High measuring accuracy, modular design and IIoT capability - the three new instruments in WIKA's A2G family are designed to be perfect for integration into both new and existing ventilation and air conditioning systems.
The WIKA Group from Klingenberg is one of the world's leading suppliers of pressure and temperature measurement technology. The company from Lower Franconia has now added three new measuring instruments to its A2G family, thereby expanding its smart sensor portfolio for ventilation and air conditioning systems in public and commercial buildings. According to WIKA, the new instruments A2G-500, A2G-520 and A2G-540 impress with their high measuring accuracy, modular design and robust construction. They should be easy to integrate into new and existing ventilation and air conditioning systems.
The A2G-500 measures differential pressure, relative pressure and vacuum with a measuring accuracy of plus/minus 0.5 percent. The A2G-520 is preferably used on components such as fans, where it measures the pressure difference and precisely calculates the volume flow using a calibration factor. Finally, the A2G-540 is used to control differential pressure and volume flow. Overall, the A2G family offers a future-proof solution, as the new devices support all common signal transmission paths. They can be integrated into control and regulation systems or an IIoT cloud environment via an analog or digital signal as well as wirelessly (LoRaWAN).
The modular design also allows users to expand the functionality with additional options such as a display, relay or additional inputs and outputs as required. According to their developers, commissioning and operation with the WIKA app is simple and user-friendly. The weatherproof devices are robust and even maintenance-free with automatic zero-point adjustment. The display's traffic light function shows critical system statuses at a glance.
