DOTX-45 - 4 -
Part 1 - Introduction
1.1 General
The Model DOTX-45 is a highly versatile on-line monitoring system designed for
the continuous measurement of dissolved oxygen in solution. The full scale
operating range of the system 0-40 ppm, and the sensing system will operate on
water streams with temperatures ranging from 0 to 50°C.
The basic sensing element used in the dissolved oxygen monitor is a galvanic
membrane sensor which measures oxygen directly.
Monitors are available in two electronic versions, a loop-powered 2-wire
transmitter or an AC powered monitor with integral alarm relays and dual 4-20
mA output capability.
1.2 Standard System
The standard model DOTX-45 system includes two components, the dissolved
oxygen analyzer and a dissolved oxygen sensor. For connection of the sensor to
the electronics, a 25' cable is supplied. Up to an additional 1000 feet of
interconnect cable may be added using a junction box. All required spare parts
are also provided with the basic system, including spare membranes, electrolyte,
and o-rings.
1.3 Features
• Standard electronic transmitters are designed to be a fully isolated, loop powered
instruments for 2-wire DC applications. Optional integral power supply card for
115 VAC operation is available.
• High accuracy, high sensitivity system, measures from 0.1 ppm to 40.0 ppm
through 2 internal automatic ranges.
• Output Hold, Output Simulate, Output Alarm, and Output Delay Functions. All
forced changes in output condition include bumpless transfer to provide gradual
return to on-line signal levels and to avoid system control shocks on both analog
outputs.
