The APT 3200 Smart Pressure Transmitter is a microprocessor-based “smart” pressure transmitter. It uses a piezoelectric pickup optimized & accurately characterized to compensate for ambient temperature effects with a patented temperature compensation algorithm that ensures for high precision & long-term stability in gauge and absolute pressure measurements over a wide range of operating conditions. APT 3200 is a two-wire loop power transmitter and has a standard 4/20mA output scaled for desired output pressure range.
