Electrical Conductivity Meter
Measurement of Electrical Conductivity is an accurate and repeatable method for checking non-ferrous metals for identity, grade and material conditions. The AutoSigma 3000 gives accurate operation in an easy-to-use package that is both light and rugged.
The AutoSigma 3000 is designed for operator convenience. The lightweight, battery powered unit is easy to carry and easy to hold during inspections. A large character, backlit display makes reading easy even in low light conditions.
The AutoSigma 3000 has two alternative operating frequencies. The 500 kHz frequency allows inspection of thin materials using the standard probe. The 60 kHz setting is the aerospace industry standard.
Low power circuitry gives up to 100 hours of operation from a single set of alkaline batteries, whilst temperature and lift-off compensation ensure the accuracy of each measurement.
Flexibility of operation is also improved with the AutoSigma 3000 - the user can exchange probes in the field, without the need to return the unit to base for probe matching. This system allows the instant replacement of damaged probes, and an easy transfer between the different diameter probes available.
The AutoSigma 3000 has an in-built datalogger facility, allowing the recording of up to 500 readings, the unit can also be connected to a PC for fuller report generation.
The AutoSigma 3000 has many applications within the field of electrical conductivity testing. It is suitable for:
- Alloy identification and verification
- The verification of heat treatment during manufacture and to detect in-service heat damage (e.g. in aircraft)
- The detection of changes in material grade
- Metal sorting
- Determination of the density of powder metal parts
- To measure the electrical conductivity of material (wire, bus bars and conductors) during production and in-service
