Glorient offers competitive supply of WIKA A2G-520. Competitive pricing, fast quotation.
WIKA A2G-520 - high-precision industrial measurement instrument.
WIKA is a global market leader in pressure and temperature measurement technology. With over 75 years of experience, WIKA instruments are trusted in process industries worldwide. Glorient is a professional supplier of genuine WIKA products with competitive pricing and fast worldwide delivery.
Integrated air flow calculation based on all common formulas IIoT-ready and future-proof thanks to analogue and digital signal transmission (Modbus ® ) as well as wireless (LoRaWAN ® ) Time-saving instrument configuration and display of current measured values on the smartphone via NFC or WIKA app Precise measuring results, even under extreme ambient conditions Reduction of installation costs due to simple wall or DIN rail mounting in a control cabinet
The model A2G-520 measures the pressure difference on components such as ventilators or pitot tubes, e.g. model A2G-FM, and calculates the air flow using the calibration factor (K factor). By selecting the respective component manufacturer in the menu, the correct calculation formula is automatically taken into account. To further optimize 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-520 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-520 is robust and weather-proof (IP65). The case can be opened without tools thanks to the snap-on cover.
