2638A-101

Overview

The Fluke 2638A-101 is a set of current shunt resistors designed for the Hydra Series III 2638A data acquisition system. Each resistor has a nominal resistance of 10 Ohms with an accuracy of ±0.08%. The set contains ten units, enabling measurement of up to ten current channels simultaneously. These components support current measurements up to 100 mA by converting flowing current into a proportional voltage drop across the resistor, which the instrument processes for display and recording.

Feature Summary

• Provides precise current-to-voltage conversion for low-current applications
• Compatible with universal input modules for easy installation
• Ensures accurate data logging for multiple simultaneous channels

Applications

• Low-current circuit monitoring in industrial data acquisition systems
• Precision current measurement in laboratory environments using Hydra Series III
• Multi-channel current logging where direct current sensors are not feasible

Procurement Notes

Verify compatibility with the Fluke 2638A Hydra Series III data acquisition system before purchase. Ensure the application requires current measurements within the 100 mA limit. Confirm that the universal input module is available for mounting these shunts. Check for any specific firmware requirements if integrating with legacy software versions.

Selection Notes

Select this component when high-accuracy current measurement is required for signals up to 100 mA. It is suitable for applications needing multiple isolated current channels without external transducers. Consider the ±0.08% accuracy for critical calibration tasks. Ensure the total number of channels does not exceed the ten provided in the set.

Part Context

This part is an accessory for the Fluke 2638A data acquisition system, part of the Hydra Series III family. It complements the main unit's ability to measure various electrical parameters. Unlike general-purpose shunts, these are optimized for the specific input architecture of the 2638A, ensuring seamless integration and accurate scaling within the device's software environment.

Replacement Considerations

For Hydra Series III systems, use only the 2638A-101 shunt set. Legacy Hydra or Hydra Series II products require the 2620A-101 due to different lead spacing. Do not substitute with generic 10 Ohm resistors as they lack the specified accuracy and mounting compatibility.
