Yokogawa Eja510e in-Line Mount Absolute Pressure Transmitter

Product Description

YOKOGAWA EJA510E In-Line Mount Absolute Pressure Transmitter

The high performance absolute and gauge pressure transmitter EJA510E and EJA530E feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure. EJA510E and EJA530E output a 4 to 20 mA DC signal corresponding to the measured pressure. It also
features quick response, remote setup and monitoring via BRAIN or HART communications and selfdiagnostics. 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 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. Released in 2012, it combines the ruggedness and success of the work-horse EJA-E series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.

The EJA510E is our in-line mount absolute pressure transmitter in the series.

EJA510E features include:

± 0.055% Accuracy (0.04% Accuracy optional)
± 0.2% Stability per 10 years
90 ms Response Time
Exida and TUV SIL 2/3 Certified
8,700 psia Maximum Over Pressure
Local Parameter Setting (LPS)

Applications

Industrial Process Monitoring: In various industrial production processes, such as chemical, petrochemical, and power industries, it is used to monitor the absolute pressure of process fluids. For example, in chemical reaction vessels, it can measure the absolute pressure inside the vessel to ensure that the reaction proceeds under the correct pressure conditions, helping operators to control the process and prevent safety accidents caused by over - pressure or under - pressure

Flow Measurement: It can be used in conjunction with other devices for flow measurement. According to the principle of fluid mechanics, there is a certain relationship between pressure and flow. By measuring the absolute pressure, and combining with parameters such as pipeline diameter and fluid properties, the flow rate of the fluid in the pipeline can be calculated, so as to realize the monitoring and control of the flow.
