Flanged seals with flush diaphragm S-P

Product catalog summary

Flanged Seals with Flush Diaphragm S-P

Diaphragm Seal Dimensions: The document provides detailed dimensions for diaphragm seals, including diaphragm diameter, contact face diameter, bolt circle diameter, external diameter, thickness, hole diameter, and the number of holes for different standards such as DN50 PN40/2’’ANSI 150, DN80 PN40/3’’ ANSI 150, and DN100 PN40/4’’ ANSI 150.

Application: Diaphragm seals are used to transmit pressure signals to pressure measuring devices while isolating them from damaging impacts such as temperature extremes, increased viscosity, impurities, and vibrations. They can be connected remotely or directly to smart and analog pressure transmitters and gauges.

Ordering Procedure: The document outlines the procedure for ordering direct and remote diaphragm seals, specifying the pressure measuring device, diaphragm seal version, capillary length, and type of manometric liquid. It highlights the importance of standard outlet capillary configurations and provides recommended minimum measuring ranges for different setups.

Recommendations: To minimize thermal zero error due to manometer liquid expansion, it is recommended to use short capillaries, larger diameter seals, and place capillaries in areas with minimal temperature fluctuations. The document provides zero error values for different diaphragm seal types and configurations.

Temperature and Pressure Specifications: The document specifies temperature ranges for different manometric liquids and maximum pressures for PN40 and ANSI 150 standards. It also notes the material of the diaphragm and flange as 316L stainless steel.

Special Versions and Mounting: Special versions include other ANSI or DIN standards, edible oil filling, and direct diaphragm seals for high temperatures. Capillary mounting options include axial (standard) and radial (on request).

Flanged seals with flush diaphragm S-P-1

Remote connection with: smart and analog pressure and differential pressure transmitters gauges: 063, 0100 Diaphragm seal dimensions Version 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:

flPLISENSRecommended minimum measuring range (bar), depending on the type of the set: pressure measuring device - diaphragm seal Pressure measuring device * The ranges given in the table for the smart transmitters should be taken as set ranges. Recommendations The essential metrological problem at diaphragm seals operational use is an absolute thermal zero error, resulting from the thermal expansion of the manometer liquid. The expansion effect must be compensated for with the separating diaphragm flexibility. To minimise this effect, it is advisable to: - use capillaries as short as possible,...
