The robust Type 4520A for measuring torque on rotating shafts offers particularly good value for money and is recommended primarily as an entry-level solution for torque measurement. Frequency modulation is used to transmit the torque signal from the rotating shaft without contact and convert it into an analog signal. The speed signal at 60 pulses/rev. is available as TTL signal level. An external electrical control input is provided as standard.
