Industrial 20842200 PWA Auto Calibration Board

The Air Monitor Corporation 20842200 Rev. 01 PWA Auto Calibration Board is an OEM replacement PCB for the Veltron II pressure and flow transmitter system. It provides automatic zeroing and calibration control via a microprocessor-controlled calibration interface, helping compensate for thermal, electronic, and mechanical drift to maintain long-term measurement accuracy. Designed to support differential pressure and airflow measurement systems within the Veltron II, this board enables self-calibration capabilities for critical airflow monitoring. Common applications include commercial HVAC systems, cleanrooms, laboratories, pharmaceutical manufacturing facilities, industrial ventilation systems, and building automation.
