Information
The VFPF 250 AN 64 AE instrument is a double frequency meter that calculate continually the impulses frequency of the two inputs and displays the two frequencies and their difference and give to the outputs a direct current referred to the frequency showed.
For its characteristics and versatility this instrument can be used as tools counter, speed survey and where is necessary to control linear speed or rotation speed of motor trees with and external systems.
General Features
- Front push-button panel made of polycarbonate.
