Abstract
An arrangement for controlling the electric energy supply rate to an electroplating installation includes a positionally adjustable actuating member connected to a carrier which supports workpieces to be electroplated in an electroplating vat, and a sensor mounted on the vat and operative for detecting the extent of positional adjustment of the actuating member and generating a signal proportionate thereto. The signal is then transmitted to a source of direct electric current to be used thereat for controlling the output rate of the source. The actuating member is a setting screw which is threaded into a sleeve which, in turn, is mounted on a bracket rigidly connected to the carrier, while the sensor includes a housing rigidly mounted on a lug of the vat, and a potentiometer accommodated in the housing and having a detecting rod which extends beyond the housing and into the path of displacement of the setting screw. The housing is sealingly closed by a sealing cable connector, on the one hand, and by a bellows-shaped protective member sealingly connected to the housing and surrounding the detecting rod of the potentiometer, on the other hand. A spring urges the detecting rod toward…
