Standard IQ remote hand stations are suitable for applications
where vibration and shock severity does not exceed the
following:
Type Level
Plant induced 1g rms total for all vibration within the frequency
vibration range of 10 to 1000 Hz
Shock 5g peak acceleration
2g acceleration over a frequency range of 1 to
Seismic
50 Hz if it is to operate during and after the event
Independent tests have shown that at 1m
Emitted noise
generated noise does not exceed 65 db(A)
