APT 3500 Smart Pressure Transmitter

APT3500-D-1

The APT 3500 Smart Pressure Transmitter is a microprocessor-based high-performance transmitter, which has flexible pressure calibration and output, automatic compensation of ambient temperature and process variable, a 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 an application method. All data of the sensor is to be input, modified and stored in EEPROM.
