---

### **Cons**

1. **Higher Upfront Cost Compared to Basic Sensors**

- More expensive than basic mechanical gauges or simple electronic sensors, especially in higher accuracy or hazardous area-rated versions.

- Additional costs may arise from mounting hardware, calibration, or installation labor.

2. **Limited Digital Communication in Basic Models**

- The **2990019** is primarily a **4-20 mA analog device**, meaning it lacks built-in digital protocols (e.g., HART, Profibus) unless specified in a higher-end variant.

- Requires additional converters or gateways if digital integration is needed.

3. **Potential for Signal Drift Over Time**

- Like all analog sensors, it may experience **slow drift** due to environmental factors (temperature, vibration, or chemical exposure), requiring periodic recalibration.

- High-precision applications may require more frequent maintenance.

4. **Sensitivity to Installation Conditions**

- Improper mounting (e.g., incorrect orientation, excessive vibration) can affect accuracy.

- Requires proper **piping and isolation** to prevent damage from upstream pressure surges or contamination.

5. **Limited Range of Pressure Types (Without Upgrades)**

- Some variants may not support **differential pressure** or **high-temperature steam** without additional sensors or accessories.

- Specialized applications (e.g., cryogenic systems) may require custom configurations.

6. **Dependence on Power Supply**

- Requires a **24V DC power source** (or other specified voltage) for operation, which must be stable to avoid signal fluctuations.

- Failure of the power supply can lead to loss of signal.

7. **Potential for Condensation in Wet Environments**

- If exposed to moisture or humidity, condensation inside the sensor housing can affect performance unless properly sealed or heated.

- Requires **drainage or heating elements** in humid or corrosive atmospheres.

8. **Calibration Complexity for Non-Experts**

- While calibration is built-in, improper handling can lead to errors. Trained personnel may be needed for accurate setup.

- Some advanced calibration features may require specialized tools or software.

9. **Weight and Bulk in Heavy-Duty Versions**

- Higher-pressure or hazardous-rated models can be **heavy and bulky**, making installation in space-constrained systems challenging.
