6. Selection Recommendations
Sensor Compatibility: Verify RTD type (e.g., PT100 vs. PT1000) and wire configuration.
Environmental Conditions: Choose modules with EMI shielding for noisy environments.
Redundancy: Pair with dual RTD sensors for critical temperature measurements.
7. Installation & Maintenance
Wiring: Use twisted-pair cables with proper termination resistors for 3/4-wire RTDs.
Calibration: Perform biannual checks using GE’s calibration tools.
Firmware Updates: Regularly update firmware to ensure compatibility with control system upgrades.
