ACI Instrumentation

ACI’s sensors are built to measure and monitor essential environmental parameters such as temperature, humidity, pressure, and gas concentration; key factors in maintaining efficient and safe system operation. Each product is designed with a focus on three critical performance areas: accuracy, ensuring stable output over time; tight tolerances, providing consistent operation under varying manufacturing and installation conditions; and calibration stability, maintaining measurement precision for the life of the sensor.

Manufactured and tested in the USA, ACI instrumentation utilizes five main sensing technologies: thermistors and RTDs for temperature, resistance-based technologies for humidity, piezoelectric diaphragms for differential pressure, and electrochemical sensors for gas detection. These proven technologies ensure reliable and repeatable performance in diverse applications, from HVAC monitoring and process automation to cleanroom and environmental control. Every ACI sensor is designed to integrate seamlessly into modern automation systems, with support for analog, resistance, and digital signal formats to ensure compatibility with BMS, DDC, and industrial control platforms. The result is a sensor lineup that delivers dependable accuracy, ease of installation, and robust construction for long-term use in demanding conditions.
