FT-2500
Advanced Tachometer

Selectable contents vary depending on the rotational condition. There are 5 kinds of measurement algorithms.
MODE Measurement algorithm
A Steady rotation Maximum power spectrum peak detection method
B measurement mode Peak-interval mode method
C Acceleration/deceleration Multi-order peak followup method
D rotation measurement Maximum power spectrum peak followup method
Emode Specific power spectrum peak followup method
Rotational speed candidate selection function
Calculation is performed using the
frequency of the power spectrum's
maximum peak. Measurement is
usually performed in this mode.
The frequency intervals of the each order component in the
rotation are sought sequentially. The most often appeared
frequency interval is judged to be the first-order component of the
rotational speed in order to fix the rotational speed. This is an
effective method when the first-order peak is unstable.

• In C,D, and E mode, the FT-2500 follows up the acceleration/deceleration condition owing to the
internal high speed processing function.
• In C mode, the FT-2500 predicts the peak value which it should be and calculates the rotational
speed even if the maximum peak has been lost.
• In E mode of rotational speed candidate selection, suitable rotational speed can be selected
from maximum of 8 frequency peaks.

When the amplitude of rotational signal
is not stable and some of the pulse
signals cannot be detected, the
rotational speed is calculated lower than
it should be.
When the electrical noise is contained in
the rotational signal, the rotational
speed is calculated higher than it should
be owing to the malfunction by noise.

No rotational pulse signal is required for a measurement. The rotational speed is
calculated from the frequency signal of light, magnetism, vibration, and sound.
The FT-2500 is an advanced tachometer which measures the rotational speed by the Fast Fourier Transform (FFT)
calculation. Moreover, the FT-2500 can measure the rotational speed from frequency signal of sound, vibration or the
like even though the rotating shaft is not accessible. The FT-2500 allows versatile rotational speed measurements such
as the steady rotation of motor and acceleration/deceleration rotational speed of engine.
• The reflective marks or special machining is not needed to
attach the sensor.
• Because the rotational speed measurement can be
performed easily from the frequency signal of sound or
vibration, no special machining to rotating shaft is
required.
• The measurement under the condition of the change or
acceleration/deceleration in the rotational speed is
available. (When the acceleration/deceleration rotation
measurement mode is selected.)
• Provides rotating direction determination function. (When
the FT-0501 DC Motor Rotation Detector is used.)
• Easy to read fluorescent display.
• Provides both the analog and pulse outputs.
• Ethernet communication function can be added as an
option.

Parts list When installing the FT-2500, the following precautions should be taken care of.
Some installation conditions may give adverse influence against the noise tolerance.
• Separate the power supply cable of the FT-2500 from the power line which is connected to high-power
load.
• Be sure to use the power supply cable which is provided as standard accessory.
• Do not arrange the wiring of the FT-2500 cables in parallel or together with the power line.
• Do not extend the sensor signal cable longer than necessary.
• Use cables of 5m or less in length for DIGITAL-I/O and V-OUT.
•Use a shielded cable as the signal cable. In addition, be sure to ground the shielding wire.
•Keep the FT-2500 as far away as possible from devices, which are generating the strong high-frequency
signal or surge.
•Keep the FT-2500 and its cables away from devices, which are generating the strong electric and
magnetic fields.
•Be sure to connect the FT-2500 to protective ground.
•When installing the FT-2500 inside a control or measurement panel, ground the instrument shielding wire
to the panel and also ground the control or measurement panel.
•If it is subject to influences by electrical strong noise or surge, use a surge killer and noise filter inside the
control or measurement panel as shown in the figure left.
*It is requested to wire the signal cable as short as possible. Keep the minus side of the surge killer within
50 cm. Ground both ends of the shielding wires of all input/output signal cables to the ground terminal of

