OPTITEMP TRA/TCA PLUS 1.1 Temperature assemblies for industrial applications Temperature assemblies for advanced requirements with replaceable measuring inserts can be used in various areas in industrial measuring technology. What sets them apart is the process connection and the thermowell version: multipart welded and one-piece bar stock. • Screw-in temperature assemblies without thermowells can be screwed into existing, welded on thermowells or into machine housings. The range includes DIN variants with M18 x 1.5 mm connection threads and ANSI variants with ½" NPT thread connections. •...

OPTITEMP TRA/TCA PLUS 1.3 Measuring principle All of the temperature assemblies described here belong to the class known as "contact temperature assemblies". Unlike "radiation temperature assemblies", these temperature assemblies come into direct contact with the medium whose temperature they are to measure. The type of measuring principle depends on the measuring insert sensor that you combine with the transmitter. Two different sensor types are available. Their respective measuring principles are described in the following subsections. 1.3.1 Resistance temperature sensor The measuring...

OPTITEMP TRA/TCA PLUS 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 is heated up, a small electrical voltage (thermal voltage)...
