Selection Suggestions and Precautions

Selection Suggestions

  • Choose GE 8101-HI-TX-02 for GE PAC8000-based systems requiring HART-enabled analog input and high-precision signal acquisition.
  • Opt for it in petrochemical, power, or metallurgical applications where line fault detection and fast response times are critical.

Precautions

  • Ensure the 24V DC field power supply is stable to maintain GE 8101-HI-TX-02’s measurement accuracy and fault detection reliability.
  • Verify HART transmitter compatibility before integration, as GE 8101-HI-TX-02 supports HART pass-through (not native HART control).
  • Check wiring continuity and avoid overloading channels to prevent false fault alarms from GE 8101-HI-TX-02.
  • Use GE’s dedicated configuration software to calibrate GE 8101-HI-TX-02 and set fault detection thresholds per application requirements.
  • Avoid exposing GE 8101-HI-TX-02 to extreme moisture or corrosive environments, as this may degrade its isolation and measurement performance.
