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.

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 consistentreliableaccurate measurement you need.

Poor Performance = Lost Money


Superior Design

All remote seal system on the market use fill fluid to ‘transmit’ the process pressure from the remote diaphragm seal to the pressure sensor in the transmitter. The physical properties of the fill fluid change has process temperature and ambient temperature change causing the transmitter to measure inaccurately. This effect get worse the longer the capillaries are. The key is to filter out this ‘noise’ to get an accurateconsistentreliable measurement. Yokogawa has a superior design, manufacturing process, and features to reduce this ‘noise’. See FieldGuide FGP-340 YokogawaDiaphragm Seal Transmitter (DFS) for details.

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. See FieldGuide FGP-150 Signal Characterization for details. It is available under the Download tab above.
