It usually refers to a vacuum pressure transmitter, a precision instrument specifically designed for measuring vacuum degree (negative pressure) or absolute pressure.
| Instrument Type | Core Measurement Principle | Role in Vacuum Measurement |
|---|---|---|
| Gauge Pressure Transmitter | Refers to atmospheric pressure as the reference zero point and can measure both positive and negative pressure. | Can be used to measure rough vacuum. For example, a transmitter with a range of -0.1 MPa to 0 MPa, when it outputs 4 mA, it indicates a vacuum degree of -0.1 MPa. |
| Absolute Pressure Transmitter | Refers to absolute vacuum as the reference zero point, and the measured value is always positive. | Is an ideal choice for measuring medium and high vacuum. Because it is based on vacuum, the reading is not affected by fluctuations in atmospheric pressure and can truly reflect the absolute pressure inside the container. |
| Vacuum Transmitter | As an application category, it can adopt either gauge pressure measurement principle (such as measuring -100 kPa to 0 kPa) or absolute pressure measurement principle (such as measuring 0 to 100 kPa absolute pressure). | Essentially, it is a transmitter designed and optimized for vacuum application scenarios. |
Vacuum pressure transmitters are indispensable precision measurement tools in industrial automation. Their core value lies in measuring based on absolute vacuum, thereby completely eliminating the influence of atmospheric pressure changes.
