Introducing the VTi21 Smart Sensor
The VTI21 has been designed for the monitoring of railway assets that require high-speed sampling and/or multiple input
channels. The VTI21 contains an on-board microprocessor that takes raw incoming waveforms and derives computed values
that are most relevant from a condition based maintenance perspective. The VTI21 can derive many output parameters from
the source waveforms and all of these parameters can be output over the RS485 data link to a connected MPEC data logger.
Master-Slave Operation:
Connect up to 7 x VTi21 per SA380TX
4-20mA Operation:
Point-to-Point Operation via Industry

AC Vane Relay
Perfect for determining the true instantaneous torque of AC vane relays, plus phase relationship,
RMS coil currents and waveform quality outputs.
EbiTrack / TI21
Monitor two track circuits, measuring quantities such as sideband ratio, average current and centre
frequency.
FS2500 / FS2600
Monitor two track circuits, measuring quantities such as sideband currents, average current inband and out-of-band RMS currents and spectral content.
High Voltage Impulse
Monitor two track circuits, measuring average current, duty cycle, frequency and pulsed power.
AC Switch Machine
General Purpose AC
Monitoring
Monitor single phase or three phase AC switch machines. The VTi21 will report waveforms for all
phases and provide direction of switch movement.
Simply monitor the AC draw of any two conductors in any circuit of interest.
