A complete measuring point consists of a measuring insert which contains the sensor elements, the protective fitting and an optional measurement value processor (transmitter). The sensor elements 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
- Strengthening of weak sensor signals directly on site
- Transmit standardized signals
- Protect against electromagnetic interspersion
- Option to conduct measuring point diagnostics
The resistance thermometer is intended for installation in containers and pipelines for hygienic requirements. - Modular design consisting of protective pipe, measuring insert, connection head and optional transmitter for replacement during operation.
- Hygienic version, design according to recommendations of the EHEDG
- Transmitter can be integrated (4 to 20 mA, PROFIBUS PA or FOUNDATION Fieldbus)
