The installation of the bimetallic thermometer use matters needing attention

1) bimetallic thermometer protecting tube insertion of the measured medium length must be greater than the length of the heat element ( General insertion length should be greater than 100 mm, 0 50 ℃ range insertion length greater than 150 mm) To ensure the accuracy of the measurement. (2) the bimetallic thermometer is in use and installation, should avoid collision protection tube, do not make the protection tube bending deformation. (3) temperature thermometer often work in the biggest range of 1/2 to 3/4. When installation should be clamping hexagonal screw part will be tight, it is forbidden to use the method of rotating header tighten the screw. (4) when measuring temperature above 200 ℃ medium, in addition to the installation joint guarantee seal, still need to pay attention to the influence of thermal radiation on the instrument. Normal use environment temperature for - 20 ~ + 60 ℃, beyond the temperature range should be added protection.
