Differential pressure sensor A2G-500

vacuumpiezoresistive4-20 mA

Measurement of differential pressure, gauge pressure and vacuum Monitoring of filters, ventilators and heat exchangers Pressure monitoring in ventilation ducts, laboratories, production areas and clean rooms Special features 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 No cabling effort for retrofit projects thanks to battery operation and LoRaWAN® Decentralised data node − up to four input signals − reduces cabling effort and installation costs Reduction of installation costs due to simple wall or DIN rail mounting in a control cabinet Description The model A2G-500 is used to measure differential pressure, gauge pressure and vacuum in air and also in non-aggressive and non-flammable gases in ventilation and air-conditioning systems. 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®. Integration into any control system or directly into cloud solutions is therefore easily possible. With relay outputs, the instrument becomes a cost-saving differential pressure switch or 2-point controller. The A2G-500 has freely adjustable measuring ranges. The instrument can be set using the WIKA app and NFC and, depending on the version,
