VDT monitors
VDT are units for safety monitoring of case vibration, axial
displacement, relative shaft vibration, temperature and
speed rotation measurement
VDT monitors
• VDT02-A (dual ch., vibration, BC, T)
• VDT02-AB (dual ch., vibration, BC, T, RPM, balancing)
• VDT02-W (dual ch., relative displacement, T)
• VDT02-APS (dual ch., relative shaft vibration, T)
• VDT921 (VC-920 equivalent)
• VDTB01 (VC-920 equivalent, T, CAN/RS485)
• VDT922 (doubled (redundant) single channel, BC, T,
CAN/RS485)
SVA400 – portable digital vibroanalyser
VDT monitors
All VDT monitors
are based on the
same hardware
platform. Dedicated
functionality is
performed by
firmware.

Sensors
• AAT81
– Double accelerometer with temperature sensor
– Sensitivity 100mV/g (both sensors)
(sensitivity can be changed according customers
requirements)
– Temperature range 0-130°C +-1%
• ASW – accelerometer with temerature sensor
• Others – Other designs with or without temperature
sensor. Usualy with 100mV/g sensitivity or other if
required.
