How to choose the right Yokogawa EJA530E pressure transmitter diaphragm capsule?

Principle of Yokogawa Transmitter

Because Yokogawa's transmitter has the advantages of ensuring high precision, maintaining negative pressure, temperature, and other environmental impacts, it has the advantage of performance. Electricity sales price that can be applied continuously for a long time. Small and medium-sized, lightweight, so that it is not restricted by the installation site, and is very popular in the market. Use microcomputer technology, with detailed self-diagnosis function and communication function.

Principle of EJA Differential Pressure Transmitter: Using electronic optics production and processing technology to make two H-shaped series resonant beams with the same appearance, specifications and materials on the management center and edge of a single crystal silicon integrated IC surface. The series resonant beams are in High frequency oscillation is made in the control loop of the resonant circuit. The different working pressures on the left and right surfaces of the monocrystalline silicon wafer will cause deformation, which will cause the management center series resonance beam to decrease in frequency due to compression force, and the edge series resonance will increase in frequency due to tensile force.

How to choose gauge pressure transducer

Yokogawa EJA530E pressure transmitter is a high-performance transmitter for measuring absolute pressure and pressure. It mainly measures the flow, level, density and pressure of liquid, gas or steam. Among all Yokogawa EJA-E series transmitters, there is another Yokogawa EJA430E that measures pressure. Today we are going to tell you how to choose the right Yokogawa EJA530E pressure transmitter diaphragm capsule.

Yokogawa EJA530E pressure transmitter has a total of four types of diaphragm capsule, each with the code ABCD code. Each capsule has a corresponding range. When the editor first started, I didn't quite understand how there are so many capsules. Why not make them into one? It is more convenient and laborious to mobilize all the ranges and ranges together! After a long time of study and progress, I learned that: the original Yokogawa transmitter has an accuracy ratio, and now the highest accuracy ratio of the pressure transmitter produced by Yokogawa has reached 0.055%. Yokogawa's accuracy ratio is between 0.02% and 0.06%. There is actually a percentage environment. If all the ranges are unified into one range and the accuracy percentage is used, then we will have a deviation in the measurement effect and the response will become larger.

The range of Yokogawa EJA530E pressure transmitter is 10-200kPa, 0.1-2MPa, 0.5-10MPa, 5-50MP. Pay attention to the unit on the back of the measuring range, be sure to distinguish the relationship between KPA and MPA. 1MPa=1000kPa, 1kPa=1000Pa. If your range is in PA as the unit, it is usually used to calculate the differential pressure value. If its range is less than 10KPA, we need to choose Yokogawa EJA430 pressure transmitter.

When choosing the diaphragm capsule of Yokogawa EJA530E pressure transmitter, we mainly confirm the measuring range from the on-site working conditions, and then we can select the appropriate diaphragm capsule according to the measuring range of the four diaphragm capsule.
