installation way can effectively ensure the normal use of thermal resistance.

3, for high temperature and high pressure fluid on temperature measurement, explosion-proof heat resistance in order to reduce the case, may be on fluid resistance, lead to the fracture phenomenon, can choose shallow insertion way, to protect the pipe sleeve, and use of the thermal resistance of thermal sleeve is inserted.

4, need to measure in the flue gas temperature, then for explosion-proof thermal resistance, although the flue met 4 m in diameter, but the thermal resistance in the depth of the insert as long as the guarantee in 1 m is ok; And beyond the insertion depth of 1 m, is the use of the vertical installation, to support or to protect casing.

5, in order to keep the explosion-proof heat resistance on the measurement of end, and have sufficient heat exchange between the measured medium ability, for the position of the measuring point on the choice is very important, try not to select in the position of the valve, because the installation will affect the thermal resistance measurement standards, can be installed on the device of a corner position.
