Relative pressure sensor Delta P

differentialcapacitive0-10 V

Overview
The Adeunis IoT sensor DELTA P (ARF8283AA) is a ready-to-use radio transmitter designed to measure a pressure delta between the inside of a ventilation box and atmospheric pressure or between two sides of an element (e.g. filter). It is intended for remote monitoring of ventilation units, air handling units and building air systems. The device includes 2 digital inputs/outputs (dry contact) and 1 analogue input 0-10 V for connecting an external sensor.

Highlights of the IoT sensor

• Delta pressure measurement: relative to atmospheric pressure or between two zones
• 2 digital inputs/outputs: dry-contact for alarms or status reporting
• 1 analogue input 0-10 V: for external sensor integration
• Local and remote configuration; battery-powered operation
• Available in Smart Delta P version

Functions and actions carried out by the connected sensor

• Measure: delta pressure between atmospheric pressure and the inside of a ventilation box or across an element (e.g. filter).
• Collect: 0-10 V data from a wired sensor (e.g. current clamp to detect power failure).
• Alert: threshold exceedance alerts (pressure delta or via 0-10 V) and alerts on digital input events (e.g. machine fault signal).
• Act: control digital outputs to drive actuators or signal states.
• Operating modes: periodic and/or event-driven; manual measurement trigger (magnet) for maintenance.

Alerts and actuation

• Alerts on threshold exceedance (pressure or 0-10 V)
• Alerts on digital input events (e.g. fault indication)
• Actuation via digital outputs (TOR) to control external devices
