NI USB-TC01 (Device Only) — 1-Channel Temperature Input Device
Short overview (long-tail friendly):
The NI USB-TC01, 781314-01 is a compact single-channel USB thermocouple interface for
J, K, T, E, N, R, S, B types with integrated cold-junction compensation (CJC),
20-bit resolution, and a software-timed sample rate up to 4 S/s. Designed for
slow / low-frequency temperature logging, bench R&D trending, and single-probe monitoring on a PC via USB.
This module is part of the broader family of
Data Acquisition and Control Systems
used in laboratory automation, testing, and industrial monitoring. It also belongs to
Test and Measurement Equipment
commonly applied in temperature calibration, validation, and prototype diagnostics.
Key use cases
- USB K-type/J-type single-probe temperature monitoring
- Slow process warm-up/cool-down trend logging (≤ 1 Hz bandwidth)
- Benchtop fixtures, environmental chambers, calibration rigs
- Ad-hoc measurements in labs and service workflows
Highlights
- Integrated CJC & open-thermocouple detection
- 20-bit ADC resolution for stable low-frequency reads
- USB 2.0 (bus-powered); plug-and-log with NI software
- Supports J, K, T, E, N, R, S, B thermocouples
