VTI21 Smart Sensor
Sensor for high-speed sampling
This specialist device combines analogue sensors with digital signal processing to analyse the performance of many track-circuit types, including AC, audio-frequency, and HVI.
The on-board processor calculates key performance metrics of complex input signals, which are reported to a datalogger either over RS485 serial, or a low- frequency analogue output.
