The TT-2000 Series is a complete stainless steel temperature transmitter, based on a PT-100 element (1/3 DIN class B). The range of standard elements can be set between -50 and 200°C. Other ranges are available on request. The PT-100 element is mounted in a stainless steel plug (sensor position 9). To obtain an accurate and fast measurement, the diameter of the insert part has to be chosen as small as possible. The resistance change of the PT-100 element due to temperature change is converted into a proportional 4-20 mA signal (2-wire). A great diversity in designs and process connections can be made including the milk couplings (DN25, 40 and 50), Tri-clamp (1, 1 ½ “or 2”) and hygienic weld-on-nipples as ¾ “BSP nut (diam. 28 mm). Associated immersion tubes (called Thermo Wells) fully welded and manufactured from execution (called “bar stock”) are available in various designs and materials (on request).
