FIELD: measuring technique, possibly measuring revolution number of rotary objects. ^ SUBSTANCE: pickup includes body in the form of cylindrical sleeve made of magnetically conducting material, permanent magnet and winding with core placed in body. Permanent magnet is secured at one side to magnetically conducting core and at other side to bottom of sleeve. Open end of sleeve may be sealed by means of magnetically non-conducting lid. Magnetically conducting part of pickup body is covered with protective coating (preventing influence of environment), for example of nickel. ^ EFFECT: enhanced responsibility of pickup due to limited amplitude of output signal. ^ 3 cl, 2 dwg |
