Electronical tachometer
| Application | |||
| The instrument measures the revolution number of engine crankshaft of vehicles. | |||
| Description | |||
The instrument is suitable for measuring the revolution number of motor vehicles having an electrical network supplied by an alternator. The instrument consists of a movement built into an internal-illumination metall case coated against corrosion. The signal series received from the 'W' point of the alternator will be processed by the IC signal transformer unit of the instrument for the moving-coil movement. |
