Through the combination of a mechanical measuring system and precise electronic signal processing, the process temperature can be read securely, even if the power supply is lost. The built-in Bourdon tube system generates a rotational pointer movement that is proportional to the temperature. An electronic angle encoder (non-contact, and therefore completely free from wear and friction) determines the position of the instrument pointer. From this, the electrical output signal, proportional to the temperature, is produced. The basis of the intelliTHERM® comes from instrument variants derived from the the model 70 expansion thermometers (see data sheet TM 81.01).
