Descripción

En esencia, el transmisor de presión diferencial de Yokogawa con sensor digital DPharp ofrece el rendimiento y la inteligencia de dispositivo necesarios para obtener una mayor comprensión de su proceso.

Digital Performance

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

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

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

More Information

More Information

Save up to 20% on CAPEX spending using the DPharp’s multi-sensing capability. With our competitor’s transmitters using analog sensors, any application that requires measurement of both differential pressure (DP) and static pressure (SP) requires two separate transmitters – one to measure the DP and one to measure the SP. Yokogawa’s differential pressure transmitter with multi-sensing DPharp sensor, can measure both process variables (DP and SP) with a single transmitter. Two transmitters will always cost more than one transmitter.

Signal Characterization

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.

Greater Flexibility = Found Money

 

Local Indicator

Local Indicator

All of the process variable’s measured by Yokogawa’s transmitter can be displayed on the easy to read local indicator. The indicator can display any of the variables measured (DP, SP, Capsule temperature); alarm codes with short text; and a sweeping bar graph to give a graphical representation of the process. Fully programmable, the indicator is customizable for your needs. Unlike competitor’s transmitters, the indicator is not driven off the 4 to 20 mA analog signal, but, exist on a separate circuit. This allow the display to operate independently from the output signal, so it can indicate information that maybe more useful at the transmitter location.

Standard Diagnostics

Yokogawa’s transmitter has 40 self-diagnostic checks to ensure that everything is running smoothly within the transmitter. But, all transmitters on the market have a level self-diagnostic checks. However, Yokogawa has two that are not offered by competitors. First, the transmitter features a patented Back-check Technology that reverse checks all calculations in real-time. Second, the DPharp sensor is an active sensor. This means that the sensor is constantly supplying a signal even when the process has not changed. If the signal is lost from the sensor, the transmitter knows there is an issue. Competitor’s analog sensors are passive. They do not supply a continual signal, so, is the sensor still working when there is no signal?

Good Diagnostics = Less Surprises

Rugged Construction

Rugged Construction-EJA110E

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. Four-bolt pressure retaining design, Active DPharp sensor, Teflon coated 316L stainless steel flange gasket, and dual seal certified to ANSI/ISA 12.27.01 – all design features to extend the life of the transmitter.

Note: For conformance to NACE MR0175/MR0103, please refer to General Specifications of each model.

Ruggedness = Reliability

 

Over-pressure Protection

Over-pressure Protection

Yokogawa’s DPharp pressure sensor has over-pressure protection from the simple robust design of the sensor itself. 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.

Ruggedness = Reliability

 

Independent Verification

Independent Verification

The Yokogawa pressure transmitter series’ performance and reliability has been verified by independent third parties from around the world.

 

Functional Safety

Functional Safety

All Yokogawa pressure transmitters are designed and certified to IEC61508:2010 Parts 1 through 7 and IEC61511:2004 Parts 1 through 3. 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. With Yokogawa’s transmitters, no longer will you have to maintain two seperate inventories – one for production applications and one for safety applications.

Functional Safety = Reliability

 

Active Sensor Technology

Active Sensor Technology

The DPharp sensor is an active sensor. This means that the sensor is constantly supplying a signal even when the process has not changed. If the signal is lost from the sensor, the transmitter knows there is an issue. Competitor’s analog sensors are passive. They do not supply a continual signal, so is the sensor still working when there is no signal? An active sensor is inherently safe.

Inherently Safe = Reliability

 

Patented Self-check System

Patented Self-check System

Yokogawa’s pressure transmitters as a patented real-time reverse check of the signal to ensure all calculations are preformed correctly. This system ensures that the transmitter is converting the signal from the sensor into the analog signal and digital protocol correctly.

Inherently Safe = Reliability

Yokogawa’s DPharp pressure transmitters offer long-term stability and diagnostics to make your maintenance routine easy.

 

Extended Calibration Intervals

Extended Calibration Intervals

Yokogawa’s 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.

Quicker Maintenance = Less Downtime

 

Multiple Communication Options

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.

Quicker Maintenance = Less Downtime

 

Simple Troubleshooting

Simple Troubleshooting

When your transmitter is ‘alarming’, you do not have the time to look for the manuals and go through them trying to figure out what is wrong; you need to get the transmitter up and operating again as quick as possible. Yokogawa’s pressure transmitters have a simple description of the error code available on the local display. This simple description may help you correct the problem and get back to making product quickly. If you need more help, the manual does have a full description of all codes and suggest corrective actions. 

Quicker Maintenance = Less Downtime

 

Universal Mounting

Universal Mounting

Pressure transmitters on the market have several different flange configuration depending on the medium being measured (Gas or liquid). This requires plants that process both medium to maintain a stock of both types of configurations. Yokogawa’s pressure transmitters offer a universal mount that can be configured to handle either Gas or Liquid; reducing your inventory of replacement transmitters.

High Inventory = Stagnant Money

 

Standard Industry Process Connections

Standard Industry Process Connections

Yokogawa’s pressure transmitters use the industry standard IEC61518 process connection deminsions. This ensures you will not need proprietary manifolds or accessories that limit your design choices. The IEC61518 standard gives you the piece of mind that if you ever want to make a change in transmitter manufacturer, you can. Some competitors have proprietary process connections that do nothing more than lock you into buying their product as replacements.

No learning Curve = Smooth Change Over
