Ono Sokki TM-3100 Series Digital Tachometer

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.

Measurement accuracy
Display value × (±0.01 %) within ±1 count

*The display value indicates the count value except the decimal point.

Auto zero function
The display value becomes zero with no signal input for the setup time in advance.Selectable from below;
OFF (11 s), 0.5 s, 1.0 s, 2.0 s, 3.0 s, 4.0 s, 5.0 s, 6.0 s, 7.0 s, 8.0 s, 9.0 s, 10.0 s
Rapid deceleration follow-up function
If an input signal rapidly decreases and there is no signal input to tachometer approx. 1 second or more, measurement automatically decelerates with this function and then zeroed in approx. 11 seconds later.

OFF (factory setting), 2, 4, 8, 16, 32, 64, 128

*Analog output by TM-3130/0330 is obtained by the processing of
moving average with the calculation at every 10 ms.
