Key Features:
- Multi-Type Flexibility – Auto-scales for 9 thermocouple types without jumpers.
- Noise Immunity – 150dB common-mode rejection at 50/60 Hz.
- Lead Resistance Compensation – Eliminates error from long wiring runs.
- Diagnostic Alarms – Reports sensor break, out-of-range, calibration faults.
- Hot-Swap Capable – Replace without system shutdown (RX3i backplane).
- Rack-Optimized – Compact 2-slot width (saves panel space).
Primary Function & Purpose:
Converts low-voltage thermocouple outputs into precise digital temperature data for:
- Real-time monitoring of critical assets (motors, bearings, reactors).
- Over-temperature safety shutdowns (SIL 2 certified logic).
- Predictive maintenance via thermal trend analysis.
Typical Applications:
- Turbine Monitoring – Bearing/oil temperature in gas/steam turbines.
- Industrial Furnaces – Kiln, oven, and heat treatment zone control.
- Power Transformers – Winding temperature protection.
- Chemical Reactors – Exothermic reaction thermal management.
- HVAC Systems – Duct/boiler temperature feedback.
Application Fields:
Deployed in high-precision thermal control systems across:
- Energy: Fossil/nuclear power plants, wind turbine gearboxes.
- Manufacturing: Metal smelting, glass production, plastic extrusion.
- Oil & Gas: Refinery distillation columns, pipeline heaters.
- Pharmaceutical: Sterilization autoclaves, bioreactor monitoring.
