POWER SHIELD OVERVIEW
The Digimatic detects material by radiating a high frequency (RF) signal from the probe. The advanced
electronics of the Digimatic use this signal to measure the capacitance inside the vessel with respect to
ground and thus indicate when material has reached the Digimatic probe.
The power shield creates a barrier and enables the unit to ignore a certain amount of material built up on
the probe, helping to prevent false readings. The Digimatic’s standard power shield is 121mm in length,
with options for a 160mm and 221mm available on request. Other specific lengths may be available.
Please contact us for more information.
The standard (121 mm) power shield can be used with walls that are up to 115 mm (4.5 inches) thick.
Installation through thick concrete silos only requires a 25.4 mm (1 inch) diameter hole for probe
insertion.
NOTE
The actual amount of material build up that the Digimatic is able to ignore is dependant upon several
factors, including the density of the material, the moisture content of the material and the type/style of
the vessel.
