Description 


EJA118W Double Fremate liquid level meter can be used to measure the flow of liquid, gas or steam, as well as liquid levels, density and pressure.

The sealing diaphragm is used to prevent the process medium from directly entering the pressure sensor component of the differential pressure transmitter. They are connected to the transmitter by the capillary of the fluid.


EJA118W Double Fremid Line Putting Excellent Performance and Stability

The EJA series uses single crystal silicon resonant sensor technology. Single crystal silicon does not have a lag in changes in pressure or temperature, and is an ideal material. Single -crystal silicon resonance sensors reduce the impact of over pressure, temperature changes, and static pressure to#low, thereby providing unparalleled long -term stability.



Small lightweight design of the liquid level meter

Due to the use of ASIC amplifier design to make the packaging smaller, as well as the film box structure and the miniaturization of flange, the weight of this model is reduced to half of the original model. ASIC design not 

only reduces the number of parts, but also improves the reliability of the amplifier.



Liquid position on site bus communication capabilities

The on -site bus is a two -way digital communication system. It is an innovative technology of configuring the instrument control system. At the same time, it is also a well -known update product for replace the standard 4 ~ 20mA simulation communication widely used in on -site instruments.

The EJA series provides two on -site bus models, Foundation ™ live bus low -voltage mode and Profibus PA device to achieve the coordinated work of Henghe Electric and other suppliers. In terms of software, the EJA series uses two AI function blocks to calculate differential pressure and static pressure, thereby achieving flexible instrument configuration.
