Drukuj stronęThe DIGIMATIC is a fi xed point Level Controller incorporating a microcomputer which is used to automatically
calibrate the probe to suit the material being detected. Full manual override facilities are included.
The DIGIMATIC employs a power shield to minimise the effect of material adhering to the probe making it
ideal for detecting most materials including sticky or viscous types. It is equally suited to both liquids and
solids. The probe may be a solid rod, metal plate or wire rope. The self contained DIGIMATIC is normally
supplied with a loose probe, available as a stainless steel rod in standard lengths of 100mm, 1 metre or 2
metres, or as a 10 metre wire rope suspension probe and weight.
The probe should be screwed to the DIGIMATIC. Prior to attachment, the probe length can be reduced or
increased, if desired, but see notes a) and b) regarding minimum surface area.
NOTES:-
The DIGIMATIC sensitivity is proportional to the surface area of the probe. When using a 16mm dia. probe the minimum length
to use, for the majority of materials, is 200mm. This should be treated as the minimum if
possible.
If the probe length needs to be reduced to less than 200mm, the surface area should be maintained. This can be achieved by
increasing the diameter, by fitting a metal tube over the probe, or by bending the probe rod. In certain high density materials it
may be possible to reduce the length without compensation.
