Working Principle:
The case expansion monitor receives signals from proximity probes or LVDT sensors mounted on the machine casing to measure thermal growth. As the machine heats up during operation, the casing expands thermally. The sensors detect this expansion as a change in displacement, which the monitor converts to a proportional 20 mA current output. The monitor continuously compares the measured expansion against configured alarm thresholds, triggering alarms when thermal growth exceeds safe limits.
Installation Requirements:
- Mount module in standard 3300 series rack or panel
- Connect thermal growth sensors to appropriate input channels
- Configure expansion range and alarm setpoints per machine specifications
- Connect 20 mA current outputs to DCS/PLC for thermal growth indication
- Connect relay outputs to alarm/trip logic circuits
- Configure remote monitoring interface if required
- Verify power supply is stable and within tolerance
Usage Notes:
- Ensure sensor mounting provides accurate thermal growth measurement
- Configure alarm thresholds based on machine manufacturer recommendations
- Test alarm functions during commissioning
- Monitor web-based interface for real-time thermal growth trends
- Perform periodic calibration of thermal growth sensors
- Verify communication links for remote monitoring functionality
