SECTION 1 - INTRODUCTION

The Type TB404 Toroidal Conductivity Sensor Series monitors a wide vari-
ety of process liquids. The robust, encapsulated design of the sensor protects
the internal electronics from corrosive process solutions.
This instruction contains information on sensor installation only. For infor-
mation on maintenance, testing, troubleshooting, calibration and repair, refer
to the product instruction of the analyzer or transmitter used with the sensor.
This instruction is intended for use by technical personnel responsible for the
installation of the Type TB404 sensor.
The Type TB404 sensor employs an encapsulated design that makes it ideal
for aggressive and harsh process streams. The analyzers and transmitters for
which the sensor was designed measure moderate to high conductivity
streams.
The sensor is available with a submersible adapter that accommodates sub-
mersible installations such as tanks and open vessels or waterways. The
in-line flow assembly provides installation capability for pipelines and tanks.
There are also two types of hot tap assemblies available: Low pressure units
with either hand or wrench-tight compression fittings and high pressure
units. The high pressure units can be ordered with ball valves. Ball valves for
low pressure units must be ordered separately. Finally, there is a two-inch
sanitary sensor that provides installation capability for sanitary pipelines and
tanks with two-inch tri-clamp fittings.
The Type TB404 sensor is intended to provide measurements for process
monitoring and/or control applications.
Some typical applications include the measurement for display and control
of the conductivity of process fluid streams, boilers, pulping and sugar
liquor, concentrated chemical streams, clean-in-place systems, food and
pharmaceutical systems, brine, and solutions with heavy solids or high ionic
strength liquids.
This instruction consists of four sections and a set of procedures. After
becoming completely familiar with it and the sensor, it can be used as a ref-
erence.
