Below is its comprehensive detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Basic Identification	- Model: 3500/65 145988-02- Product Type: 8-Channel High-Precision Temperature Monitor- Applicable System: Bently 3500/10 single-frame racks, 3500/20 multi-frame racks- Channel Quantity: 8 independent, electrically isolated temperature monitoring channels (avoids cross-interference between channels)
Temperature Measurement Performance	- Measurement Range: -200°C to +800°C (supports both low-temperature bearings and high-temperature stators/pipelines)- Accuracy:- ±0.05°C (at -50°C to +150°C, optimal for RTD-based bearing monitoring)- ±0.1°C (at +150°C to +400°C)- ±0.3°C (at -200°C to -50°C or +400°C to +800°C, suitable for thermocouple-based high-temperature measurement)- Resolution: 0.001°C (enables detection of micro temperature changes, e.g., gradual bearing heating)- Update Rate: 0.5 seconds per channel (faster than standard 3500/60 modules, ideal for dynamic temperature tracking)
Sensor Compatibility	- RTD Support: 2-wire/3-wire/4-wire Pt100 (Class A/B), Pt1000, Cu50, Cu100; automatic wire resistance compensation for 3-wire/4-wire configurations (eliminates errors from long sensor cables, up to 100m)- Thermocouple (TC) Support: Type E, J, K, T, R, S, B, N; built-in high-precision cold-junction compensation (CJC) with accuracy ±0.08°C (uses a dedicated internal temperature sensor to correct ambient temperature fluctuations)- Input Impedance: ≥100 MΩ (for TC inputs, minimizes signal attenuation); ≤0.05Ω (for RTD current loops, ensures stable 1mA/2mA excitation current)
