The TD2531 is a 100 mm installation-length temperature transmitter designed for accurate process temperature monitoring. It incorporates a Pt1000 Class A sensing element and an integrated four-digit LED display. The transmitter supports both conventional 4–20 mA control-system integration and IO-Link digital communication. Its extended 100 mm probe provides deeper penetration into tanks, pipes, and process vessels. The hygienic stainless-steel construction makes it suitable for demanding industrial and sanitary applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
TD2531 is designed for reliable temperature measurement in process automation. The 100 mm installation length provides increased sensing depth compared with compact 50 mm models. Local display indication allows quick process verification. IO-Link provides additional configuration and diagnostic capabilities. The transmitter is suitable for continuous temperature monitoring.
The Pt1000 element provides repeatable temperature measurement. The device supports a -50...150 °C measuring range. Its analogue output is available as a standard 4–20 mA signal. IO-Link allows digital process-value communication and parameterisation. The 1/3 second T05/T09 dynamic response supports responsive process monitoring.
The 100 mm probe is suitable for deeper process measurement points. The G 1/2 sealing-cone connection supports straightforward mechanical installation. The stainless-steel construction provides good resistance to process and cleaning conditions. The M12 electrical connection supports industrial wiring practices. The device can be integrated into PLC, SCADA, and process-control systems.
IO-Link provides useful device-level information for maintenance teams. The local display helps technicians confirm operation during commissioning. Electrical protection improves reliability in industrial installations. Routine maintenance can include inspection of the process connection and sensor installation. Correct positioning helps ensure stable and representative temperature measurement.
