The Watteco VENTIL’O device is a battery-powered IoT sensor that allows the monitoring of a Continuous Mandatory Ventilation (CMV) system or Air Handling Unit (AHU) by periodically taking vacuum pressure measurements. The following data is periodically transmitted over the LoRaWAN® network:
• Average of vacuum pressures measured,
• Minimum and maximum vacuum pressure measured,
• Low battery voltage
• Trigger input (if option used)
In the event of a threshold being exceeded, an alarm is transmitted. Powered by a battery, the autonomy of the sensor is greater than 10 years for a configuration with a vacuum pressure measurement every 15 minutes and a transmission every 6 hours.
The Sensor is Equipped with:
- LoRaWAN®, Class A
- Easy to install and use
- Differential data compression
- Autonomy > 10 years
- Depression measurement
• Measuring range: 0 / + 500Pa
• Accuracy: -/+10Pa from 0 to 200Pa; -/+5.5%
beyond this range
• Resolution: 1 Pa - Room temperature measurement
• Measuring range: -20°C to +60°C
• Accuracy: -/+2°C between -10°C and +60°C
• Resolution: 0.1°C - IP65 tropicalised
- Optional digital input to monitor equipment status
The sensor should be installed away from direct sunlight, rain and temperature variations so as not to affect these measurements. Installation and commissioning are quick and easy. The sensor is equipped with:
• 2 tubes of 200cm and 2 pipettes for connection to the housing or duct,
• a magnetic switch to activate or deactivate the sensor,
• an NFC identification tag (product code, serial number, batch number).
VENTIL’O+ can be connected to an external equipment using an additional input. With this option, a trigger forces an additional measurement. Typically, it monitors a mechanical vacuum pressure switch
