Description
The CTA Signal Conditioner provides the
excitation current (instrument power) that
the CTL Hall-effect sensor requires, as
well as amplifying the low-level (mV) signal
into a more typical signal. The CTA is calibrated
to the output of the specifi c CTL selected
for the application. Each CTA model has
a specifi c input range (mV) which corresponds
to the output of the CTL.
The
CTA family has two different types; Direct
and RMS. Direct models provide an isolated
output that is directly proportional to
the amplitude and frequency of the input
signal. If the input signal is ac, then
the output signal is ac. If the input signal
is dc, then the output signal is dc.
The
RMS output models provide an output which
is directly proportional to the RMS of the
input signal. The output is dc regardless
of whether the input is ac or dc. Each type
has four output options: 1mAdc, 4-20mAc,
10Vdc, or 5Vdc. DC instrument power options
are available from 12 to 48Vdc.
