WIKA Model PG43SA-S Hygienic Diaphragm Pressure Gauge

Description

WIKA Model PG43SA-S Hygienic Diaphragm Pressure Gauge Technical Data and Engineering Selection Guide

WIKA Model PG43SA-S Hygienic Diaphragm Pressure Gauge is supplied by SANTAN for replacement, new projects and complete model-code review. The verified product-family information below supports preliminary selection, installation planning and quotation preparation.

Verified Product-Family Specifications

Measurement principle	Purely mechanical diaphragm pressure transmission with local indication
Process interface	Flush-welded diaphragm with aseptic connection options
Media	Gases, vapour, liquids, pastes, powders and crystallising media, compatibility dependent
Hygienic operation	Suitable for CIP, SIP and wash-down; autoclavable version available
Contamination control	Dry measuring cell eliminates transmission-fluid contamination risk
Operation	Power-independent display with accessible zero-point adjustment
Compliance	Third-party verified to the 3-A Sanitary Standard for the stated model
Documentation	Material 3.1/2.2 and other GMP-oriented certificates are available by order

Published values describe the product family and remain configuration dependent. Final range, accuracy, materials, pressure or temperature limits, process connection, output, approvals and accessories must be checked against the selected WIKA order code and current data sheet.

Best-Fit Application

Use the PG43SA-S on pharmaceutical, biotechnology, food and beverage equipment that needs a visible local pressure or vacuum indication without external power. Typical locations include pipelines, fermenters, bioreactors, clean-steam systems and portable tanks.

Selection and Installation Notes

Match the hygienic connection to the existing standard and gasket system. Confirm diaphragm material, surface finish, cleaning chemicals, SIP/autoclave temperature, pressure/vacuum range, wash-down ingress requirement and documentation package. A flush diaphragm avoids dead spaces only when the mating connection is correctly installed.

Quotation and Selection Data Required

Measurement	Pressure/vacuum range, normal value, overpressure and required indication accuracy
Process	Medium, viscosity, solids, operating/design temperature and cleaning conditions
Mechanical	Process connection, dial size, mounting orientation and available installation space
Materials	Wetted materials, seal/elastomer requirements and corrosion compatibility
Electrical	If applicable: output signal, supply, cable entry, contact or hazardous-area requirement
Compliance	Hygienic, material, calibration, safety, inspection and project documentation needs
