Digital Tachometer
TM-3100 series |
|
|
 |
TM-3100 series is a new model of digital tachometer
which responds to changes in diverse measurement objects
by adding function in order to match your application.
The each model of TM-3100 series has the most
fundamental function in rotational measurement (display
of rotation speed, BCD output, analog output or
comparator output) and can be customized by adding
optional cards.
The fluorescent display tube of TM-3100 series greatly
improves stability and readability instead of using LED
as old models. |

Maximum number of sections: 48 sections
Memory mode: Ring buffer mode or memory full mode
*Ring buffer mode: Delete section memory in order of
the oldest one and continue to store the latest section
data when number of section data exceeds 48.
*Memory full mode: The storing of the data will be
completed after the data for 48 sections are stored. |
|
Acceleration calculation function |
The acceleration data is obtained at every 1 second by
the calculation of rotation speed, circumferential speed
and moving speed.
