- **Differential pressure versions** may have **lower accuracy** compared to dedicated differential pressure transmitters.

2. **Higher Upfront Cost Compared to Analog Sensors**

- Digital transmitters with **HART/fieldbus** are **more expensive** than basic **4 20 mA analog sensors**.

- Requires **compatible master devices** (e.g., HART communicators, fieldbus networks), adding to system costs.

3. **Complexity in Integration**

- **Not plug-and-play** requires **proper wiring, power supply, and communication setup** (e.g., HART router for analog digital signals).

- **Training needed** for technicians to configure and troubleshoot digital communication protocols.

4. **Potential for Signal Interference**

- **HART communication** can be susceptible to **electromagnetic interference (EMI)**, requiring **shielded wiring** in noisy environments.

- **Fieldbus networks** may experience **latency or communication errors** if not properly maintained.

5. **Limited Customization for Extreme Conditions**
