1 Siemen AG 00 Temperature Meaurement Overview Application Linearized temperature meaurement with reitance thermometer or thermal element Differential, mean-value or redundant temperature meaurement with reitance thermometer or thermal element Linear reitance and bipolar millivolt meaurement Differential, mean-value or redundant reitance and bipolar millivolt meaurement Verion: For FOUNDATION fieldbu For PROFIBUS PA The temperature tranmitter i a mall field bu tranmitter for mounting in the connection head of form B. Extenive functionality enable the temperature tranmitter to be preciely adapted to the plant requirement. Operation i very imple in pite of the numerou etting option. Thank to it univeral concept it can be ued in all indutrie and i eay to integrate in the context of Totally Integrated Automation application. Tranmitter of the "intrinically afe" type of protection can be intalled within potentially exploive atmophere. The device comply with the Directive 94/9/EC (ATEX), a well a FM and CSA regulation. Intalling in temperature enor turn them into complete, bu-capable meauring point; compact - and in a ingle device. Function Feature General Mounting in connection head, type B, to DIN 479, or larger Polarity-neutral bu connection 4-bit analog-digital converter for high reolution Electrically iolated Intrinically-afe verion for ue in potentially exploive area Special characteritic Senor redundance with PROFIBUS PA communication Function block: x analog with FOUNDATION fieldbu communication Function block: x analog and x PID Functionality: Baic or LAS Mode of operation The following function diagram explain the mode of operation of the tranmitter. The only difference between the two verion of the SITRANS TH400 (7NG4-... and 7NG5-...) i the type of fieldbu protocol ued (PROFIBUS PA or FOUNDATION fieldbu).