The rotational speed of a DC motor can be measured without attaching the
reflective mark on the surface of the shaft. This example allows the rotational
speed measurement of the fan, which shaft is too thin that reflective mark can
not be attached or optical light can not be reflected straight when optical
sensor is used.
•Easy operation - just input the number of fan blades.
•Non-contact measurement - ideal for inspection line measurement.
Rotational speed measurement of a DC motor
with the micro rotating shaft
It is an example to determine the rotating direction and measure the rotational
speed of a DC motor by using the FT-0501 DC Motor Rotation Detector.
The FT-0501 detects the magnetic flux leakage of a DC motor and extracts a
frequency signal in proportion to the rotational speed. Since the FT-0501 has
two internal coils, a phase shift occurs between the two detected signals.
The rotating direction is then determined by the relationship of these two
phases. This function is very convenient for quality control of small DC
motors, whose rotating directions may be difficult to be determined visually.
Of course, it can measure the rotational speed.
•Rotating direction is also determined by the output of the two-phase signal.
•The output function (semiconductor relay) that determines the rotating direction is
useful for CW/CCW judgment on inspection lines.
Determining of rotating direction and rotational
speed measurement of a general DC motor
With a combination of the FT-2500 and suitable accelerometer, the rotational
speed of a compressor in the refrigerator, vending machine, air conditioner etc,
which shaft is not directly accessible, can be measured easily.
Put an accelerometer (NP-3000 series) on an optional magnet base (NP-0100
or NP-0101) and check the signal at various locations. And then place it at an
optimum position on the compressor.
•Permits easy measurement of compressor shaft’s rotational speed even though a
rotating shaft is not accessible.
•Permits measurement of the rotational speed of a compressor itself and also
which is already built in a final product.
Rotational speed measurement of a compressor
using an accelerometer
Many DC motors are mounted in automobile electrical equipment. The
consumption current of the DC motor pulses in proportion to the number of
poles in the motor. The rotational speed of the DC motor can be accurately
measured by inputting the current signal which is detected by the current
probe sensor to the FT-2500.
This example is ideal for measuring the rotational speed of a stand-alone DC
motor or products (parts) that incorporate motors whose lead wires are
accessible, such as those found in automobile electrical equipment.
Rotational speed measurement of a DC motor
in a fuel pump using a current probe sensor
A pump’s rotational speed is easily measured by monitoring exhaust sound.
The rotating shaft in a pump is generally not exposed externally, making it
difficult to perform measurement of the rotational speed by the ordinary and
conventional pulse detection method. In this example, the sound pressure of
the exhaust sound is detected for the rotational speed measurement with a
microphone.
•Easy operation - just input the number of blades.
•Permits measurement of pump rotations when the rotating shaft is not directly
accessible.
Rotational speed measurement of a pump
using sound pressure
A popular electric toothbrush is operated by converting the rotation of the DC
motor into the vibration. The FT-2500 with FT-0501 detector can measure the
rotational speed by detecting the magnetic flux leaking from the DC motor
which is built in such product.
•The FT-2500 detects the pulsation of the magnetic flux leakage in proportional to
the number of poles of the DC motor which is built in the finished product.
•Provides two steps, upper-/lower-limit comparator output which is ideal for OK,
LOWER, or UPPER determination on inspection lines.
•Permits data management through RS-232C interface.
•Measurement system can be configured at affordable cost.

The FT-2500 can measure the rotational speed of an engine by the sound and
vibration related to the movement of the pistons. It is effective when the
rotational sensor cannot be attached because the engine compartment is
covered.
•Set the number of pulses to match the number of ignition firings per one
crankshaft rotation.
(e.g.) Set at 2 P/R in the case of a four-cylinder engine with four-cycle
Rotational speed measurement of an engine
using a microphone or an accelerometer
The rotational speed of an engine can be measured by clamping a sensor to the
primary low-voltage or secondary high-voltage conductor. Measurement can be
performed simply by inputting the number of ignitions per rotation.
•Set the number of pulses to match the number of ignition firings per one rotation.
(e.g.) In the case of a four-cycle engine
If you perform the measurement on the primary side, set the number of
pulses at half number of cylinders.
If you perform the measurement on the secondary side, set at 0.5P/R
because one pulse is generated per two rotations.
Rotational speed measurement of an engine
using an engine rotational sensor
Connect the sensor to a power outlet in a car or construction machine. With
the FT-2500, you can determine rotational speed of the engine by measuring
the ignition noise from the power outlet. Can be used with both 12 and 24 VDC
batteries.
Rotational speed measurement of an engine
using a cigarette lighter socket sensor
This example shows how to measure the rotational speed of an engine from
muffler’s sound. Since the pulsation component of the engine rotation is
included in the muffler’s sound, the engine's rotational speed can be obtained
by the frequency component of this pulsation.
•Set the number of pulses to match the number of ignition firings per one
crankshaft rotation. Please note, however, that depending on muffler
performance, there may be cases that measurement cannot be performed.
•Muffler’s sound level and engine rotational speed can be measured
simultaneously using the FT-2500 in combination with the LA-3000 series Sound
Level Meter. By using a comparator function of the FT-2500 and an external
control function of the LA-3000 series, you can measure the sound level after
getting the specified rotational speed.
Rotational speed measurement of an engine
from muffler’s sound using a microphone
By detecting magnetic flux change, you can perform the rotational speed
measurement of a motor in a hybrid/electric car or the motor in its air
conditioner. Using the OM-1200, which detects magnetic flux leakage from an
object, you can measure the rotational speed of the motor even if the rotating
shaft is not directly accessible.
Rotational speed measurement of a motor
By the rotational vibration, the FT-2500 can measure the rotational speed of a
motor which is built into the dryer, electric drilling machine or the similar
equipment even though the motor is not accessible.
