A complete measuring point consists of a measuring insert which contains the basic sensors, the protective fitting and an optional measurement value processor (transmitter).

The basic sensors are:

• Resistance thermometers:
  Temperature measurement is based on the temperature dependency of the installed measuring resistor.
• Thermocouples:
  Temperature measurement is based on the Seebeck effect. A thermocouple which subjected to a temperature drop produces thermoelectric voltage that can be measured.

Transmitters:

The optional Siemens transmitters assume the following functions:

• Optimum measurement processing
• Strengthen weak sensor signals directly on site.
• Transmit standardized signals
• Protect against electromagnetic interspersion
• Option to conduct measuring point diagnostics.
