The Brüel&Kjær Photoelectric Tachometer
Probe MM 0024 is especially
designed for remote tuning and
triggering of vibration measurement
and balancing instrumentation in
synchronism with rotating or reciprocating
machine parts. It is ideal for
use with the Brüel&Kjær Tracking
Filter Type 1623, Vibration Analyzer
Type 2515, Portable Balancing Sets
Types 3517 and 3537 and Stroboscopes
Types 4912 and 4913*, all of
which include a combined trigger input
and power socket which accepts
the cable from the MM 0024 directly.
The MM0024 connected with the
QA0137 has the advantage that it
may be located any distance between
50 and approximately 800 mm from
the subject to be investigated, thus
safely separating the Probe from possible
contact with moving parts or an
otherwise hazardous environment.
The light alloy casing of the Probe
contains both a transmitter and receiver
of infra-red radiation. The DC
power supply to the transmitter and
the output pulses from the receiver
are conveyed to and from the Probe
via a double shielded BNT socket at
the rear of its housing (Fig. 1). A 3m
long cable AO0158, terminated with
* MM0024 is only suitable for use with the
Time Delay and Slow Motion modes of the
Stroboscope Type 4913 if the Probe is shielded
against the Stroboscope’s flash
matching connectors, is supplied
which facilitates direct connection to
the Brüel&Kjær instruments Type
1623, 2515, 2976 (included with
Types 3517 and 3537), 4912, 4913
and 2523.
Use of the Probe is very straightforward.
It is mounted on a convenient
static part of the machine using
a magnetic clamp, or a suitable
bracket. Alternatively, a camera tripod
with standard 1/4²  UNC (DIN
