## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What makes these temperature sensors suitable for sterilization equipment?
**A**: These sensors feature stainless steel housings for durability in harsh environments and platinum RTD elements that provide exceptional accuracy (±0.1°C) required for precise sterilization process control.

### Q: How do I choose between RTD and thermocouple options for my machinery?
**A**: RTD sensors with platinum elements offer higher accuracy and stability for critical sterilization processes, while nickel-chromium thermocouples provide wider temperature ranges and faster response times for less critical applications.

### Q: What maintenance is required for these industrial temperature sensors?
**A**: Minimal maintenance is needed beyond periodic calibration checks. The stainless steel housing resists corrosion, and the sealed connection head protects internal components from moisture and contaminants in manufacturing environments.
