In a method for converting an analogue measurement indication into electric signals, the angle of rotation of the pointer of an analogue display is contact free detected and converted into a proportional electrical output signal. This is achieved by using an application-specific integrated circuit having a Hall sensor which can detect the magnetic flux density parallel to the surface of the integrated circuit.

In the manufacture of a measuring device for pressure or temperature, which exhibits a measuring element, a pointer mechanism, a face dial and a pointer shaft one measures the deflections associated with the shape change of the measuring element for at least three various values of the parameter being measured, and based on the pairs of values consisting of magnitude of the parameter measured and the deflection a set of instructions for arranging the scale markings on the face dial is determined. The scale is inscribed on the face dial according to these instructions by means of a laser printing tool. In this manner the scale can be fitted to the measuring device surveyed and the linearity errors of the indicator can be kept small.

A pressure gauge housing (3) made of a synthetic material and having O-ring sealing seat (1) for the spring carrier (42). The housing features a protruding edge (2) which is molded on the front side on the cup-shaped housing (3). The O-ring sealing seat (1) is shaped out of the housing circumference so that it will close flush with the edge (2).
