For ventilation and air-conditioning
The model A2G-540 is used to control differential pressure and volume flow of air and also non-aggressive and non-flammable gases in ventilation and air-conditioning technology. The A2G-540 can be used as a P-, PI-, PD- and PID controller.
By selecting the respective component manufacturer in the menu, the correct air flow calculation formula is automatically taken into account. To further optimise the air flow measurement under extreme ambient conditions such as altitude and high medium temperature, suitable sensors can be directly integrated.
The piezoresistive measuring element is temperature-compensated and particularly stable over the long term. It records even the smallest pressure differences and thus ensures high reliability and the highest measurement accuracy. The measured values are available as analogue voltage
and current signals, digitally via the RS-485 interface using Modbus® RTU or via LoRaWAN® (LPWAN). Integration into any control system or directly into cloud solutions is therefore easily possible.
The A2G-540 has freely adjustable measuring ranges. The instrument can be set using the WIKA app and NFC and, depending on the version, using buttons and a display. Efficient project documentation is possible using instrument parameter file readout via NFC and smartphone. The indication of up to four measured values and two relay states can be read from all viewing angles thanks to 2" TFT colour display with traffic light function and individualised measurement parameter lettering.
The construction of the A2G-540 is robust and weather-proof (IP65). The case can be opened without tools thanks to the snap-on cover.
