EJA110E YOKOGAWA PDF

Predictive impulse line blocking and stream tracing diagnostics lets you see problems before they happen. Rugged Construction Ruggedly constructed differential pressure transmitter can help your plant reduce failures. Yokogawa pressure transmitters have construction features that are designed to allow it to outlive your plant. But, Yokogawa goes a step further and adds a mechanical system within the capsule to protect the transmitter from over pressure events. These events could be caused by anything from unexpected process surges to improperly sequenced manifolds. They are certified for single transmitter use in SIL 2 safety applications and dual transmitter use in SIL 3 safety applications with no special option required.

This ensures on-spec product, reduced waste, and improved yield, helping you increase profitability. Analog sensors can only measure DP and sensor temperature and therefore can only compensate for temperature effect.

Given these three pieces of process data, our differential pressure transmitters compensate the DP measurement for temperature effect and static pressure effect in real time. This compensation is referred to as Dynamic Compensation and improves DP measurement accuracy. Learn more about Dynamic Compensation. Overpressure events such as incorrect sequencing of a manifold during start-up or shutdown and process upsets can damage analog sensors, requiring the transmitter to be recalibrated - or even replaced - in order to return it to normal operations.

A mechanical system within the transmitter provides additional overpressure protection by equalizing the excessive pressure before it reaches the sensor. Once it returns to normal operating pressure, the transmitter returns to operation within the defined accuracy and stability specifications with no need for recalibration. The Yokogawa DPharp sensor has a more significant operational envelope compared to an analog sensor, allowing you to run your control loop at your desired set-point regardless of process conditions.

The EJAE reduces total cost of ownership by having safety as standard, extending calibration intervals, and giving users the option to measure both differential and static pressure with one transmitter. As standard, all Yokogawa transmitters are certified for single transmitter use in SIL 2 safety applications and dual transmitter use in SIL 3 safety applications.

The same transmitter can be used for both process control and safety applications. Managing two separate transmitter models is no longer necessary, reducing spares inventory and simplifying daily operations.

Changing operating conditions can cause transmitters to drift to the point where they are no longer able to make accurate measurements for the process loop they are installed in, resulting in poor quality or an impact to product yields. As you gain experience with these transmitters, the interval between calibration checks is extended.

Spend your time where it is needed. With our DP transmitter, there are fewer devices to manage, maintain and calibrate, lowering overall lifecycle costs. Interoperability and interchangeability can be ensured. Use all the same tools and work procedures as before. International Certifications With the rapid globalization of markets, numerous international standards and approvals are becoming necessary.
