Temperature Measurement Transmitters for field mounting

Transcription

1 Siemens AG 07 Overview Application The SITRANS TF can be used everywhere where temperatures need to be measured under particularly harsh conditions. For that reasons users from all industries have opted for this field device. The rugged enclosure protects the electronics. The stainless steel model is almost completely resistant to sea water and other aggressive elements. The inner workings offer high measuring accuracy, universal input and a wide range of diagnostic options. Our field devices for heavy industrial use FOUNDATION fieldbus PROFIBUS PA The SITRANS TF temperature transmitter works where others can t cope. Benefits For universal use as a transmitter for resistance thermometers, thermocouple elements, or mv signals Rugged two-chamber enclosure in die-cast aluminium or stainless steel Degree of protection IP66/67/68 Can be mounted elsewhere if the measuring point - is hard to access, - is subject to high temperatures, - is subject to vibrations from the system, - or if you want to avoid long neck tubes and/or protective tubes. Can be mounted directly on American-design sensors Wide range of approvals for use in potentially explosive atmospheres. "Intrinsically safe, non-sparking and flameproof" type of protection, for Europe and USA Function Features Polarity-neutral bus connection 4-bit analog-digital converter for high resolution Electrically isolated Version for use in hazardous areas Special characteristic Sensor redundance Transmitter with PROFIBUS PA communication Function blocks: x analog Transmitter with FOUNDATION fieldbus communication Function blocks: x analog and x PID Functionality: Basic or LAS Mode of operation The following function diagram explains the mode of operation of the transmitter. The only difference between the two versions of the SITRANS TF (7NG and 7NG ) is the type of field bus protocol used (PROFIBUS PA or FOUNDATION fieldbus). Optional inputs: - Resistance thermometer - Thermocouple - mv sensor - Resistance-based sensors Transformer Input Input Differential Mean value Redundancy Terminal temperature Engineering units Diagnostic functions Table linearization Polynomial linearization Process calibration 6 Electrically isolated Input Input A/D converter CPU Communication Ex power circuit Bus connection Internal Pt00 EEPROM Complex configuration Correction coefficient Factory settings - PROFIBUS PA protocol (7NG337) or - FOUNDATION Fieldbus protocol (7NG338) SITRANS TF with TH400, function diagram /78 Siemens FI 0 07
