HIV (human immunodeficiency virus) is a virus that attacks the immune system, the body's natural defense system. Without a strong immune system, the body has trouble fighting off disease.
Servo-Tek Distributor: DC Tachometer Generators. A Servo-Tek DC tachometer generator provides a convenient and economical means of converting rotational speed into an isolated analog voltage signal suitable for remote indication and control. Combining high accuracy with low driving torque, Servo-Tek tach generators are ideal for use in servo systems. Tach Generators are particularly suited to application in precision integrators and velocity servos, both of which require a highly linear speed/voltage relationships with minimum ripple.
Okay, then let's throw one more thing in for tach use. When the circuit is broken (distributor points open) for the coil to fire, not only does the (-) terminal go positive, but the effect of coil firing is a 'ringing' through the windings, causing small higher voltage pulses on the order of about 100 to 400 volts.
