D-Series

Product catalog summary

Technical Datasheet Overview: This document provides detailed specifications and guidelines for the D-Series Flanged Seals with Flush Diaphragm, specifically the S-P models. It includes dimensions, applications, measuring ranges, material specifications, and ordering information.

Specifications: The datasheet outlines the dimensions for various diaphragm seal versions (DN50, DN80, DN100) with details on diaphragm diameter, contact face diameter, bolt circle diameter, external diameter, thickness, and number of holes. Capillary lengths range from 1 to 3 meters, with special versions up to 6 meters.

Applications: The diaphragm seal is used to transmit pressure signals to measuring devices while isolating them from damaging impacts such as extreme temperatures, high viscosity, impurities, and vibrations.

Measuring Ranges: The document specifies recommended minimum measuring ranges for different diaphragm seal types and pressure measuring devices. It also addresses absolute zero error due to ambient temperature fluctuations.

Temperature and Pressure Limits: The temperature range for measured mediums varies based on the type of diaphragm seal and manometric liquid used. Maximum pressure ratings are 40 bar for PN40 and 150 psi for ANSI 150. Materials used include 316L stainless steel.

Recommendations: To minimize thermal zero error, it is advised to use shorter capillaries, larger diameter seals, and place capillaries in areas with minimal temperature fluctuations.

Ordering Information: The document provides a format for ordering, including details on the pressure transmitter, diaphragm seal version, capillary length, and type of manometric liquid.

Contact Information: Delta Controls Limited provides contact details for further inquiries and reserves the right to amend the document without notice.

Application The diaphragm seal is a pressure transmitting, diaphragm-type device. The pressure signal is sent to the cooperating pressure measuring device (pressure transmitter, pressure gauge) through manometric liquid ﬁlling the space between the separating diaphragm of the seal and the pressure measuring device. The diaphragm seal task is to isolate the pressure measuring device from damaging impacts caused by either medium or installation: s Low or high temperature, increased viscosity, and impurities s Vibrations of the installation (remote diaphragm seal) Measuring Ranges Recommended minimum...
