### **Cons**
1. **Limited Digital Functionality**
- **No data logging or remote monitoring** capabilities. Unlike smart gauges, this model cannot transmit data wirelessly or store historical readings.
- Requires manual reading, which may not be practical in automated systems.
2. **Susceptibility to Mechanical Damage**
- The bourdon tube and moving parts can be **damaged by excessive vibration, shock, or improper installation**, leading to inaccurate readings or failure.
- Improper handling during installation or maintenance can cause misalignment or breakage.
3. **No Built-In Overload Protection**
