Keywords of this article: EJA. http://www.shqyyb.com/ 1. Simplification of system components: The EJA pressure transmitter can produce an output signal that is proportional to the square root of the input differential pressure signal, through simple settings. Thus, there is no need for a square-root calculation module used in differential pressure flow meters. This simplifies the structure of the measurement and control systems. The benefits are self-evident. At the same time, small-signal rejection after square-rooting also has its unique advantages. There are two methods for small-signal clipping. The first is similar to a regular square root circuit: it performs complete clipping when the output signal is below the clipping point, and this is referred to as the \"zero-clipping method.\" The second method involves a linear relationship between the output signal and the input differential signal when the output signal is below the clipping point. The resection points for the two resection methods can be adjusted continuously within the range of 0% to 20%. The linear cutting method is beneficial for on-site operations when measuring the lower limit flow rate. 2. Typically, conventional differential pressure transmitters do not have as large a rangeability as EJA differential pressure transmitters. To meet production requirements, two differential pressure transmitters are actually installed for measuring this flow rate. The EJA pressure transmitters and differential pressure transmitters feature a large range ratio. It also possesses self-setting and self-checking capabilities. It is used for measuring main line flow rates; the same purpose can be achieved by using an intelligent terminal in the control room to adjust the differential pressure values for both low and high ranges. It eliminates the need for disassembly, assembly, and calibration of conventional differential pressure transmitters. This reduces the maintenance workload for instrument technicians and decreases the quantity of spare transmitters required. 3. It is easy to make simple settings using various on-site display instruments for parameters, enabling the built-in LCD module of the EJA differential pressure transmitter to display various types of data. Such as pressure transmitters, which allow the LCD to display the input pressure along with the corresponding unit; EJA differential pressure transmitters and pressure transmitters that enable the LCD to show flow rate values with custom units, etc. In some cases, on-site indicating instruments such as pressure gauges and rotameters can be omitted without affecting on-site monitoring and operation. The LCD display module of the EJA differential pressure transmitter features a mandatory self-diagnosis display function. Should the measured parameter exceed the range or if a fault occurs in the transmitter itself, the LCD displays an error code instead of the originally set parameters, facilitating timely troubleshooting. If using a smart terminal, more process information can be read from the Yokogawa EJA differential pressure transmitters. Shanghai Quanyun Instrument Co., Ltd.
