ABSTRACT:
An enclosure for a transmitter, particularly a pressure transmitter, comprising an upper part containing connection terminals and an outer enclosure connected with the upper part. A printed circuit board is mounted in the chamber formed by the upper part and the outer enclosure. To increase the immunity of the pressure transmitter from electrical noise, an inner conducting cylinder is used, the cylinder being fixed by a pressure fitting with the outer enclosure. At the same time stampings in the inner cylinder fix the printed circuit board and create earth connection from the printed circuit board via the inner cylinder to the outer enclosure. Besides improving the noise immunity, the invention simplifies assembly of the transmitter and increases mechanical strength, including resistance towards turning and tilting torques.
