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
