Details

What Are the Benefits of Draft Range Differential Pressure Transmitters?

Reduce maintenance cost by 33%.

Quicker = Less Downtime

Improved long-term stability extends calibration intervals. Spend your time where it is needed.

Multiple Communication Options

Save time. Save money

FieldMate PC based communication platform allows management of your entire instrument inventory.

FieldMate HHC allows you to take that information into the field.

LPS can update 9 parameters in the field without the use of an HHC.

Simple Troubleshooting

Save time. Save money

Local intuitive display with simple error messaging.

NE107 compliant alarms in FieldMate make troubleshooting easy.

 

Standard Protocols

No training required.

Yokogawa transmitters support all industry standard field device protocols. Interoperability and interchangeability can be ensured. Use the same tools and work procedures as before.

No Learning Curve = Smooth Change Over

 

Standard Industry Connections

Process connections designed to meet IEC61518 ensure you will not meet proprietary manifolds or accessories that limit your design choices.

How to Reduce Total Cost of Ownership?

Plants run better with Yokogawa pressure transmitters. At its heart, Yokogawa's Differential Pressure Transmitter with DPharp digital sensor offers the performance and device intelligence needed to get greater insight into your process.

 

Digital Performance

Poor Performance = Lost Money

Installed performance 2x better using all digital DPharp pressure sensor.

Yokogawa’s digital sensor provides superior performance and stability compared to analog sensors.

Dynamic Compensation

Compensates for process changes to improve accuracy.

 



 

 

 

Standard Diagnostics

Good Diagnostics = Less Surprises

Reduce unscheduled maintenance by 60%

Over 40 diagnostics to ensure everything is OK. Active Sensor Technology monitors the DPharp sensor while the Patented Back-check Technology is reverse checking all calculations in real-time.

How Are Draft Range Differential Pressure Transmitters Built?

Ruggedness = Reliability

Yokogawa's DPharp active sensor, patented back check diagnostics, and rugged construction allow users to run their plants safer and with less downtime. Yokogawa pressure transmitters help plants run longer. The transmitters are designed to outlive your plant and can reduce failures in the field by 200%.

 

Over-pressure Protection

Reduce failures and calibrations.

Yokogawa DPharp pressure transmitters have an integral over-pressure mechanism to protect your transmitters from process surges or improperly sequenced manifolds.

Proven Technology

Less Downtime = Making Product

 

Over 6 million DPharp transmitters are installed worldwide.

 

Reliability Guaranteed

Reliability verified independently by third party industry experts.

 

Inherently Safe

Inherently Safe = Reliability

Save up to 10% on CAPEX spending.

All Yokogawa pressure transmitters are certified to meet IEC61508 for single use in SIL 2 applications or dual use in SIL 3 applications as a standard. No special option needed! To Yokogawa, safety should never be an option.

 

Active Sensor Technology

Unlike other sensor technologies, the active DPharp sensor constantly produces a signal even if there is no change in the process. This signal is continually monitored by the CPU.

Patented Self-check System

All calculations are checked by reverse calculation in real-time ensuring the highest reliability.
