125mm Dial 11 bar Diaphragm Seal Pressure Gauge with Capillary
Description
Pressure gauges with a diameter between 40 and 250 mm with an
internal baffle wall are of the M11 type and also have a blow-out
back. A baffle wall is a solid plate which is located between the
Bourdon tube and the window. Upon failure of the Bourdon tube, the
baffle wall will protect the window from being pressurized and the
build-up pressure will blow away the blow-out back.
Applications
Hygienic pressure measurement in sanitary applications for the
pharmaceutical, biotechnology, food and beverage industries
Mechanical pressure display on pipelines, fermenters, bioreactors
and vessels
Pressure/vacuum monitoring during cleaning, sterilisation, pressure
testing
For gases, compressed air, vapour; liquid, pasty, powdery and
crystallising media
Special features
Safety via mechanical pressure transmission
Case and wetted parts in hygienic design
Suitable for SIP and CIP, autoclavable version available
Easy zero point setting
High overload safety
