Productoverview:
WRE series Miniature thermocouple Usually use and display instruments, recording instruments, electronic computers and other supporting. Direct measurement of the production process in a variety of -200 to 500 DEG C within the liquid, steam and gas and solid surface temperature.
Two, work principle:
WRE series Miniature thermocouple The electrode is composed of two different conductor materials. When there is temperature difference between the measuring terminal end with the reference, will produce thermal potential, the instrument will display relevant thermal potential temperature.

Three, main features:
1, simple assembly, convenient replacement;
2, the pressure spring type temperature sensing element, good anti vibration performance;
3, large range of temperature measurement;
4, high mechanical strength, good pressure resistance.
Four, technical parameters:
Thermocouple: II;
Heat resistance: A B;
Nominal pressure: pressure.

Five, installation requirements:

The thermocouple installation should pay attention to details; several thermocouples were installed in use; for the temperature measurement is accurate, safe and convenient maintenance, and does not affect the equipment operation and production operation. To meet the following requirements, in the choice of the thermocouple installation position and insert depth should pay attention to the following 2 points:
1, with a protective casing thermocouple heat transfer and heat loss, in order to reduce the measurement error, the thermocouple should have sufficient depth of insertion.
A, when measuring the original insertion depth is more than 1m, should be installed vertically, or installing supporting frame and a protective sleeve.
B, if you need to measure the flue gas temperature is, while the flue diameter is 1000mm, the depth of the thermocouple insert 500mm.
C, for the temperature measurement of fluid pipe center thermocouple, generally the measuring end is inserted into the pipe center (vertical or inclined installation). If the measured fluid pipe diameter is 100 mm, the depth of the thermocouple insert should choose 50~100 mm (should take into account the size installation base or flange).
D, for temperature measurement of high temperature and high pressure and high speed fluid (such as main steam temperature), in order to reduce resistance to the fluid and prevent the protective sleeve to protect the casing fracture under the influence of the fluid, can take the protection tube or shallow inserted by thermal sleeve type thermocouple. Shallow inserted thermocouple protection tube type, which is inserted into the main steam pipeline the depth should be less than 75mm; thermal sleeve type thermocouple standard insert depth 100mm.
2, in order to make the measurement end of thermocouple and measured with sufficient heat exchange medium, should choose a reasonable measuring position, to avoid the valve, elbow and piping and equipment installation thermocouple near the corner.

Six, models and specifications:
