ED-510XL
PORTABLE EDDY CURRENT INSTRUMENT
EQUIPMENT SPECIFICATION ES-108
1.0 Description
1.1 The Model ED-510XL is a
portable, compact, self-contained, electronic instrument, which offers high
sensitivity, versatility, and simplicity of operation. A continuously variable frequency control
tunes an oscillator, which drives a bridge circuit, one leg of which contains
the test probe or coil.
1.2 The instrument will locate surface and
near-surface discontinuities in nonmagnetic materials and surface defects in
magnetic materials where permeability is relatively constant throughout the test area. The ED-510XL will sort both classes of materials according to
such properties as hardness, alloy type, carbon content, heat treat condition,
tensile strength, and grain structure where these relate to changes in the
magnetic and electrical characteristics of the test part. Also, it will measure coating thickness and
relative conductivity.
2.0 Mechanical and Construction
2.1 Dimensions: Hand Held
Unit -
3.5” (8.9 cm) x 7.1” (18 cm) x 1.9” (4.8 cm) high
Carrying
Case -
12” (30.5 cm) x 8” (20.3 cm) x 3.5” (8.9 cm)
2.2 Weight: Overall (unit
with carrying case) - 2.2 lb (1 kg)
Hand Held Unit with
Probe - .8 lb (1.8 kg)
2.3 Meter: 2.5” (6.4 cm) wide,
Scale numbered from 0 to 500 in 50 divisions.
2.4 The instrument is housed in
a lightweight, impact resistant case.
The carrying case is designed to protect the unit and accessories during
shipping and when not in use. The foam
cutouts are for the unit itself, probe, test block, and operation manual.
3.0 Electrical and Performance
3.1 The frequency range is variable from 55 kHz to 220 kHz.
3.2 The instrument is powered by a single 9-volt alkaline battery.
3.3 Probes are interchangeable
with any of the absolute probes designed for the ED-250 and ED-530. This includes surface probes, pencil probes,
bolt hole probes and many custom probes designed with the same general coil.
3.4 The instrument is of
solid-state design and utilizes integrated circuits. There are no user serviceable parts or components inside. All service work should be performed by a qualified
electronic technician.
4.0 Operation
4.1 The “LIFT-OFF” control is a
single-turn potentiometer. It provides
a continuously variable frequency range of 55 kHz to 220 kHz to select the
proper operating frequency for lift-off compensation.
4.2 The “BALANCE” control is a
single-turn potentiometer. The control
adapts the probe used to the bridge
circuit and is used to position the meter pointer on the scale.
4.3 The “SENSITIVITY” control is
a single turn potentiometer used to set the sensitivity level of the
instrument. Maximum sensitivity is
obtained with this control set fully up.
4.4 The “POWER” switch provides power to the instrument. Access to the battery is on the back of the
instrument.
4.5 The “PROBE” is a BNC type connector to connect the probe to the
instrument.
