"MA 13Bourdon Tube Pressure Gauge (for chemical use)

Application The pressure gauge MA13 for overpres-sure and vacuum meets the high techni-cal requirements of corrosion-resistanceand interference immunity. It is used for
liquid and gaseous media, except thosehaving a high viscosity or are liable tocrystalize. Application Fields Chemical industriesՕMaterials processing
Pneumatic systems
ՕMachinery and terotechnology
Environmental technology Construction and Operation The measure pressure is transferredinto the measuring element via the con-nection thread. By means of the pressu-re admission an elastic deformationoccurs, leading to a movement of themeasuring element. This movement is converted into a pres-sure-proportional pointer deflection viathe motion work. The measuring ele-ment and the connection thread is oneconstruction, together with the motionwork and the scale. Therefore themeasuring system is autonomicalagainst forces acting on the case. Internal spring stops limit the pointer de-flection up to 270 angular degrees. Regulations for prevention of accidentsand div. laws require measuring instru-
ments for special processes acc. to ma-nifold safeguards. The type Ւbayonet-case acc. to DIN 16006ғ meets these re-quirements disposing of following fea-tures: blow-out of case back wall, front-window of security laminated glass, se-
curity against fracture via separatingwall between measuring element and di-al. >
