Description
The EJX118A is a_differential pressure transmitter with remote diaphragm seals and_is part of_the EJX-A series._They_can be used to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. EJX118A outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via BRAIN or HART communications.
The EJX118A is the Differential Pressure Transmitter with Remote Diaphragm Seals in the series.
EJX118A features include:
- ± 0.15% Accuracy
- 200 ms Response Time
- Exida and TUV SIL2 / SIL3 Certified
- Local Parameter Setting (LPS)
- 10-segment Signal Charaterizer
- Active Capillary Fill Fluid Density Compensation
Digital Performance
Yokogawa’s DPharp digital sensor offers twice the performance and stability of the competitor’s analog sensors. The DPharp uses the latest in IC Chip-style design and manufacturing technology. Analog sensors are based on older design technology. Although analog sensors are good, the modern DPharp sensor out performs them. A Yokogawa transmitter with DPharp digital sensor will give you the consistent, reliable, accurate measurement you need.
Superior Design
All remote seal system on the market use fill fluid to ‘transmit’ the process pressure from the remote diaphragm seal to the pressure sensor in the transmitter. The physical properties of the fill fluid change has process temperature and ambient temperature change causing the transmitter to measure inaccurately. This effect get worse the longer the capillaries are. The key is to filter out this ‘noise’ to get an accurate, consistent, reliable measurement. Yokogawa has a superior design, manufacturing process, and features to reduce this ‘noise’.
Signal Characterization
Signal characterization is a versatile function available on all Yokogawa pressure transmitters. The function is used to compensate the analog 4 to 20 mA output signal for non-linear applications. Such applications include tank strapping or flow measurements; but, it can be used in any application where the relationship between the pressure input and the desired output signal are known. This feature can use up to 10-points.
Rugged Construction
Ruggedly constructed differential pressure transmitter can help your plant reduce failures. Yokogawa’s DP transmitters have construction features that are designed to allow it to outlive your plant. Four-bolt pressure retaining design, Active DPharp sensor, and dual seal certified to ANSI/ISA 12.27.01 – all design features to extend the life of the transmitter.
Extended Calibration Intervals
Yokogawa EJX-A series pressure transmitters have a long-term stability under all operational conditions. As you gain experience with these transmitters, you will be able to extend the time between calibration checks.
Multiple Communication Options
Yokogawa offers several platforms to communicate to your transmitter.
FieldMate is a PC based communication platform that can communicate with your transmitter and manage your entire instrument inventory.
FieldMate HHC is a traditional hand-held platform that allows you to take that information into the field.
Forgot your HHC? No problem. The LPS feature on the transmitter allows you to update 9 parameters without the use of an HHC.
