Product catalog summary

Overview: The document provides comprehensive specifications and applications for Yokogawa Electric Corporation's Diaphragm Seal Systems. These systems are designed to measure parameters such as flow, level, density, and pressure of liquids, gases, or steam, while preventing the process medium from entering the pressure-sensing assembly of transmitters.

Applications: These systems are suitable for handling high/low temperature fluids, corrosive or viscous fluids, fluids prone to clogging, toxic fluids, and those with suspended solids.

Communication Types: The document mentions communication types like FOUNDATION Fieldbus and PROFIBUS PA, with specific GS numbers for each.

Diaphragm Seal System Types: Various types are outlined, including Inner Diaphragm Type, Direct Mounted, Digital Remote Sensor, Hygienic, and Absolute Pressure Diaphragm Seal Systems.

Features: Emphasizes high performance, accuracy, and reliability, with capabilities for high temperature and vacuum use, fast response times, and segment signal characterization.

Compensating Capillary Design: This design balances the volume and temperature of fill fluids, reducing ambient temperature influence.

Product Specifications: Detailed specifications include process connection sizes and applicable transmitter models.

Span and Range Limits: Tables detail measurement span and range limits for different systems, categorized by pressure type and connection style.

Remote Mount Flanged Diaphragm Seal Specifications: Includes temperature range, seal system location, seal fill fluid options, transmitter connection type, capillary length and diameter, process connection size, sealing face, diaphragm material, flange standards, and pressure ratings.

Material Considerations: Users must consider wetted parts material characteristics and process fluid influence to prevent leakage and contamination.

Process and Ambient Temperature: Specifications for silicone oil, fluorinated oil, and ethylene glycol are provided, detailing their temperature ranges.

Installation Note: Differential pressure transmitters should be installed at least 600 mm below the high-pressure process connection, with variations based on conditions.

Specifications: Details on isolating diaphragms, process and ambient temperatures, working pressures, and specific gravity for various fill fluids are provided.

Procedures: Installation guidelines emphasize the importance of proper installation based on ambient temperature, operating pressure, fill fluid, or diaphragm material.

Norms and Standards: References standards like NACE MR0175 (2003) for material recommendations.

Recommendations: Users should consider wetted parts materials and process fluids, especially for corrosive fluids. Contact with Yokogawa is recommended for detailed material information.

Key Data from Tables: Tables provide information on diaphragm materials, sealing face materials, and capillary specifications.

Critical Information: Selecting the correct fill fluid and diaphragm material is crucial for safety and contamination prevention.

Material Specifications and Recommendations: Emphasizes selecting appropriate materials for wetted parts to prevent contamination and damage, with recommendations for materials like Hastelloy C-276 and 316 SST.

Temperature and Pressure Specifications: Detailed specifications for process and ambient temperatures, working pressures, and specific gravity for different fluids are provided.

Diaphragm Seal Systems: Describes various models and configurations, including direct mount hygienic diaphragm seals and flushing connection rings.

Optional Specifications: Includes features like operating temperature correction and pressure/leak test certificates.

Key Tables and Figures: Tables provide critical data on material compatibility, temperature and pressure limits, and optional specifications.

Flange Specifications: Outlines specifications for different flange sizes and standards, including dimensions and bolt hole details.

Diaphragm Seal Types: Describes various types, including remote mount hygienic diaphragm seals and direct mount flanged diaphragm seals.

Extended Length Options: Provides options for extended lengths with specific codes.

Applicable Products: Lists applicable products, including differential pressure transmitters and their compatible diaphragm seal systems.

Key Considerations: Emphasizes selecting the correct flange and diaphragm seal configurations based on application requirements.

Ordering Information: Outlines the process for ordering, including model, suffix codes, option codes, calibration range, units, output mode, display scale, and tag number.

Software Tag Configuration: Specifies characters for 'Tag' and 'Long tag' in the amplifier memory.

Factory Configurations: Option code CA allows further configuration at the factory, including descriptor, message, and software damping settings.

Material Cross Reference: Cross-references ASTM grades with JIS grades.

<<Contents>> <<Index>> DPharpEJpt DP harp EJfir [Diaphragm Seal System] Diaphragm Seal System can be used to measure liquid, gas, or steam flow as well as liquid level, density, and pressure. Diaphragm seals are used to prevent process medium form entering directly into the pressure-sensing assembly of the differential or Gauge pressure transmitter. Application which is suitable for diaphragm seal system For measuring the flow of ; • high/lowtemperature fluids • highly corrosive/high viscosity fluids • the fluids which may cause clogging of impulse piping in the low temperature • toxic fluids • the fluids containing suspended solids which are deposited in the impulse piping and may cause clogging. Venting/draining can be operated by installing the flushing connection ring, Adapter connection type Flange connection type Diaphragm Seal System (Inner Diaphragm type) Refer to GS as of the table below for Fieldbus communication type and PROFIBUS PA communication type for the items marked with “0.” Direct Mounted Diaphragm Seal System The codes of diaphragm seal system represent a seal system type. CE and other standard certification are acquired for each transmitter section.
