Heating, ventilation, and air conditioning make indoor spaces healthier and more comfortable for their occupants – but also account for almost 40% of a building’s total energy expenditure. There are several ways to reduce the energy consumption of offices, schools, stores, laboratories, warehouses, and more. One important step is to incorporate smart differential pressure sensors into HVAC systems.
The A2G-500 series from WIKA helps save energy by continuously and accurately measuring the pressure on both sides of an air filter, which keeps the circulating air free of particulates and allergens. A small difference in pressure indicates that the filter is clean, while a large difference means the filter is dirty. Since an HVAC system has to work harder to push air through a clogged filter, replacing the filter as needed can reduce a building’s energy consumption by up to 25%. This is condition-based maintenance using demand-based control.
The A2G-500 family of differential pressure sensors, air flow sensors, and air flow controllers offers many benefits:
- Future-proof – IIoT-ready with analog and digital signal transmission (Modbus®) and wireless (LoRaWAN®)
- User-friendly – display of all measured values on a smartphone via near-field communication (NFC) or the WIKA app
- Flexible – can be a standalone unit or integrated into a facility’s management system, including in the cloud
- Easy to mount – modular design allows affixing to a wall or DIN rail mounting in a control cabinet
- Easy to integrate – decentralized data node for ≤4 input signals, which reduces cabling costs
- Easy to retrofit – with battery power and wireless connection – no cabling needed
- Durable – with a robust, weather-resistant case (IP65) that snaps on easily
