The CDTX-90 Series Conductivity/
Resistivity Transmitter is designed for
broad application and ease of setup and
use. The unit can be used for
conductance, resistance, or TDS signal
transmission and display. Mounting can be
accomplished in several options best
tailored to your application requirements.
Full microprocessor based electronics
allow wide operating range, and long term
signal stability due to the elimination or
potentiometers, jumpers and dip switches.

Installation

The transmitter is available in a panel mount or a field version. Select the universal mount kit FP90UM to mount the transmitter on a
surface near the sensor.

1. Panel Mount

FP90UM

CDTX-90-XP

All Panel mount transmitters CDTX-90-XP include a mounting
bracket and gasket for a NEMA 4X (IP65) watertight panel
installation. Panel mount transmitters fit into a standard 1⁄4 DIN panel
cutout.

2. Universal Mount

Kit

CDTX-90-X

The Universal Mount Kit FP90UM can be ordered separately
and includes a conduit base, locking ring, and universal
adapter for mounting the transmitter on a pipe, wall, or other
stationary surface.
