The ICA range has
six models to give a wide choice of outputs:
ICA1 is a 3-wire
device with 0-10V output
ICA2 is three-wire 0-5V
ICA3 is 4-wire ±10V
ICA4 is 3-wire 4-20mA
ICA5 is 2-wire 4-20mA, and
ICA6 is 3-wire ±10V.
All of the models are available as "industrial stability" (S)
versions, and (except for ICA5) as "very high
stability" (H) versions. Additionally, the ICA5
is available as an ATEX approved version.
The ICA series are
state-of-the-art, precision amplifiers constructed using
surface-mount technology and mounted in a cylindrical
package only 19.5mm in diameter and 7.6mm high. They have
solder pads for external connections, potentiometers for
adjusting offset and gain, a high noise immunity and permit
precalibration of the electronics to the transducer to save
time at final installation, and allow screw mounting and
earth bonding for EMC.
Once calibrated and fitted, the ICAs
will operate maintenance-free, and the use of such a
precision amplifier close to the strain gauge minimises
noise pickup and allows use in installations requiring long
cabling lengths without loss in performance.
The analogue outputs allow direct
connection to a range of analogue output devices, such as
chart recorders, displays, industrial instrumentation or,
with an A/D card, PC and PLCs.
Said Aptifirst's Roy Carter, "The
ICA series is a beautifully engineered range of
precison analogue amplifiers which are very cost-effective
devices for converting the fragile and delicate signals from
a raw strain gauge bridge to robust high-level signals.
Their light weight - only a few grammes - makes them ideal
for dynamic applications where weight is crucial. They have
uses in many fields - for engineering projects, laboratory
apparatus, process instrumentation and, of course, for load
cells, pressure sensors, torque transducers and similar
Other strain gauge conditioning
instruments available from Aptifirst include the D-Cell,
DSC and DSCUSB intelligent strain gauge
amplifiers (all of which will permit a strain gauge device
to be connected directly to a computer system), the T24
Radio Telemetry system, which has a Strain Gauge
input module, the SGA analogue strain gauge
amplifier, the ADP15 series of panel- and DIN-rail
mount process control instruments and the ADW15 and
SMW controllers for weighing processes.
Aptifirst also has a range of
cost-effective panel-mounting temperature controllers,
timers, dataloggers and sapphire window optical process
