Abtus ABT 4550 Series Kullanım Kılavuzu
2.0 Overview
Abtus track gauges have been designed with a sprung gauging foot, with all measurements
displayed on the useable end of the gauge, ensuring improved repeatability and accuracy of
measurements, whilst minimising potential for user error.
Constructed from hard-wearing glass reinforced plastic (GRP) and polyvinyl chloride (PVC),
the ABT4550 is electrically non-conductive and will not interfere with the track signalling circuit.
These therefore are suitable for use in areas of 3rd and 4th rail electrification. The ABT4550
is available in both imperial and metric versions for multiple track widths. The standard
mushrooms measure 14mm below the top of the rail (TOR), alternative P-points should be
specified when an order is placed.
Super-Elevation is measured electronically and is shown on an LCD display. The expected
battery-life for normal, average usage is 12 months. The unit is powered by 2 standard 9v PP3
battery which can be easily by replaced by the operator when required.
Track Gauge is measured mechanically with readings displayed through a clear polycarbonate
window on a linear scale.
