Measurement instrument

In a two-conductor technology circuit the use of certain ASIC components is made possible which, for instance, allow for the supply of contact-free rotational angle sensors, although said ASIC components have a high current consumption.

Measuring instrument in two-conductor technology

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.

Remote transmitter for analogue gauges

The pressure transducer comprises a pressure connection (2) and a tube-shaped housing (22) that is securely attached at its lower end section (24) to the pressure connection. Arranged in the interior of the housing (22) are a pressure sensor (6) carried by the pressure connection (2) and a circuit arrangement (8). An interface module (18) is attached at the upper end section (26) of the housing (22), the connection between the interface module (18) and the upper end section (26) being effected by means of a locking ring (32) that is locked to the housing (22) and that is either integral with the interface module (18) or that carries a union nut (46) that secures the interface module (18) to the locking ring (32). During manufacture of the pressure transformer, the housing (22) is attached to the pressure connection (2) before the interface module (18) is brought into electrical contact with the circuit arrangement (8) and before it is connected mechanically to the housing (22). This makes it possible to adjust the pressure transducer prior to attaching the interface module (18). Furthermore, the pressure transducer can be provided with a plurality of different interface modules without this resulting in disadvantages during manufacture of the pressure transducer. (FIG. 1)
