ICA Range

The ICA range of miniature strain gauge amplifier offer a high performance strain gauge amplifier in miniature OEM format, designed specifically for fitting inside load cells, converts load cell to 4-20 mA & 0-10 V output.

The ICA family offers high stability and fast response.

The miniature strain gauge amplifier is available in 6 versions, ICA1H, 2H, 3H, 4H & 6H 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 (see manuals in Downloads tab).
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.
