Recommendation
SeaDeal helps choose transmitters or sensors by output, process connection, environment, display and control-system requirements.
Comparison table
| Criteria | Recommended option | Alternative option |
|---|---|---|
| Signal output | Pressure transmitter: 4-20 mA, HART or digital outputs. | Pressure sensor: raw or lower-level signal depending on design. |
| Industrial use | Better for process plants and field installation. | Often used inside equipment or compact systems. |
| Selection focus | Range, accuracy, connection, material and output. | Size, signal and OEM integration. |
Application scenarios
Buyers often use sensor and transmitter interchangeably, but output signal, packaging, calibration and industrial robustness are different.

Frequently asked questions
What is the difference between pressure transmitter and pressure sensor?
A transmitter usually provides a conditioned industrial signal, while a sensor may provide a raw or equipment-level signal.
Which one should I use for PLC control?
Use an industrial pressure transmitter with 4-20 mA or the signal required by the PLC.
