- Resolution: 0.1°C Material Composition:
- Front panel: Aluminum alloy surface oxidation treatment
- Main circuit board: High‑grade FR‑4 fire‑retardant printed circuit board
- Backplane connector: Gold‑plated industrial grade male‑female connector for rack bus connection
- Metal shielding shell: Cold‑rolled steel anti‑interference shielding housing Structural Characteristics:
- Standard 3500 rack plug‑in structure, double‑slot width form factor
- Front panel equipped with status indicator LED lamps: OK, Alarm, Bypass, Fault
- Rear side connects to 3500 rack backplane bus, matched with isolated I/O assembly 133835‑01
- Mechanical locking screws on both sides for firm fixing inside instrument rack Working Principle: It receives weak analog signals output from field RTD or thermocouple sensors. Internal circuit implements signal filtering, amplification and analog‑to‑digital conversion. The microcontroller unit compares real‑time measured temperature value with pre‑programmed high‑alarm and danger‑alarm setpoints. When measurement exceeds threshold, it sends alarm instruction to 3500 series relay modules, meanwhile transmits temperature data to system backplane for host software reading and trend recording. Installation Requirements:
- Install into standard Bently Nevada 3500 instrument rack, occupy two adjacent slots
- Complete rack power‑off before inserting or removing this module; this module is not hot‑swappable
- Field sensor wiring must adopt shielded twisted‑pair cable, shield layer single‑end grounding at cabinet side
- Isolated thermocouple I/O assembly 133835‑01 must be matched for signal termination
- Maintain 20mm minimum ventilation gap around module for heat dissipation
- Strictly follow API 670 installation specification for field sensor wiring layout Usage Notes:
- Each channel shall be configured to match actual connected sensor type via official 3500 configuration software
- Do not mix RTD and thermocouple signal wiring inside one terminal group
- Regularly inspect terminal tightness to avoid bad contact caused by vibration
- Avoid installing this module in locations with heavy dust, corrosive gas and continuous strong vibration
- Calibrate whole temperature measurement loop at least once per year
