.book Page 8 Tuesday, March 6, 2012 10:08 AM 1 PRODUCT FEATURES OPTITEMP TR/TC100 1.3.2 Thermocouples The thermocouple features two electric conductors made from different metals, connected at one end. Each free end is connected to a compensation cable which is then connected to a millivolt meter. This circuitry forms a "thermal circuit". The point at which the two electric conductors connect is called the measuring point and the point at which the compensation cables connect to the conductors of the millivolt meter is called the cold junction. If the measuring point of this thermal circuit...

.book Page 15 Tuesday, March 6, 2012 10:08 AM TECHNICAL DATA 2 OPTITEMP TR/TC100 2.3 Permissible flow speed The maximum permissible flow speed for the measuring insert depends on its immersion depth and on the density of the product. The greater the immersion depth and the higher the density, the larger the load. If the measuring insert is used in the thermowell, the flow speed is irrelevant. If, however, the flow goes against an unprotected measuring insert, its load must be calculated individually. If this is the case, the manufacturer will offer further support. 2.4 Permissible operating...
