Endura APA592
pH / Redox (ORP) transmitter
Measurement made easy
Introduction
This transmitter is intended for the following uses:
• pH measurement
• ORP or pION measurement
• Ion Concentration measurement
The APA592 transmitter is fully compatible with
ABB’s full range of glass, antimony and redox (ORP)
electrodes. In addition, this transmitter is
compatible with many competitor sensor inputs.
The APA592 has automatic temperature sensor
recognition for both 2 and 3-wire RTD inputs for
common inputs such as Pt100, Pt1000 and
3k Balco.
APA592 transmitters are communication-ready
field devices with microprocessor-controlled
electronics. For bidirectional communication, an
FSK signal is superimposed on the 4 to 20 mA
output signal via the HART protocol.
The graphical user interface (DTM) can be used to
configure, poll and test transmitters on a PC-
specific basis. Handheld terminals such as the
DHH801 also support communication.
The transmitter is equipped with an LCD display
used to show the current process data. The four
keys beneath the display enable the transmitter to
be configured locally.
