Electronic pressure transducer with output display

Pressure switch

The invention relates to a pressure gauge having a cylindrical housing to which a bushing is fixed, which penetrates the housing. The pressure gauge is furthermore provided with a pressure sensor together with an allocated electronic evaluation unit, said sensor is operatively connected to a pressure port coaxially positioned to the longitudinal axis of the housing. A turnable adjustment pin to engage with an adjustment device of the electronic evaluation unit in the pressure gauge is accommodated in the bushing in a liquid-proof manner, and is equipped with holding means by means of which it is undetachably secured to the bushing.

The invention relates to a device (20) for a unipolarly operated component (9) capable of storing energy. This device (20) can be applied, for example, in an asymmetrical half bridge circuit (1). It compensates the dc magnetic flux which originates due to the unipolar operation and, hence permits making relatively small in size the component (9) capable of storing energy. Using a current converter (25, 32) with suitable winding ratio as an automatic and load-dependent compensation device, moreover, permits very flexible adaptation to load changes. Such adaptation is, in particular, required when very high pulsating current occurs on the primary side with simultaneous secondary no-load operation.
