Overview
The APT3500 Smart Pressure Transmitter is a micro processorbased high performance transmitter, which has flexible pressure calibration and output, automatic compensation
of ambient temperature and process variable, configuration of various parameters, communication with HART protocol.
The application is very various, as measuring liquid, gas or steam flow as well as pressure and liquid level by application method. All data of sensor is to be input, modified and stored in EEPROM.
