Feejoy Technology (ShangHai) Co., Ltd.

Best Quality Pressure Transmitter Manufacturer

FEEJOY pressure transmitter is a sensor for measuring the pressure of liquid and gas. Similar to other different pressure transmitters, the pressure sensor can convert pressure into pneumatic or electric signal for when it works. Our pressure transmitter can convert physical pressure parameters like gas and liquid sensed by the load cell sensor into standard electrical signals (such as 4 ~ 20mADC, etc.) to provide secondary instruments like indicating alarms, recorders, regulators for measurement and indication. And process regulation. 

As a pressure transmitter manufacturer, our engineering team uses the latest reliable sensing technology and apply our quality principles to manufacture economical pressure transmitter products, which can even overcome the foremost trivial industrial application problems.

Pressure transmitter indicators are widely used in many monitoring and control applications. In addition to direct pressure measurement, the pressure sensor indicators can also be used to indirectly measure other quantities, such as liquid/gas flow, velocity, water surface height, or altitude.

Application of Industrial Pressure Transducer


Pressure transmitter is the most commonly used smart pressure sensor in industrial practice. The standard pressure transmitter is widely used in various industrial automatic control environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemical, oil wells, power, ships, Machine tools, pipelines, and many other industries.


The industrial pressure transmitter can be divided into force (torque) balanced type, capacitive type, inductive type, strain type and frequency type according to different conversion principles. The following briefly introduces the principles, structure, Knowledge of use, maintenance, and calibration.


Working Principle of Industrial Pressure Transmitter


The electronic pressure transmitter is composed of a measuring diaphragm and electrodes on both sides of the insulating sheet to form a capacitor. When the pressure on both sides is inconsistent, the displacement of the measuring diaphragm is caused, and the displacement is proportional to the pressure difference, so the capacitance on both sides is unequal, through oscillation and demodulation.


The functional principle of different pressure transmitter could be slightly different from each other, among all the professional industrial instrumentation companies, You can learn more information about the measuring instrumentation at FEEJOY.
