TRASDUCER MOUNTING
The calibrator HD2060 presents a at circular steel xing base (see Figure 1), resistant
to abrasions, with a threaded hole in the center UNF 10-32 for the mounting of the
transducers. The fixing base can freely rotate on its housing so as to avoid damage
to the calibrator when mounting the sensors and applying the tightening. To fix the
accelerometer using a screw it’s sufcient a 1-2Nm tightening force, compatible with a
manual operation. For maximum measurements repeatability, the use of a torque wrench
is recommended.
Maximum applicable forces to the xing base are: 30N pressure force, 10N traction force
and 2N transverse force (see picture 2). Applying a load which exceeds specified
limits can permanently damage the HD2060 calibrator.
Fig. 2: maximum load limits for vibrating base
As an alternative to screw mounting, it’s possible to fix the sensor onto vibrating base
using double-sided tape, wax or quick glue; for this can be used the supplied insulated
base HD6245.1 (see picture n.3) to be mounted between vibrating base and transducer. To
avoid an excessive pressure on the vibrating base, we recommend to glue the transducer
on the HD6245.1 adapter before screwing it to the vibrating base.
Fig. 3: Adhesive Mounting
To calibrate axes orthogonal to the mounting axis on triaxial accelerometers, is supplied
the adapter HD2060.20, complete with UNF10-32 dual threading screw to x the adapter
to the mounting base and screw with UNF10-32 threading to x the sensor to the adapter
(see picture n 4).
ORDERING CODES
HD2060: Portable calibrator for acceleration, velocity and displacement transducers.
Double emission frequency 15.915 Hz (amplitudes 1 m/s2 and 0.1 g) and
159.155Hz (amplitudes 10m/s2 and 1g). Backlit LCD display. Power supply with
internal rechargeable battery or external 12Vdc power supply. Includes: support
(HD2060.20) for triaxial accelerometers mounting, rechargeable internal battery
(BAT-40), power supply (SWD10), carrying case and calibration report, HD6245.1
insulated base for adhesive mounting.
Accessories
SWD10: Stabilized power supply 100-240 Vac / 12 Vdc 1 A.
BAT-40: Rechargeable NiMH battery pack 1,2V x 4 .
HD6245.1: Base with integrated UNF 10-32 screw. To be used for adhesive mounting
HD2060.20: Support for the lateral mounting of tri-axial accelerometers with 10-32 UNF
mounting screw
Fig. 4: Use of adapter HD 2060.20
If you use the HD2060.20 adapter to calibrate at 16 Hz perpendicular axis of a triaxial
accelerometer having a mass greater than 30 g, it is necessary to balance the load using
a counterweight equal to that of the transducer to be mounted, as shown in figure 5.
Fig. 5: Use of counterweights
Calibrator must be placed on a flat horizontal surface, possibly free from external
vibrations. In order to check that transmitted vibration level from supporting surface is
negligible it is sufficient, after transducer has been fixed to the mounting base, to verify
that acceleration on the measurement chain with calibrator turned OFF is below 1/5 of
calibration level. For example, if a calibration has to be made at 15,915Hz with 1m/s2
amplitude level, acceleration on the measurement chain when calibrator is OFF should
be less than 0,2m/s2.
During calibration solicitation it’s necessary to avoid unbalances on the base, taking care
of transducer’s connection cable positioning, in order to minimize the transverse load.
Transducer should be mounted so that the load is centered on the base.
BATTERY CHARGE
The battery symbol on the display continuously provides the charge battery status. As
the battery discharges, the symbol “empties”. When the charge is insufcient for correct
device operation , the symbol starts blinking and it will be not possible to activate the
emission of the vibrating base.
In order to charge the batteries, connect the SWD10 power supply to the input plug
positioned on the calibrator’s side. During battery charge, the “CHARGE” red LED is ON.
The LED will turn OFF when the charge is completed. The time necessary for a full charge
is about 4 hours.
Power supply has a dual function: supplies the device and charges the NiMH battery.
When power supply is plugged in, the battery symbol on the display, is substituted by the
symbol of a plug.
In order to preserve over time the battery capacity, it is recommended to make a
complete charge cycle at least one time every two months.
