Pressure measuring system ARF8283AB

direct-contactindirectcurrent injection

Overview
The Smart Delta P solution monitors ventilation systems to anticipate maintenance and optimise operation. It integrates an Adeunis Smart Delta P IoT sensor (differential pressure and current measurement), dedicated firmware with mathematical aggregates and edge AI, and the Carl Software IoT platform to process data, build numerical models and generate alerts. The sensor connects to existing ventilation installations via two tubes and a current clamp and learns a normal operating profile before detecting anomalies.

Benefits of the IoT solution

• Enables upstream maintenance qualification
• Reduces intervention and operational costs
• Extends service life of monitored equipment
• Helps ensure indoor air renewal and compliance

Highlights of the IoT solution

• Compatible with any existing ventilation system (AHU, CMV)
• No sensor-side configuration required thanks to on-board AI
• Automatically identifies normal operating modes and derives drifts and alert thresholds

Key components
The solution comprises the Adeunis Smart Delta P IoT sensor with firmware embedding mathematical aggregates, AI and edge computing capabilities for local data processing, and the Carl Software IoT platform for data analysis, numerical model building and alerting/predictive maintenance.

How the IoT solution works
The sensor observes and analyses 'normal' operation during a learning phase. After learning, it detects early signs of abnormal operation and sends alerts to the Carl Software platform via IoT networks. Processed data enables facility managers to adjust ventilation settings and schedule preventive maintenance.
