Fischer Germany Pressure Gauge MA13 series
Fischer offer MA13 series The pressure gauge MA13 for overpressure and vacuum meets the high technical requirements of corrosion-resistance and interference immunity. It is used for liquid and gaseous media, except those having a high viscosity or are liable to crystalize. Construction and Operation
The measure pressure is transferred into the measuring element via the connection thread. By means of the pressure admission an elastic deformation occurs, leading to a movement of the measuring element. This movement is converted into a pressure-proportional pointer deflection via the motion work. The measuring element and the connection thread is one construction, together with the motion work and the scale. Therefore the measuring system is autonomical against forces acting on the case. Internal spring stops limit the pointer deflection up to 270 angular degrees. Regulations for prevention of accidents and div. laws require measuring instruments for special processes acc. to manifold safeguards. The type ’’bayonetcase acc. to DIN 16006“ meets these requirements disposing of following features:
- blow-out of case back wall,
- front window of security laminated glass,
- securityagainst fracture via separating wall between measuring element and dial.

Electrical accessories acc. to datasheet KE...
Liquid filling In case of aggravated operating conditions like vibrations and pressure oscillations, or against condensation in case of outdoor-installation, the case can be filled with damping liquid. Marking pointer Adjustable pointer for signal marking behind the window.
Drag pointer The drag pointer is carried by the measuring indicator.Between the two pointers does not exist a fixed connection, e.g. once reached maximum values are accumulated. Via an adjusting knob in the window the drag pointer can be readjusted.
