The land range facility generally mainly consist of the following:-
Stainless steel railway with trolley and cable winch.
Deperming coil, consist of either smaller portable coils with a hole size of approximate 75cm or of bigger component the coil will be winded directly on the components.
Zero-field coils (H,Z) are situated in the middle of the range, (where also the magnetometer probes are located in bore holes).
Magnetometer probes. mounted in bore holes, which are connected to magnetometer electronics and compensators situated in the range office.
Analysis capability of the land range lack the use of data acquisition and data analysis tools. only analogue high speed channel writers exist. All analysis work must therefore be done manually and very labour intensive with paper and rulers, this work method was very common until the end of 1970-ties before computerized data acquisition units became more commonly available on the market.
Land Range Deperming (Propeller, Genset, Shaft)
The land range is located in N-S direction and located with office building which had offices, training class rooms and separated laboratory office with the magnetometer electronic equipment’s. A separate electric house facility is located beside the land range. The electric house contains all electric generators, high precision current shunt etc. for the land range deperming function.
