The TM-2100 series are compact and light-weight digital tachometers, which size conforms to DIN standard (96 x 48mm).
They have a sudden deceleration following function and can indicate revolutions following sudden stops. These tachometers can measure and monitor revolution, line speed, flow rate, etc. when the unit converting function of the built-in microcomputer is used. This series are available in four types for different output patterns.

 

 

TM-2110 Basic type
 
TM-2120 with BCD output
suitable to output to computer and sequencer.
TM-2130 with analog output
suitable to output to recording equipment.
TM-2140 with comparator function.
Upper and lower limits can be set. Applicable to alarm
