Bimetallic temperature and humidity meter structure characteristics and working principle

Li bimetal light night light socket, its principle is to use round shape into threaded hot metal as a temperature sensing element, fixed at one end, and the other end is connected on a thin shaft, shaft end have good Pointers. When the temperature and humidity change, deformation of the free end of the heat element will immediately turn, promoted the pointer and so thin shaft angular displacement, shows the change of temperature and humidity on the dial; Perform a table by steering transmission mechanism to move the pointer. < / p > < / p > due to the heat moisture element and is a linear relation with the temperature change, therefore, bimetallic night light socket pointer is indicating the position of the measured temperature of environment. < / p > < / p > bimetallic night light socket materials generally have steel, cast alloy, stainless steel plate, plastic; Detecting element and core pulling structure; Adjustable Angle the header part of the thermometer with corrugated pipe, Angle of institution, etc, can from the Angle to the straight type, or is, in turn, from the Angle of straight to the Angle of transformation. < / p > < / p > bimetallic thermometer is the use of two different kinds of metal elements in the process of temperature change caused by the expansion degree of different principle to work, in order to improve the sensitivity of the measuring temperature humidity, generally the metal support spiral coil shape. When multi-layer metal temperature change, the layers of metal expansion or contraction, yes spiral coil rolled up or let go. As a result of the spiral coil is fixed at one end, and the other end is connected with a pointer is free to rotate, so, when the bimetallic strip feel the change in temperature, Pointers can on a circular dividing scale to indicate the temperature. < / p > < / p > in general, the home of bimetallic thermometer instrument used for measuring temperature range is in - 60 ~ 120 ℃, accept the error is within the scope of scale about 3% of the two processes. < / p > < / p > light, professional development and production of sales of all kinds of night light socket, product by retailers, boutique, gifts, traders trust and love. Welcome friends from all walks of life business consultation understand < / p > post: light night light socket ea - gl。 com < / p > < p > < / p >
