Bimetallic thermometer application core pulling type

Core pulling type bimetallic thermometer application

how it works:

core pulling type bimetallic thermometer is a kind of measurement in the field of low temperature test instrument. Used in chemical industry, medicine and other fields. Can be directly measured in the process of various production - 80℃- Liquid + 500 ℃ range steam and gas medium temperature. Bimetallic thermometer is mainly used in industry of element is one with two or more pieces of metal laminate composed of multilayer metal together, using two different metal working in the principle of expansion degree of different temperature changes. Is based on the ring around made of bent bimetallic strip. End is heated expands, turns the pointer, the instrument will show thermoelectric potential should value.

core pulling type bimetallic thermometer is simple said the temperature sensing element in the head with argon arc welding is fixed on the bottom of the protecting tube, when the thermometer is failure, failure, damage, or other conditions, only interrupted production can replace the new table. Bimetallic thermometer and core pulling type, the header and the thermal element into an organic whole, the external protecting tube and fittings together again, when need to replace the new table as long as the header part from the external protecting tube fixed on the equipment out change into another new header. Replace the new table with two or three minutes to complete, do not need to stop replacing. At present, the general use of the bimetallic thermometer if you need to start up production to replace the new table not must plus outer casing. Such as spent two casing, which greatly increased the temperature response time, reduces the sensitivity, and with the two casing, increased the unit using the economic burden.
