Miniature Analogue Strain Gauge Amplifier with 0-10 V 3 Wire OutputICA1H
Description
ICA1H – Miniature Strain Gauge Amplifier (0.1–10.1 V Output)
The ICA1H is a high-precision miniature strain gauge amplifier engineered for OEM integration directly into load cells, pressure transducers, and other strain-based sensors. It provides a stable 3-wire voltage output of 0.1–10.1 V, making it ideal for applications that demand high accuracy, wide dynamic range, and signal integrity.
Part of the ICAH range, the ICA1H is designed for very high stability and minimal drift across extended temperature ranges. Its compact format allows for seamless embedding into transducer designs, while advanced filtering ensures excellent EMC performance even in challenging environments.
The ICA range includes:
-
ICA1H, ICA2H, ICA3H, ICA4H, ICA6H – High-performance OEM amplifiers
-
ICA5S – Industrial-grade stability for general-purpose applications
-
ICA5ATEX – Intrinsically safe ATEX-certified version for hazardous area applications
An optional ILE (In-Line Enclosure) allows you to convert a standard sensor into a fully conditioned output device without internal modification.
