Product Description

It usually refers to a vacuum pressure transmitter, a precision instrument specifically designed for measuring vacuum degree (negative pressure) or absolute pressure.

What is the relationship between vacuum transmitters, gauge pressure and 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.

Application scenarios

Industrial process control: It is used to monitor the absolute pressure of equipment such as degassing systems, distillation towers, evaporators, and crystallizers. It also monitors the vacuum degree in vacuum drying and vacuum forming processes.
Semiconductor and electronic manufacturing: It is used in core vacuum equipment such as photolithography machines, evaporation chambers, and cleaning devices to monitor pressure fluctuations in real time, ensuring process stability and product yield.
Aerospace: It is used to monitor the pressure inside aircraft cabins to ensure the safety of equipment and personnel in low-pressure environments at high altitudes.
Medical equipment: It is used in devices such as aspirators, infusion pumps, and extracorporeal circulation systems to monitor vacuum or pressure, ensuring the safe operation of the equipment.
Scientific research and leak detection: It is used in laboratory vacuum systems, high vacuum or ultra-high vacuum measurements, and equipment leak detection.

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.
