EJA130E

Differential Pressure Transmitter
The high performance diff erential pressure transmitter EJA130E features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam fl ow as well as liquid level, density and pressure.
EJA130E outputs a 4 to 20 mA DC signal corresponding to the measured diff erential pressure.
Its 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.
Other key features include quick response, remote set-up using communications and self-diagnostics.
FOUNDATION Fieldbus, PROFIBUS PA and 1 to 5 V DC with HART (Low Power) protocol types are also available.
EJA-E series models in their standard confi guration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certifi ed as complying with SIL 2 for safety requirement.

The EJA130E is a differential pressure transmitter designed to work in a high static pressure enviroment.

EJA130E features include:

Available with HART 5/7, 1 to 5 VDC HART 7 (Low Power), FOUNDATION FieldBus, PROFIBUS PA, or BRAIN communication.

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.

Poor Performance = Lost Money

Accuracy Under All Operating Conditions

Yokogawa’s DPharp sensor has the ability to measure the differential pressure (DP), static pressure (SP), and sensor temperature from a single sensor. Giving these three pieces of process data, Yokogawa’s transmitter can compensate the DP measurement for Temperature Effect and Static Pressure Effect in real time. This is referred to as Dynamic Compensation and improves the DP measurement accuracy.

Competitor’s analog sensors can only measure DP and Sensor temperature. So, theirs can compensate for temperature Effect; but, since the SP measurement is missing, it cannot compensate for Static Pressure Effects.

Poor Performance = Lost Money

Stability Under All Operating Conditions

Digital DPharp sensor provides stable measurement in all operation conditions.
To some degree, all pressure sensors on the market provide stable measurement with variations in temperature and static pressure. But what happens when the sensor is over-pressured (pressure > sensor Upper Range Limit (URL)) – like occurs when a manifold is incorrectly sequenced during start-up or shutdown? Or a process upset? Analog sensors are actually damaged during these events requiring the transmitter to be recalibrated to return to accurate operation or even replaced. Yokogawa’s transmitters can withstand large overpressure events. (*See the table below.) Once it returns to normal operating pressure (pressure < URL of the sensor), the transmitter will return to operation within the defined accuracy and stability specifications - no need to recalibrate. Basically, the Yokogawa DPharp sensor has a larger operational envelope compared to an analog sensor. Poor Performance = Lost Money

Kinerja Digital

Sensor digital DPharp Yokogawa menawarkan kinerja dan stabilitas dua kali lipat dari sensor analog pesaingnya. DPharp menggunakan desain dan teknologi manufaktur Chip IC terbaru. Sensor analog didasarkan pada teknologi desain lama. Meskipun sensor analog bagus, sensor DPharp modern mengungguli mereka. Pemancar Yokogawa dengan sensor digital DPharp akan memberi Anda pengukuran yang konsisten, dapat diandalkan, akurat yang Anda butuhkan.

Kinerja Buruk = Kehilangan Uang

Akurasi Dalam Semua Kondisi Pengoperasian

Sensor DPharp Yokogawa memiliki kemampuan untuk mengukur tekanan diferensial (DP), tekanan statis (SP), dan suhu sensor dari satu sensor. Dengan memberikan ketiga bagian data proses ini, pemancar Yokogawa dapat mengompensasi pengukuran DP untuk Efek Suhu dan Efek Tekanan Statis secara real time. Ini disebut sebagai Kompensasi Dinamis dan meningkatkan akurasi pengukuran DP.

Sensor analog pesaing hanya dapat mengukur DP dan suhu Sensor. Jadi, sensor mereka dapat mengompensasi Efek suhu; tetapi, karena pengukuran SP tidak ada, maka sensor tersebut tidak dapat mengompensasi Efek Tekanan Statis.

Kinerja Buruk = Kehilangan Uang

Stabilitas di Bawah Semua Kondisi Operasi

Sensor DPharp digital memberikan pengukuran yang stabil di semua kondisi operasi. Hingga taraf tertentu, semua sensor tekanan di pasaran menyediakan pengukuran yang stabil dengan variasi suhu dan tekanan statis. Namun, apa yang terjadi jika sensor mengalami tekanan berlebih (tekanan > Batas Atas Rentang Sensor (URL)) – seperti yang terjadi saat manifold diurutkan secara tidak benar selama memulai atau mematikan? Atau proses terganggu? Sensor analog sebenarnya rusak selama kejadian ini sehingga memerlukan kalibrasi ulang pemancar untuk kembali beroperasi secara akurat atau bahkan diganti. Pemancar Yokogawa dapat menahan kejadian tekanan berlebih yang besar. (*Lihat tabel di bawah.) Setelah kembali ke tekanan operasi normal (tekanan Kinerja Buruk = Kehilangan Uang
