Description
The 56-TR-55I-PT is TandD’s compact logger for Pt sensors — connect Pt100 or Pt1000 in 3- or 4-wire configuration via the included input module, and cover temperatures from -199 to +600 °C with high-precision measurement. Pt sensors offer better accuracy and stability over time compared to thermistors, making it the choice for calibration tasks and industrial precision measurements.
NOTE: Pt sensors are NOT included — ordered separately according to application (rod dimension, cable length, IP class). Optical data transfer via 56-TR-50U2 USB holder (sold separately).
Features
- 1 channel Pt100 or Pt1000 (3- or 4-wire)
