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.

Experimental Study on Dry Grinding of Titanium Alloy by Single-layer Self-lubricating Brazing CBN Grinding Wheel
In this superhard material technology development forum, Wu Jie of the College of Mechanical and Electrical Engineering of Nanjing University of Aeronautics and Astronautics made a technical report on "Experimental Research on Dry Grinding of Titanium Alloy by Single-layer Self-lubricating Brazing CBN Grinding Wheel". Abstract of the paper: Since the industrial production of titanium alloy in 1948, it has many advantages such as light weight, high strength, high and low temperature performance, strong corrosion resistance, etc., and therefore in the aerospace industry, biomedicine, and chemical and petroleum. In the industry, it has been rapidly promoted and applied, but because of the low thermal conductivity and the like, it is prone to burns during grinding and affects the surface quality of the workpiece. Therefore, the traditional grinding process uses a large amount of grinding fluid to reduce the grinding. Temperature, but the extensive use of grinding fluids poses a significant hazard to the environment and operator health, and increases the cost of grinding fluid discharge recycling. In order to solve the above problems, this paper developed a single-layer self-lubricating brazed cubic boron nitride (cBN) grinding wheel based on the idea of ​​“replacement of grinding fluid with solid lubricantâ€. The basic principle is to apply a solid lubricant to the surface of the grinding wheel, so that the lubricant forms a lubricating film between the abrasive particles and the workpiece, thereby reducing the friction coefficient between the abrasive particles and the surface of the workpiece, reducing friction, and reducing the grinding. The purpose of heat removal is to reduce the grinding temperature. In this paper, graphite is selected as a solid lubricating thorn. It is applied to the surface of brazed cBN grinding wheel by a suitable process to carry out the experimental research on grinding the titanium alloy workpiece. The grinding temperature of the titanium alloy processed by the grinding wheel under different cooling conditions is compared and analyzed. Exploring an effective method to improve the performance of dry-grinding titanium alloy by single-layer self-lubricating brazing cBN grinding wheel. The above text is selected from the "Experimental Study on Dry-grinding Titanium Alloy by Single-layer Self-lubricating Brazing CBN Grinding Wheel", which is included in the "2012 China Superhard Materials Technology Development Forum Proceedings".
