摘要
The invention describes a field device (1) for use in hygienic applications in process and automation technology, which, in so doing, comprises at least one sensor element (2), at least one electric circuit (3), at least one heating element (4), at least one housing (5), which has an outer side (6) and an inner side (7) and in which at least the sensor element (2), the electric circuit (3) and the heating element (4) are arranged and attached, and an external energy supply unit (11), wherein the field device has two connection pins (8), to which the sensor element (2) and the electric circuit (3) are connected and by means of which there is an electrical connection with the external power supply (11), as a result of which a first current loop (12) is formed, and wherein a second current loop (13) is provided, the latter being arranged in such a way that the heating element (4) is in electrical contact with the external energy unit (11) by way of one of the two connection pins (8) and the third connection pin (9), as a result of which the second current loop (13) forms a parallel circuit with the first current loop (12); and moreover describes a method for producing such a field device (1).
