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.
