Resistance Temperature Detector
TM Tecnomatic RTD are carefully selected to meet the basic resistance values and accuracies specified from IEC 60751 Nominal resistance value is 100ohm at 0° C. Standard bulbs have platinum or Nickel wound resistance elements, with hard glass or ceramic base. One, two or three windings are available on the same bulb. Resistance thermometer bulbs always take up the mean value of the temperature operating over the full winding length, therefore it is important that the full length of the element is exposed to the medium whose temperature is to be measured. Trouble free working of resistance thermometer bulbs is dependent on proper care being taken in their Installation and the selection of associated components used for this purpose. For this reason we recommend the use of TM resistance inserts. TM Tecnomatic resistance thermometer inserts are built-up from nickel or st. tube. Standards inserts size are 4, 6 or 8mm O.D. Resistance thermometer bulbs conforming to most other known international standard are already available upon request.
