BALANCING MACHINES
Vibration monitoring equipment,
TM1
single/dual channel
Function
The TM1 equipment continuously measures the
vibrations of rotating machines by supplying analog
outputs (for interfaces to PLC or DCS) or digital
outputs (alarm and trip contacts) with the display on
a digital readout of the found value. The equipment
can be connected to other instruments (max. 32)
via serial line RS485 or to a PC (through appropriate
interface) for setting and reading the stored data by
the various measuring parameters.
Main characteristics
The TM1 instrument has been designed and
implemented with the latest digital technologies
which have allowed to improve the ß exibility
and performance of the system, by reducing its
overall dimensions and simplifying the procedures
for installation, setting and modiÞ cation of all the
operating parameters.
The instrument can be interfaced to 1 or 2 sensors
(velocity transducers or acceleration transducers)
besides with two phase reference transducers.
Digital readout of the vibration value allows the
operator to have an immediate check of the vibratory
state of the machine during set-up operations.
The control panel is provided with various buttons
Typical applications
Testing of the vibration of one or two channels
of any type of rotating machine (motors, fans,
compressors, turbines, pumps, etc.). It is normally
installed near the machine and performs all the
functions required for protection and monitoring:
measurement, protection, alarm signalling,
interfaceability with supervisory system, selfdiagnostics.
for presetting the operating parameters of
the instrument (selection of: measuring unit,
alarm thresholds, alarm time delay, threshold
multiplier, by-pass) as well as LED’s for displaying
the status regarding alarm, self-diagnostics
and BNC sockets for connection to a vibration
analyzer. The instrument is also provided with
a serial link RS485 for transferring stored data
and settings of all operating parameters of the
instrument by a PC.
The TM1 equipment can be installed in an
electrical cabinet (Þ xing on Din rail) or inside
a junction box positioned next to the machine
being monitored
