The FerroTec FT 10 helps you safely and reliably locate concealed shaft covers, sliding rods and caps, as well as pavement markers and other objects. The only requirement is that they are made of iron, cast iron or steel. The ergonomic design, convenient operation and precise measuring technology make your work fast and easy.
Objects containing iron cause changes in the earth’s magnetic field which can be picked up by the two magnetically sensitive sensors in the FerroTec FT 10 (fluxgate magnetometers) and converted to an acoustic signal. In addition, the display shows you getting close to the object you are looking for. The closer you are to the object, the stronger the signal. At maximum signal strength, the FerroTec FT 10 is exactly above the object.
Principle of Operation of the FerroTec FT10 Lost Manhole and Valve Locator
Buried iron objects disturb the earth’s magnetic fields which surround them. The magnetic field at the end of the FT10’s sensor rod, sensor A, is not the same as at sensor B; it is the difference in these levels that is measured and allows the FerroTec FT10 to locate objects that are buried far deeper than a conventional metal detector can.
The FerroTec FT10 offers outstanding performance with detection of objects down to 15m (objects with mass of 100kg).
Detection of cast iron pipes is even possible particularly if they run north south.
There are two ways of viewing the FT10’s signal:
A circle increases in size as you get closer to the target object. Simultaneously a numerical value is displayed either as a positive or a negative value dependent on the object’s orientation to the earth’s magnetic field. This information is useful as it can indicate the orientation/shape of the cover or spindle or other object in the ground.
50 Hz alternating current (power cables) are indicated with signal strength. This can alert you to the presence of live electric cables.*
Bar Graph Display
A Bar graph increases or decreases from the centre zero point depending on the orientation of the object to the earth’s magnetic field.
A numerical value is displayed – the higher the value (left or right) the closer you are to the object,
In the Bar Graph Display mode 50 Hz alternating field (power cables) is indicated . This can alert you to the presence of live electric cables.*
