ICA In-Cell Analogue Strain Gauge Amplifier

Features :

  • Standardised mounting hole for faster & easier installation
  • Standardised excitation 5V DC
  • Full CE approval
  • Plated through holes for wire connections
  • Maximum height 7.6mm
  • Cost effective with attractive discounts on quantity orders
  • Robust design, reverse polarity & short circuit protected
  • Fast calibration procedure
  • Can be integrated into the majority of LCM Systems sensor products

The second generation ICA (in cell amplifier) is an extremely high performance strain gauge amplifier, converting a strain gauge input to a volt or mA output.

Its sub-miniature design enables it to be fitted into the majority of load cells, pressure and torque transducers.

The amplifier is available in six versions, offering a range of current and voltage outputs. All amplifiers have a wide operating voltage range.

LCM Systems can integrate any of the ICA range of products into the majority of our sensor range. For applications where this is not possible, we can supply a small inline enclosure (ILE), which incorporates the ICA.
