AbstractA transducer having an explosion-proof housing with a divider forming two compartments, and the divider having formed therein a well. A magnet and flapper arm arrangement is suspended within the well. A coil winding is fixed in the other compartment around the well so that a magnetic field generated thereby influences the pivotal position of the magnet. Set screws adjustable in the bottom of the well are effective to preset a rest position of the magnet.
