Where TF02-EX fits in the installed system
Use the complete TF02-EX designation when tracing a fault or buying a replacement. TF02-EX is a head-mounted fieldbus temperature transmitter and its installed duty matters more than a visually similar housing.
Technical data to check first
| Technical item | Verified value / selection note |
|---|---|
| Complete designation | TF02-EX |
| Product family | TF02-EX |
| Component role | head-mounted fieldbus temperature transmitter |
| Function | Temperature transmitter |
| Protocol | FOUNDATION Fieldbus |
| Mounting | Sensor head |
| Variant | Ex version; check approval and nameplate |
| Final configuration | Confirm exact nameplate, hardware revision and order options before purchase |
The TF02-EX values above identify this selection. Verify the actual nameplate, hardware revision and option set before declaring another code equivalent.
Observed fault and process consequence
In this installation, TF02-EX is intended to convert the installed temperature sensor signal to the fieldbus process variable. Write down the fault indication, operating state and last known good reading before removal.
If TF02-EX trips or loses communication intermittently, separate wiring and supply faults from device faults. Capture the relevant alarm history and field measurements.
Acceptance evidence
The practical test for TF02-EX is to compare indicated temperature with a traceable input and confirm bus diagnostics. Log the expected result, actual result, date and responsible technician.
Do not close a TF02-EX replacement ticket on visual inspection alone. Confirm the normal function and the planned failure or alarm response where safely testable.
Replacement compatibility review
For TF02-EX, compare sensor type, hazardous-area approval, segment power, wiring, function block and mounting head. Check the complete order code, not only the family prefix.
A proposed substitute for TF02-EX requires a documented comparison of electrical or process rating, terminals, communications, mechanical fit and any required settings.
Installation handover
Isolate the circuit or process before touching TF02-EX; follow the site's approved safety procedure. Record cable labels, settings, accessory positions and original markings.
When TF02-EX is fitted, restore the approved configuration and make sure installation details match the drawings. Keep removed parts until the acceptance result is signed off.

Records to keep
File the TF02-EX order identification, inspection result, settings backup and commissioning evidence with the equipment record.
If TF02-EX is later reordered, compare the current installation record with the supplier's complete designation before the purchase is released.
