Image ICA

The ICA family offers high stability and fast response strain gauge or load cell amplifier, converting a strain gauge input into a volt or mA output.

It’s sub-miniature design enables it to be fitted into the majority of transducers for a wide range of signal conditioning for strain gauges, load cells, pressure and torque transducers.

Available in 6 versions, 5 with high performance and ICA5S with industrial stability.

The ICAH range offer very low drift over wide operating temperatures. Optional (ILE) in line enclosure to convert a standard load cell to a conditioned load cell output.

Notes

Note 1 - With 350 Ohm load cell connected.
Note 2 - Factory setting is the typical value shown. For other values fit an alternative calibration resistor.
Note 3 - ICA6 maximum voltage can be increased to 24V with a 1000 Ohm load cell.
Note 4 - The ICA4 can tolerate a lower supply voltage if the output load is reduced e.g. operation is possible at 8V provided that the load does not exceed 150 Ohm.
Note 5 - ICA5 with 1000 Ohms load cell connected.
Note 6 - ICA5 recommended bridge impedance is 1000 Ohms or greater.
Note 7 - 24V minimum supply / sink mode
General Notes The voltage between either of the power supply connections and the load cell shield should not exceed 50V. Any leakage will be greater than 10M Ohms.
