Definitions
- the measuring chain of the thermocouple consists of the thermocouple 1, with thermocouple extension 12, which connects the thermocouple 7 at the cold junction 14 with a cable 7.
- This cable 7 transmits the thermal voltage across the boundary of the explosion-proof room 3 to a signal converter 5 installed in the unprotected room 4, which converts the thermovoltage into a signal current.
- the signal current is conducted via a further cable 7 to the input module 13 of the controller 10.
- the analog signal stream is digitized.
- Typical input modules or input interface are so-called I / O cards that digitize the analog signal stream for further signal processing in the controller 10.
