Introduction
1.1 General Description
The +GF+SIGNET 9050CR Conductivity/
Resistivity Controller is specifically designed to
monitor and control conductivity levels of aqueous
solutions. The controller's compact 1/4 DIN
enclosure (front) is NEMA 4X/IP65 rated and
ideal for installations into instrumentation panels
with limited space.
Optional "plug-in" output cards allow you to
customize your controller to satisfy your application
demands. The controller's unique "slide-out"
chassis design makes option installation fast and
simple. Smart self-configuring microprocessor
based circuitry automatically inventories installed
options during power-up, allowing you to upgrade
your system in seconds without the need for
additional equipment.
The unit's front panel features a highly visible
4.5 and 8-digit liquid crystal display with
adjustable contrast. Measured conductivity/
resistivity and relay status is accessed at a glance.
Channel selection and solution temperature is
accessed with a touch of a button. During
calibration the user is prompted with clear
step-by-step instructions on the front panel display.
The 9050CR is designed for use with
+GF+SIGNET 3-28XX-1 series sensors, covering
a wide range of conductivity/resistivity
measurement. Each sensor is equipped with a
PT1000 temperature compensation device for
accurate temperature sensing (sec. 2.1).

Sensor Selection
and Installation
2.1 Sensor Selection
The 9050CR controller is compatable with +GF+
SIGNET 3-28XX-1 series sensors. +GF+Signet
offers five sensor versions satisfying a wide range
of measurement, listed below.
For optimum sensor performance and life, the
following requirements MUST be met:
• Verify your system's conductivity/resistivity
range.
• Verify the maximum pressure/temperature
specification for the sensor under consideration
is within your process range.
• Verify wetted sensor parts are chemically
compatible with process fluids (e.g. Compass
Corrosion Guide or equivalent).
Choose the +GF+Signet sensor best suited for
your application from the following:
