APT 3100 Overview

The APT-3100 Smart Differential Pressure Transmitter is a high-performance, micro-processor based transmitter that can meet even the most stringent of your measurement needs. The APT-3100 has the ability to measure differential, absolute, and gauge pressures as well as calculate flow while providing numerous output options, including 4-20 mA, 1-5 V, HART, and pulse totalization.

With the built-in push buttons, configuration has never been easier. While you can still configure the APT-3100 via a HART communicator, you no longer need one because you can perform all of the same functions locally without the need to even remove one of the device end caps. You now can be finished with your configuration in less time than it used to take you to connect your HART handheld!
