Miniature Strain Gauge Signal Conditioner, Converts Load Cell to 4-20mA & 0-10V (ICA S & H)

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

The ICA family offers high stability and fast response.

The Miniature Strain Gauge Signal Conditioner is available in 6 versions with two performance categories S & H (industrial & very high stability).

The ICAH range offer very low drift over wide operating temperatures.

ATEX certification pending on some variants.

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.
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.
