Universal Engine Tachometer Ct-6520

UNIVERSAL ENGINE TACHOMETER CT-6520

Provides error-free digital rpm measurements and, when used in combination with Ono Sokki detectors, can be used to make rpm measure- ments on virtually any engine type. Sensor selection enables rpm me

The CT-6520 Universal Engine Tachom- eter uses a multiplier circuit to both reduce measurements time and improve measurement accuracy. An input pulse selection switch is used to set the number of pulses produced by the detector for each revolution, enabling measurement on virtually any engine type. In addition, the CT-6520 can be used for rpm measurements on other rotating bodies as well.

Major Featuresع ٨Digital and analog outputs and puIse outputs are ٨A selector switch can be used to specify the type of engine to be measured, optimizing measurement provided as standard. .٨CE marking compatible .conditions for the Ono Sokki detector to be used ,٨Both AC and DC-powered operation are possible ٨Used in combination with various detectors, rpm measurements are possible on 2/4-cycle engines making the CT-6520 highly useful in both indoor and having from one to eight cylinders. vehicle-mounted applications. .٨Two speed levels can be perset for comparison ٨The number of input pulses per revolution can be set in the range 0.5 to 199.5 P/R in 0.5 P/R steps.
