The
SV 111
Vibration Calibrator is designed for in-situ checks
according to ISO 8041-1:2017. In-situ checks are intended for
application in the field prior to and following a measurement or
series of measurements.
The SV 111 is suitable for calibration checks of various of vibration
transducer types at different frequencies from 16 Hz up to 640 Hz.
Depending on the selected frequency you may choose the level of
the calibration from 1 m/s
2
to 10 m/s
2
.
SV 111 has robust casing and built-in rechargeable battery
.
To calibrate or check the measurement system with the SV 84
accelerometer the special SA 154 calibration adapter is needed.
This adapter is optional, not included in the monitoring station
standard set.
2.2.3 SV 36
– Class 1 Sound Calibrator
Sound calibrator is a device which produces sound pressure of
defined level and frequency.
SV 36
Sound calibrator produces sound pressure of declared levels
- 94 or 114 dB at a frequency of 1 kHz.
This calibrator is equipped with autorun function. It starts generation
of the declared sound pressure automatically after insertion of the
microphone into the calibrator hole.
2.2.4 SB 272
– External rechargeable battery
SB 272
is an external source of DC power for the monitoring
station. It includes a Lead-Acid rechargeable battery (33 Ah, 12 V)
and is dedicated for outdoor use because of its waterproof case.
The battery capacity enables up to three times longer operating
time of the monitoring station.
The SB 272 set includes the SB 273 indoor charger and a cable for
connection between SB 272 and the monitoring station.
SB 272 has the same connector for charging and for power supply and therefore cannot be used as a power
supply for the monitoring station and at the same time be charged (as the internal station battery when it is
charged from the solar panel or external power supply).
Note: SB 272 cannot be charged by the monitoring station SB 270
power supply!
