Signal Conditioners
ICP® sensor signal conditioners provide the necessary constant
current excitation voltage to ICP sensors and decouple the
sensor bias voltage from the output. A wide selection of signal
conditioners are available with battery or line power, with or
without gain, in single or multi-channel configurations, and
with manual or computer controlled operation.
BATTERY-PPOWERED SIGNAL CONDITIONER
Battery signal conditioners provide 27 volt, 2 mA constantcurrent power to ICP sensors. Features include the colorcoded circuit check-out meter, a battery test button, and
inputs for both an external battery source and a
rechargeable battery option. Unity gain and selectable
gain units are available.
Power units have either a color-coded circuit check-out meter
or LEDs for monitoring bias voltage on the signal lead. On
the check-out meter, green indicates normal operation, red
indicates a short, and yellow indicates an open circuit.
Single-channel power units are available in sensor kits,
complete with the pressure sensor of your choice, ready to
connect and operate. These kits are provided ready to
connect and operate. See page 74 for detailed information
on sensor kits.

To specify recharge option, add prefix “R” to the model
number (e.g., R480C02 indicates a Model 480C02
Signal Conditioner supplied with model 488A02 battery
charger and three 9-volt NICAD batteries.

LINE-TTYPE ICP® SENSOR SIGNAL
CONDITIONER
AC-type conditioners power ICP low-impedance sensors and
couple them to readout instruments. Output current is adjustable
from 2 to 20 mA. The higher current is an advantage when
driving high-frequency sensor signals over long cables (more
than 100 ft.). Line-power units are factory set at 4 mA, which is
adequate for most applications.

MULTICHANNEL SIGNAL CONDITIONER MODEL 481A02
For powering piezoelectric ICP® sensors, this signal conditioner
provides an effective method for managing large numbers of
sensor channels. Standard features include gain of x1, x10
and x100 with autoranging and RS232 and RS485
computer-control interface. Additionally, LED indicators
monitor normal and faulty operation as well as overload
conditions. Power to the sensors is in the form of a 24
VDC, 4mA (adj. from 2 to 20 mA) constant current
excitation. Sixteen BNC output jacks are also located on
the front panel and 16 BNC input jacks/multipin
input/output connectors on the rear panel.
