Miniature Analogue Strain Gauge Amplifier with ± 10 V 4 wire OutputICA3H
Description
ICA3H – Miniature Strain Gauge Amplifier (±10 V Output)
The ICA3H is a high-stability miniature strain gauge amplifier designed for seamless OEM integration into load cells, force sensors, and other strain-based transducers. It delivers a ±10 V analogue output over a 4-wire connection, offering excellent signal range and compatibility with standard measurement systems.
As part of the ICAH series, the ICA3H offers very high stability and minimal temperature drift, making it ideal for precision applications in industrial, automotive, and aerospace sectors. Its miniature format and robust performance make it a proven solution for embedded instrumentation.
The ICA range includes:
-
ICA1H, ICA2H, ICA3H, ICA4H, ICA6H – High-performance OEM amplifier variants
-
ICA5S – Industrial-grade stability for general-purpose use
-
The ICA5 is also available in an intrinsically safe ATEX-certified version (ICA5ATEX) for hazardous area applications.
An optional ILE (In-Line Enclosure) allows external installation to convert standard load cells into conditioned-output sensors.
