A tachometer sensor 4 is used in the magneto tachometer designed for continuous distance measurement engine speed to vehicle systems and special purpose machines.
D4 tachometer sensor are three - phase alternator with permanent - magnet rotor.
D4 sensor is designed to work with a single meter.
Specifications tachometer sensor D - 4:
A tachometer sensor 4 maintains the vibrational load to the acceleration of 100 m / s 2 and a frequency of 10 to 200 Hz.
The voltage between each two phases of the sensor D - 4, loaded with one meter at 3000 rev / min on a scale meter 1: 2, or 750 rev / min for meter scale by a factor of 2: 1 after working for one minute, in the range of 10 5 to 12.5 V.
The weight sensor is not more than 0.98 kg.
