  • Yokogawa has more than 45 years' experience in the development, design, and manufacture of pressure sensors and pressure transmitters. The DPharp series of digital pressure transmitters use a differential pressure high accuracy resonance (DPharp) sensor that represents one of the most revolutionary advances in transmitter technology.

  • The flexibility of wireless solutions enables less investment in infrastructure while providing greater insights into plant operations.

  • Yokogawa offers a variety of communication protocols; including, FOUNDATION Fieldbus, HART, BRAIN, ISA100, Profibus, and Modbus to help support smart devices in this evolving digital communication technology.

  • Yokogawa’s DTSX solution ensures a safe work environment and total insight into the process being measured and provides a complete, simple and cost-effective solution to complex temperature measurements.

  • Remote Indicators can be a valuable addition to process measurements by providing local visual awareness of your process variables. Yokogawa offers several different Indicators for you needs.

  • Yokogawa has more than 40 years' experience in the development, design and manufacture of valve positioners and converters. They provide superior controllability and maintenance ability, which contributes to reduced plant operation costs.

  • The new Yokogawa CA700 Portable Pressure Calibrator is equipped with a silicon resonant sensor that uses Yokogawa proprietary DPHARP technology. The CA700 can measure pressures with an accuracy that is within ±0.01% of rdg*, making it one of the most accurate portable pressure calibrators on the market.

  • Yokogawa offers a wide range of flow computers/totalizers, batch controllers and thermal energy calculators. Accepting signals from our vortex and magnetic flowmeters, the instruments are also suitable for use with other flow measurement technologies, including turbine, differential pressure, and target type flowmeters.

  • HART Converters consist of the Smart HART loop interfaces and monitors; as well as, HART concentrator systems and HART-to-MODBUS RTU.

Edition 2
Overview:

Yokogawa diaphragm seal systems are available with an optional Flushing Ring.  A flushing ring is metal donut-shaped ring installed between the seal and the customer process connection. It is a wetted part. The ring has a port(s) that can be used to flush the surface of the diaphragm during cleaning. The ports are threaded and available in either ¼-inch or ½-inch sizes. The ports are available with extensions to make them easier to reach. The ring may also have ring holders to ensure the entire assembly aligns correctly to prevent leaks.

The ring can be referred to as a Calibration Ring. The flushing ports on the side of the ring allow the user to apply a calibration pressure and consequently calibrate the unit against that pressure. Calibration is accomplished by sandwiching the calibration ring between the remote seal and a blank process flange.

The ring can also serve as a reducer, a spacer, or a heat sink.

The ring is available as part of the diaphragm seal model code or as a separate line item.

Overview:

Larger diameter diaphragms have lower spring rates compared to smaller diameter diaphragms. Consequently, they are more flexible. As fill fluids contract and expand with temperature gradients from the process and ambient conditions, the larger diameter diaphragm can deflect without conveying a pressure change to the sensor. The smaller diameter, rigid diaphragm will not deflect as much and will cause drift in the pressure sensor reading proportional to the temperature change. This drift is usually small in magnitude.
