Introduction
BPD17 pH / Redox Monitor
Operating Guide - 7 -
Introduction
The BPD17 is a microprocessor controlled pH and Redox (ORP) measurement instrument
that can be used with a wide range of Single ended or differential electrodes to measure
and control a broad spectrum of solution pH or Redox. To achieve this, the instrument
utilises a multifunction LCD to display the primary reading and temperature, show
operational status and to provide an intuitive user interface.
As standard the instrument is a simple to install IP66 rated Wall-mount instrument,
however with the addition of a suitable mounting kit it can either be installed as a Panel-
mount or Pipe-mount instrument.
The instrument has two on-board volt-free normally-open relays with adjustable setpoint
value and hysteresis. Either one can be set to activate if the process variable is above or
below the setpoint allowing the instrument to be used in a variety of dosing or control
applications. Additional setpoint functions include delayed activation, dose alarm timer
and scheduled cleaning, whilst the status of the relays can be seen via the main screen of
the instrument.
Additionally, the instrument features one industry standard, isolated, 0/4-20mA current
output that features adjustable scaling, selectable on-error states and loop fault detection,
allowing the instrument to transmit the primary reading for remote monitoring purposes.
Also fitted are two contact inputs which allow the instrument to be remotely set to an
offline state that forces the relays to deactivate and the current output to a pre-defined
state.
Depending upon version purchased the instrument is powered by either 85-265V AC or 12-
30V DC.
