Stainless steel bimetallic thermometer error sources have?

Stainless steel bimetallic thermometer is around into threaded thermal bimetallic strip as thermal devices, and put it in a protective sleeve tube, one end is fixed, known as the fixed end, the other end of the connection on a thin shaft, called the free end. Spool at the free end is equipped with a pointer. When the temperature changes, the resulting thermal devices the free end of the rotation, drive the thin axis from the Angle of the pointer changes, corresponding temperature indicator on the dial. Widely used in petroleum, chemical industry, machinery, ships, electricity, textile, printing and dyeing and other industrial and scientific research departments and other fields. So the requirement for the precision is high. Thermometer as a professional manufacturer, combined with our years of experience in the thermometer, sums up the result in the error of the stainless steel bimetallic thermometer five aspects: 1. High precision of the thermometer itself level, level of relative error is much smaller. 2. Heat pipe is sheath maerial of insertion depth, the original depth must be over the temperature of the thermometer ( More than two-thirds of heat tube length) , usually will have a sheath maerial pits, liquid to flow over the pits. 3. Thermal sheath maerial of material, different material heat of reaction time and cooling degree will lead to different precision error is different. 4. Whether the thermometer with a sheath, sheath thickness and material of different can also lead to the reading error of the thermometer and reaction time. 5. Using the environment also can affect.
