Description
The Electronic Fluxmeter EF 14 is
designed to measure the magnetic flux using measuring coils. It comprises a
precise analog integrator of high sensitivity and low drift.
Key
features:
- Microprocessor controlled, easy operation
- Automatic drift correction
- Analog integrator featuring high dynamic range and real analog output
- DC and AC integration
- Fast peak-hold to capture magnetic field pulses
- Complete menu control, the most important functions can directly be accessed
by function keys
- Automatic calculation of measuring results taking into account the coil
parameters
- Directly reading in Volt-Seconds, Weber, Tesla, Gauss or other units
- Memories to store parameters of self-made coils (measuring coil constants,
resistances etc.)
- Convenient input of coil data and limits via the numeric keypad
- Measuring data memory, can store up to 100 measurements
- Automatic coil recognition and instrument configuration for measuring coils
with data memories
- 2 limit comparators with relay outputs for process control
- Compact design
Applications and measuring quantitiesThe EF 14 is applied in the
following areas:
- Quality control of permanent magnets
- Quality control of soft magnetic components
- Quality control of magnet systems (motors, loudspeakers, magnetic clamps,
couplings etc.)
- Materials research
- Development of magnet systems
- Magnet testing
- Magnet sorting
- Material analysis
- Automated testing
- Process control
- ¡¦
The following quantities can be measured with the EF 14 and
appropriate coils:
- Magnetic flux
- Magnetic flux density / induction
- Magnetic field strength
- Magnetic potential / tension
- Magnetic moment
- Magnetic dipole moment
- Magnetic polarization
- ¡¦

Measuring Coils for Connection to Electronic Fluxmeter EF 14A variety
of measuring coils for different applications is available from stock: field
coils (search coil, point coils, thin point coils), moment coils (Helmholtz
coils), potential coils, saturation coils and more. For details on our standard
coil program please consult our coil data sheet.
If you can provide
details on your application we will be happy to assist you in choosing the right
coil. Of course you can also connect self-made coils to the EF 14 or we can
design special coils for you.
Many sample applications and useful hints
can be found in our booklet »Magnetic Measuring Techniques« by Dr. E.
Steingroever and Dr. G. Ross, which can be obtained from us free of charge.
Accessories / Options (not included with instrument)
- RS232 connection cable (3 m)
- USB adapter cable (the RS232 cable is additionally required)
- Data acquisition software (for operation with RS232 interface or USB adapter
cable)
