9801.001 - 5 digit optical
Digitaker 9801.001 is a microcomputer based digital tachometer for rotational speed measurements, particularly suitable in application where a phisical contact with the moving part cannot be obtained and braking force cannot be applied. Digitaker has a measuring range of 2.0 to 100,000 r.p.m. with automatic decimal point selection in order to ensure a high degree of accuracy. Digitaker is provided with an auxiliary input for an optional external sensor. By inserting the 8830.001 contact sensor, linear speed measurements can be made.
