Predictive impulse line blocking and stream tracing diagnostics lets you see problems before they happen.
How to Reduce Total Cost of Ownership?
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.
Rugged Construction
Ruggedness = Reliability
Reduce failures in the field by 200%.
Yokogawa transmitters are designed to out live your planet.
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.
Quicker Maintenance
Routine maintenance is easier with Yokogawa pressure transmitters. Efficient and effective maintenance through extended calibration intervals and simple trouble shooting.
Extended Calibration Intervals
Reduce maintenance cost by 33%.
Improved long-term stability extends calibration intervals. Spend your time where it is needed.
Quicker = Less Downtime
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.
Less Inventory
Universal Mounting
Reduce stock by 50%
Consolidate inventory of different flange configurations. Yokogawa transmitters are available with flanges using flexible vent and drain locations to met any installation need.
High Inventory = Stagnant Money
Safety as Standard
Reduce stock
No need to stock separate inventory for safety and non-safety applications. With safety as a standard, Yokogawa transmitters can be used for either application.
For Yokogawa, safety is never an option.
Standard Protocols
No Learning Curve = Smooth Change Over
Yokogawa transmitters support all industry standard field device protocols. Interoperability and interchangeability can be ensured. Use the same tools and work procedures as before.
Standard Industry Connections
Process connections designed to meet IEC61518 ensure you will not meet proprietary manifolds or accessories that limit your design choices.

EJX310A Absolute Pressure Transmitter Calibration
From Differential Pressure and Pressure Transmitters Manual. Use the procedure below to check instrument operation and accuracy during periodic maintenance or troubleshooting.
1) Connect the instruments as shown in figure 8.1 and warm up the instruments for at least ten minutes
2) Apply reference pressures of 0%, 50%, and 100% of the measurement range to the transmitter. Calculate the errors (differences between digital voltmeter readings and reference pressures) as the pressure is increased from 0% to 100% and is decreased from 100% to 0%, and confirm that the errors are within the required accuracy
