Description

Key Advantages of the NI-9213 C-Series Thermocouple Input Module

• Highest single-module channel density (16 channels)
• Lowest cost per channel
• Flexible spring terminal connections
• Built-in automatic zeroing and cold junction compensation

The NI-9213 is positioned as a high-density solution within NI's C-series thermocouple module product line

Measurement Sensitivity

The NI-9213 is available in two connector versions:

• Standard spring terminals
• Push-in spring terminal

Connection Features and Advantages:

• No soldering required, quick wiring
• Supports single-strand and multi-strand wires (with cold-press head)
• Push-in version supports tool-free wiring

Environmental Adaptability

The NI-9213 C-Series Thermocouple Input Module is designed to address the three major pain points of high-channel-count temperature measurement systems:

• If you need to solve too many slots occupied: NI-9213 designed the 16-channel high-density design, 128 channels can be provided with 8 modules
• If you need to solve Insufficient measurement accuracy: This module designed 24-bit ADC + Automatic Zeroing + CJC Triple Protection
• If you need to solve the system complexity is too high: This module designed Integrated anti-aliasing filter simplifies system

Application:

✅Automobile- Vehicle thermal management test, engine temperature rise test, climate chamber test

✅Aerospace- Aircraft thermodynamic testing and engine compartment temperature monitoring

✅Energy- Battery pack temperature monitoring and photovoltaic panel testing

✅Industry- Furnace temperature monitoring and heat treatment process control

✅Research- Material thermal performance testing and environmental chamber temperature recording

✅Semiconductor- Wafer processing temperature

NI-9213 Vs NI-9211: 4x channel density, suitable for large-scale temperature monitoring. Vs NI-9214: Higher sampling rate, lower price. Vs competitors: NI brand guarantee + LabVIEW ecosystem support.

The auto-zero channel is a dedicated internal channel built into the NI-9213 C-Series Thermocouple Input Module for measuring and compensating for system offset errors. Measurement accuracy can be significantly improved by subtracting the auto-zero value from each thermocouple reading.

Accuracy Improvement:

• Offset Error in High-Resolution Mode: 4 µV (Typical) / 6 µV (Maximum)
• Offset error is further reduced after enabling auto-zeroing

Dual timing mode

• High-resolution mode: Conversion time: 55 ms/channel. Sampling rate: 1 S/s (all channels). Features: Highest accuracy, 50/60Hz noise suppression (60 dB).
• High-speed mode: Conversion time: 740 µs/channel. Sampling rate: 75 S/s (all channels). Features: High sampling rate, wide signal bandwidth (78 Hz)

The NI-9213 has a built-in hardware anti-aliasing filter that follows the Nyquist sampling theorem to ensure no frequency aliasing at the sampling frequency.

Notes:

​​​​​​​To achieve optimal measurement accuracy, please follow these guidelines:

✅Use small-gauge thermocouple wires: Reduce heat transfer to/from the terminal junction

✅Avoid proximity to heat/cold sources: Keep thermocouple wires away from hot or cold objects

✅Mize adjacent heat sources and airflow: Minimize heat sources and airflow near the terminals

✅Maintain stable ambient temperature: Avoid drastic temperature fluctuations

✅Module orientation: Ensure the NI-9213 terminals are facing forward or upward

✅Maintain stable orientation: Do not frequently change the module orientation

✅Wait for thermal equilibrium: Wait for the thermal gradient to stabilize after system power changes

✅Bundle wiring: Bundle thermocouple wires near the spring terminal connector

✅Use extension wires of the same material: If extension wires are required, use wires of the same material as the thermocouples

✅Use the NI-9940 back cover kit: Protect connections in high-vibration applications
