pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. Pressure Sensor can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal (such as 4~20mADC, etc.), to supply secondary instruments such as indicating alarms, recorders, regulators, etc. for measurement and indication and process regulation.
Pressure transmitters are used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.
There are two types of pressure transmitters: electric and pneumatic. The uniform output signal of the electric type is a direct current signal such as 0-10mA, 4-20mA or 1-5V. The unified output signal of the pneumatic type is the gas pressure of 20-100Pa.
Pressure transmitters can be divided into force (torque) balance type, capacitive type, inductive type, strain type and frequency type according to different conversion principles.
Our advantageous products are mainly compact pressure transmitters, pressure transmitters with display, differential pressure transmitters, wind pressure transmitters, etc.
The main advantage
1. The pressure transmitter has the characteristics of reliable operation and stable performance
2. Dedicated V/I integrated circuit, less peripheral components, high reliability, simple and easy maintenance, small size, light weight, and extremely convenient installation and debugging;
3. Aluminum alloy die-casting shell, three-terminal isolation, electrostatic spray protection layer, durable;
4. 4-20mA DC two-wire signal transmission, strong anti-interference ability and long transmission distance;
5. LED, LCD, and pointer three kinds of indicator heads, the on-site reading is very convenient. Can be used to measure viscous, crystalline and corrosive media;
6. High accuracy and high stability. In addition to the imported original sensor that has been corrected by laser, the comprehensive temperature drift and nonlinearity of the whole machine within the operating temperature range are finely compensated.

The sense of the future high-speed air pressure train speeds up to 6400 kilometers per hour
The idea of an air pressure-driven train isn’t entirely novel. A century ago, similar concepts were proposed, with the pioneering American rocket scientist Robert Goddard suggesting something along these lines. Even in popular culture, such as the iconic sci-fi series *Star Trek*, you’ll find echoes of this futuristic concept.
Recently, an American designer named Darryl Oystermade headlines with a revolutionary ultra-high-speed train concept capable of traveling from New York to London in under an hour. That’s a distance of approximately 4,000 miles, or 6,400 kilometers. Dubbed the "Vactrain," this cylindrical vehicle operates within an airtight pipeline. By evacuating all the air in front of the train, the pressure difference between the rear and front creates a powerful propulsion system, driving the train forward at incredible speeds.
Oystermade's company, ET3, has already sold licenses for 60 six-passenger versions of the vacuum tube transport system. Despite this initial success, Oyster believes the full potential of this technology—both in terms of speed and scalability—has yet to be realized. He envisions the Vactrain as a game-changer for interconnecting dispersed urban centers, even allowing underwater routes at carefully planned depths. Oyster claims his design could outperform today’s high-speed rail systems while costing significantly less and consuming far less energy per kilometer. He predicts this technology could become operational within a decade.
While the concept is exciting, there’s still plenty of work to be done before it becomes a practical reality. Engineering challenges like maintaining structural integrity in pressurized tubes and ensuring passenger comfort at such high speeds need addressing. Still, the promise of revolutionizing transportation is hard to ignore. Imagine a world where transatlantic travel takes less time than a typical commute!
This isn’t just a dream—it’s a glimpse into what might soon become our future. And while it may take some time before we see these trains zipping across continents, the groundwork is being laid today. Who knows? Maybe by the end of the decade, we'll be boarding a Vactrain for our next big adventure.
