Product Details
WSSX-411-B is explosion-proof Bimetal thermometers with electric contact point. It is usually used to measure the temperature of explosion-proof
environment.
Installation requirements
For the installation of bimetal thermometers, attention should be paid to accurate temperature measurement, safety
and reliability, and convenient maintenance, and does not affect equipment operation and production operations. The above requirements must be met. When choosing the installation position and insertion depth of the thermal
resistance, pay attention to the following A few points:
(1) In order to have sufficient heat exchange between the measuring end of the thermal resistance and the measured
medium, the location of the measurement point should be selected reasonably and try to avoid installing thermal resistance near the dead corner of the valve, elbow, pipeline and equipment.
(2) The thermal resistance with protective sleeve has heat transfer and heat dissipation loss. In order to reduce
the measurement error, the thermocouple and thermal resistance should have sufficient insertion depth:
a. For the thermal resistance measuring the temperature of the fluid in the center of the pipeline, the measuring end should generally be inserted into the center of the pipeline (vertical installation or inclined installation). If the pipe diameter of the tested fluid is 200 mm, the insertion depth of the thermal
resistance should be 100 mm;
b. For temperature measurement of high-temperature, high-pressure and high-speed fluids (such as main steam temperature),
in order to reduce the resistance of the protective sleeve to the fluid and prevent the protective sleeve from breaking under the action of the fluid, the shallow insertion method of the protective tube or the hot sleeve type
Thermal resistance. Shallow plug-in thermal resistance protection sleeve, the depth of its insertion into the main steam pipe should not be less than 75mm; the standard insertion depth of thermal sleeve thermal resistance
is 100mm;
c. If you need to measure the temperature of the flue gas in the flue, even though the flue diameter is 4m, the
thermal resistance insertion depth is 1 m;
d. When the insertion depth of the measuring original exceeds 1m, it should be installed as vertically as possible,
or a support frame and protective sleeve should be installed
