Miniature Analogue Strain Gauge Amplifier with 0-5 V 3 wire OutputICA2H
SKU: ICA2H
Description
ICA2H – Miniature Strain Gauge Amplifier (0–5 V Output)
The ICA2H is a high-performance miniature strain gauge amplifier designed for OEM integration directly into load cells and other strain-based sensors. This compact module converts strain gauge signals into a stable 0–5 V analogue output via a 3-wire connection, making it ideal for modern control systems and instrumentation.
As part of the ICAH range, the ICA2H delivers very high stability and exceptionally low drift over a wide temperature range, ensuring consistent accuracy in demanding environments. Its miniature format, advanced filtering, and robust protection features make it suitable for embedded applications where space is at a premium.
The ICA range includes:
-
ICA1H, ICA2H, ICA3H, ICA4H, ICA6H – High-performance variants
-
ICA5S – Industrial-grade stability for general applications
-
ICA5ATEX – Intrinsically safe ATEX-certified version for hazardous area applications
An optional ILE (In-Line Enclosure) is available to externally mount and protect the amplifier, allowing standard load cells to be easily upgraded to a conditioned-output format.
