Scalable 4–20 mA output
Send process temperature directly to a PLC analogue input while retaining digital setup through IO-Link.

ifm TA Temperature Transmitters
Compact industrial temperature transmitters with an integrated RTD probe, scalable 4–20 mA output and IO-Link. TA is a strong route when the machine needs a robust transmitter rather than a local display or switching interface.

Compact transmitter
TA for a transmitter signal without local display
The TA family integrates probe, electronics and process connection into a compact stainless-steel architecture.
02
Low-mass sensing-tip design
The thin-film RTD construction reduces thermal mass for repeatable, fast process response.
03
One-piece transmitter design
Integrated process connections and multiple insertion lengths simplify machine integration.
04
IO-Link parameterisation
Scale the analogue range, access status and commission the transmitter digitally.
Typical industrial use
Temperature measurement for machine fluids and equipment protection
01
Hydraulic oil temperature
Track fluid temperature to protect pumps, seals and process stability.
02
Cooling-water and coolant circuits
Monitor machine cooling performance and detect overheating conditions.
03
Industrial tanks and pipelines
Use an integrated probe/transmitter where a 4–20 mA temperature signal is preferred.
RTD technology
Thin-film RTD construction improves response while keeping the transmitter compact
ifm positions TA around a Pt1000 Class A sensing element and low-mass tip design. The sensor and electronics are matched and factory calibrated to provide a stable transmitter signal.

ResponseCurrent industrial guidance highlights T05/T09 around 1/3 s on key variants.
Mechanical designStainless-steel probe with integrated process connection or stick-probe route.
StatusLED indication gives quick operating-state feedback without adding a local numeric display.
Beyond 4–20 mA
IO-Link keeps the analogue transmitter configurable and transparent
Use the analogue output for the control system while IO-Link provides digital commissioning and access to device data.
01
Scale the analogue range
Configure the 4 mA and 20 mA temperature points without manual trimming.
02
Read temperature digitally
Digital values avoid extra A/D conversion where the system uses IO-Link directly.
03
Device information and replacement
Centralised parameters support documented commissioning and faster device replacement workflows.

Temperature-family choice
TA or another ifm temperature family?
| Requirement | Best route to review | Why |
|---|---|---|
| Compact 4–20 mA transmitter, no local display | TA | Primary fit Integrated transmitter + IO-Link |
| Local display + switching / analogue functions | TN | Better operator visibility and local setup |
| Sanitary display transmitter | TD | Hygienic integrated route |
| Calibration-check requirement | TCC | Dual-element self-monitoring architecture |
| Very high temperatures / modular RTD | TR / TW | Review the wider ifm temperature portfolio |
Industrial and sanitary TA variants are not identical. Keep process connections, temperature ranges, hygienic approvals and response data tied to the actual product route.
