Pressure sensors, transducers, and switches are commonly used in industrial and commercial settings to measure changes in pressure and convert them into readable signals or follow-up alarms. As a chief member of the pressure sensing element, 4 inch-D-grade-mini pressure sensors are widely used due to its smaller size, higher sensitivity, longer service life, and better accuracy. This article focuses on the principle of 4 inch-D-grade-mini pressure sensors and its application fields.

The miniature pressure transducers are widely applied for measuring atmospheric pressure, liquid pressure, gas pressure, and vacuum pressure in industries such as refinery, metallurgy, chemical, power, and construction sites. For instance, they can be used to monitor the pressure in a water tank and provide an alarm when the pressure reaches a certain level. In addition, these indispensable elements are also broadly used to monitor or control pressure systems in the offshore platform, nuclear power station, electric power generating station, and other areas.

In short, 4 inch-D-grade-mini pressure sensors are adopted to detect and track pressure variations in many industrial settings. These pressure sensors are equipped with a wide range of features and technologies, making them highly reliable and efficient.

The working principle of 4 inch-D-grade-mini pressure sensors can be divided into two aspects, i.e., measuring the diaphragm displacement and sensing the pressure. The central core of the miniature pressure transducer consists of a stainless steel diaphragm, a capillary tube, a spring, and other workable components. The elastic material of the diaphragm deflects or moves under the external pressure. The shape change of the spring is then linked to the displacement of the diaphragm. In this way, the external pressure is accurately detecting and converted into an electrical signal that can be easily read.

When being used, the mechanical force signal of the 4 inch-D-grade-mini pressure transducer is transmitted to the measuring bridge through a transmission belt or a gear. Then, a voltage signal is developed and further transferred to the amplifier or indicating instrument. Lastly, the number is converted as digital signal and transmitted to the general control system for processing, storing, and reading.

In conclusion, 4 inch-D-grade-mini pressure sensors are used widely in industries such as metallurgy, chemical, and power due to its higher sensitivity, longer service life, and better accuracy. Furthermore, its working principle is accredited to the displacement of the diaphragm, the shape change of the spring, and the pressure sensing technology.
