Bimetallic thermometer term definition

Accuracy: accuracy is the difference between real value and display ( Error) , divided by the temperature span ( Measuring range), Percentage, including: the way to work, the influence of the observer, the appliance environment, including return difference accuracy error, repeatability, but does not include friction error. Adjustable adjustable pointer display: indicate, this change to include the whole scale. The adjustable are usually adjustable pointer, rotatable dial, or other similar parts. If you can provide this kind of adjustable will widely thermometer user acceptance. Shell: support, protection and tolerance in machine shell or cover, including the dial, pointer, shell design according with the pointer location and scale value, and has a transparent table cover; Thermal head: generally described is the part of the heat pipe is sensitive to temperature. Casing: usually the device attached to the appearance of thread, generally no compression sheath; Teeth: used to connect to stand and casing, or stand and equipment; Universal: allow pan rotation 360 & deg; Heat pipe can be adjusted at least 180 & deg C; ； Axial: heat pipe and dial into 90 & deg; Fixed Angle; Radial: pipe tube parallel to dial; Bimetallic strip: temperature sensing part, by two or more different metal couplet, due to the different expansion coefficient, cause the bimetallic strip rotation, according to temperature change; Range: the scale of the highest and the lowest limit; Pointer: connected with the dial, indicating temperature components; Table: a transparent protection components, through it can be observed dial; Immersion length: from the thermometer to the immersed part at the end of the heat pipe length, the length should be greater than induction fragments length; Overtemperature damage: the thermometer is put into more than its damage caused in the temperature range, is likely to be environmental problems, may also be a step error.
