One of the most popular design i.e. The target markets of this thermometer are air-conditioning and machine building. It therefore has no capillary and the temperature is read on the dial directly at the place where the temperature is measured. Bimetallic strips are one of the oldest techniques to measure temperature. 0000035285 00000 n 0000046081 00000 n Bimetallic strip can be used in direct indicating type thermometers. The working principle of a bimetallic thermometer is illustrated in figure below. Bimetallic thermometers with inox case, rear stem, with pocket, DN 40–50–63–80–100 RD 63-80-100 VI Radial stem thermometers, liquid expansion, with pocket, DN 63–80–100 0000067862 00000 n The working of a bimetallic strip thermometer is based upon the fact that two dissimilar metals behave in a different manner when exposed to temperature variations owing to their different thermal expansion rates. On a large scale, it can provide literally tones of force for mechanical control or other purposes. It is usually observed in applications like an iron box, heaters, kettles, etc. 0000009856 00000 n The models A52, R52 bimetallic thermometers are the entrylevel model among process thermometers. 0000004221 00000 n Method of Operation The measuring element of the bimetallic thermometer is a fast-response bimetallic helix. 0000021465 00000 n In thermometer, the bimetal strip is used in coil form. 0000035392 00000 n These types of thermometers work best at higher temperatures, since their accuracy and sensitivity tends to reduce at low temperatures. 0000012062 00000 n A bimetallic strip converts thermal energy into mechanical displacement. For instance, we offer 2.5″ to 5″ dial sizes. a household thermometer. ��:��;�kݬ�5���^���`�_ 9���ӄ���e��9;evN�������E]ݢJۜ�c��ReW2��*�'8�H�4銬���^�WZ�����&�c1F&Cz�P4��5����x!�Q\�DMV�`j@��������L�5�?�\���o�H'x�)���t�o^�eA�3���y�0����������N��Q\���j��#����&^�2��c�s�kM� �#"�����+ �Ef+{�q���]N(͕����>|?RP n�1��}$=�k$�U�v�ȏ���W��M�K|�zQ��ŧ,�g�2���������"�.�~,����3"�P[=���}��ُ�/���/�Ԙ��ęg$tWnE�TlrFB����Z�S:.�h��ټ��c����+��M����8����ƽ�S�J�� ���Ts5~@����ԺZh�JE$�ܶ�Ɨ�s�z�n%�Oת��2��� %���5���Ju ��x��T�Ȧe�$� 3�����gMC�J/�I�C�?���;-'��y�Q�4��0>�F+9}}{���w '�%�� i�l`��0Pp���Rų۝�u��o6C�C���R Ss>���u=@&���-�-R8��n���������S���*�#���W����}��x��q��Isl�OG�ϊ{�����-q|« =�����"L9 .�E]m#a����hJ���.����4�DMɱ._5��i�����7V��N5[ƽ���ٯj�������M��aB�W93�*�Q��dմ���� Bimetallic strips often come in very long sizes.

One of the most popular design i.e. The target markets of this thermometer are air-conditioning and machine building. It therefore has no capillary and the temperature is read on the dial directly at the place where the temperature is measured. Bimetallic strips are one of the oldest techniques to measure temperature. 0000035285 00000 n 0000046081 00000 n Bimetallic strip can be used in direct indicating type thermometers. The working principle of a bimetallic thermometer is illustrated in figure below. Bimetallic thermometers with inox case, rear stem, with pocket, DN 40–50–63–80–100 RD 63-80-100 VI Radial stem thermometers, liquid expansion, with pocket, DN 63–80–100 0000067862 00000 n The working of a bimetallic strip thermometer is based upon the fact that two dissimilar metals behave in a different manner when exposed to temperature variations owing to their different thermal expansion rates. On a large scale, it can provide literally tones of force for mechanical control or other purposes. It is usually observed in applications like an iron box, heaters, kettles, etc. 0000009856 00000 n The models A52, R52 bimetallic thermometers are the entrylevel model among process thermometers. 0000004221 00000 n Method of Operation The measuring element of the bimetallic thermometer is a fast-response bimetallic helix. 0000021465 00000 n In thermometer, the bimetal strip is used in coil form. 0000035392 00000 n These types of thermometers work best at higher temperatures, since their accuracy and sensitivity tends to reduce at low temperatures. 0000012062 00000 n A bimetallic strip converts thermal energy into mechanical displacement.
