Support universal sensor inputs
Connect RTDs, thermocouples, resistors, potentiometers and millivolt sources for flexible temperature measurement across the plant.
Why SITRANS TF320/420?
SITRANS TF320/420 are rugged, field‑mounted temperature transmitters that ensure accurate, continuous measurement in harsh conditions. Universal inputs, easy configuration and robust diagnostics keep processes stable and safe.
Portfolio:
- SITRANS TF320 — 4–20 mA with HART 7, universal input
- SITRANS TF420 — dual inputs with hot backup, HART 7, SIL2/3 for safety‑critical use
Key benefits
Maximize uptime
Hot backup in TF420 switches seamlessly to a second sensor so measurements continue without data loss during a failure.
Improve plant safety
SIL2/3 certification and broad Ex approvals make TF420 suitable for safety‑critical applications and extreme environments down to −50 °C.
Simplify configuration
Set up quickly via SIMATIC PDM, handheld communicator, or the local display with push buttons for fast commissioning.
