APT9500 Series

Datasheet

The APT9500 Series is a high-performance differential pressure transmitter designed for flow measurement applications. Using microcomputer technology, it converts differential pressure into flow values and displays flow rate, totalizer, and differential pressure simultaneously on an LCD screen. Compatible with orifice, Venturi, annubar, and V-cone flowmeters, the APT9500 is highly stable and accurate. It features six-direction rotatable installation, 0.075% accuracy, and two years of stability at 0.2%. With 4-20 mA pulse output, HART communication, and a weatherproof, explosion-proof housing, it ensures reliability in demanding environments. Its keypad allows for direct parameter settings, and zero calibration can be performed with the push of a button.
