Plants run better with Yokogawa differential pressure transmitters. At it's heart, Yokogawa's Differential Pressure Transmitter with DPharp digital sensor offers the performance and device intelligence needed to get greater insight into your process. 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 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 Digital DPharp sensor provides stable measurement in all operation conditions. Poor Performance = Lost Money *Maximum overpressure stability. 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. More Information = Found Money 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 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. More information = Found Money 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 Reduce unscheduled maintenance by 60%.Digital Performance
Accuracy Under All Operating Conditions
Stability Under All Operating 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.

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 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 = ReliabilityRugged Construction
