Basic principles of tachometers
General
Tachometers can be used to measure speeds (of linear or rotary movement), rates (per minute or per hour), or rates of flow (volumetric, etc.).
Pulses are fed to the tachometer at the frequency to be measured. A
scale factor is applied to produce readings of the desired type (linear
speeds, flow rates, etc.).
Crouzet/Syrelec tachometers operate on 2 different principles :
1 - The fixed time base principle, and
2 - The reciprocal principle
1 - Principle of the fixed time base tachometer
The tachometer totals the number of pulses received during a fixed period of time known as the time base. At the end of this period, a value for
the frequency measured is shown on the display.
The time base can be set at the time of installation. It is calculated from
the formula shown below, where :
B : is the time base being calculated,
: is the number of pulses per revolution,
N
d
: is the number of revolutions per minute, and
N
t
V : is the value that will appear on the display.
The time base is given by :
Vx60
B=
Nt x Nd
The parameters which govern this tachometer are the following :
■ the sampling time (T
■ the time limit for measurement (T
TR
TL

r

)
L
itted by the sensor
m
Measurement ends at the rising edge of the first pulse after Tr. If no
pulse is received after T, the system waits until the time limit T
shows zero on the display.
and then
L
If the frequency of the signal is low, conditions are as shown below :
Tr
T
8
Once the time base has been calculated, it is set by means of DIP
switches (or changeover switches) situated on the unit.
As an example:
Assume a sensor emits 8 pulses per revolution. What you want to see
on the display is a speed in revs per minute.The maximum this speed
can be is 2000 rpm.
= 8
N
d
N
= 2000
t
V = N
(since what you want displayed is a speed in rpm).
t
2000 x60
B=
2000x8
= 7,5 secondes
Fixed time base tachometers are useful for high speeds but, if the accuracy obtained is to be good, it is essential for the number of pulses per
revolution to be high.
To overcome this drawback, Crouzet Automation can supply reciprocal
tachometers. These need only a single pulse per revolution and are able
to measure both high and low speeds.
2 - Principle of the reciprocal tachometer
This tachometer measures the intervals between n count pulses
(the period) and then performs the calculation
1
f=
T
to obtain a frequency.
Enables end of measurement
The interval between 2 rising edges is very much longer than Tr.
The tachometer displays 0 until time T, at which it displays the new value.
