YOKOGAWA EJA210E Flange Mounted Differential Pressure Transmitter
YOKOGAWA EJA210E Flange Mounted Differential Pressure Transmitter
Product Description
YOKOGAWA EJA210E Flange Mounted Differential Pressure Transmitters
The high performance flange mounted differential pressure transmitter EJA210E can be used to measure levels of densities of solidifying or precipitating liquids. EJA210E outputs a 4 to 20 mA DC signal corresponding to the measured differential 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.
All EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS and Low Power types, are certified as complying with SIL 2 for safety requirement.
Features
The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family of pressure transmitters. Released in 2012, it combines the ruggedness and success of the work-horse EJA-A series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.
The EJA210E is the Flange-mount Liquid Level Transmitter in the series.
EJA210E features include:
± 0.075% Accuracy
± 0.1% per 1 year Stability
120 msec Response Time
Exida and TUV SIL2 / SIL3 Certified
Signal Characterizer for the 4 to 20 mA output

Benefits
Cost - saving: The compound sensing function of the DPharp digital sensor allows a single transmitter to measure two process variables, differential pressure and static pressure, without the need to set up separate transmitters, saving up to 20% of the capital expenditure (CAPEX). In addition, due to its long - term stability, the calibration interval can be extended, reducing maintenance costs.
High - reliability: With 40 self - diagnostic functions, including the unique Back - Check technology and active sensor characteristics, it can detect sensor failures in a timely manner, improving the reliability and safety of equipment. And it has passed the certification of international independent third - party institutions TÜV Rheinland and EXIDA, and its performance and reliability are guaranteed.
Easy to Integrate: It supports a variety of communication protocols, such as HART 5/7, HART (1 - 5V DC) low - power type, FF field - bus, PROFIBUS PA, and BRAIN. This makes it easy to communicate with a variety of control systems and instruments, facilitating system integration and data transmission
