5000TC Series
Toroidal (Electrodeless)
Conductivity Sensors
Overview
The Honeywell 5000TC toroidal
(electrodeless) conductivity sensor
measures the conductivity of solutions from
0.2 to 2000 millisiemens/cm. The sensors
can be used for monitoring chemical
concentration and salinity as well. The
corrosion and fouling-resistant cells are
available with a variety of mounting
assemblies to ensure compatibility for
applications in the chemical, food & dairy,
refinery, pulp & paper, metal finishing and
wastewater industries.

Description
The Honeywell 5000TC sensors are
specifically designed for the monitoring of
conductivity, chemical concentration, or
salinity in difficult applications where
coating, fouling, corrosion, or high
temperatures/ pressures are a concern.
The sensor’s 1 ½” diameter bore minimizes
rough surfaces to ensure that flow
impedance is minimized. A 1000Ω Pt RTD
provides accurate temperature
measurement to ensure proper temperature
compensation. Two types of basic sensor
forms are available with the Honeywell
5000TC – the convertible or sanitary style.
Convertible Style
The 5000TC convertible style toroidal
sensor includes both a ¾” and a ½”
fitting to allow direct fastening to the end
of a pipe for either immersion mounting
or a union-mount adapter for a standard
2” pipe tee. The convertible style can
also be insertion mounted into a 2” ball
valve assembly. Convertible sensors
are available in PEEK, PVDF, PFA
Teflon, and Polypropylene materials.
Sanitary Style
The 5000TC sanitary style toroidal sensor
includes a clean-in-place style fitting and is
constructed of 3A-approved materials. It has
an integral 2” sanitary-mount flange which
mates to Honeywell sanitary tee mounting
hardware. The sanitary-style sensor includes
a special cap and EPDM compound gasket.
The gasket is also available separately for
mounting to a 2” sanitary clamp-type ferrule or
butt-weld tee. Sanitary sensors are available in
PVDF, PFA Teflon, and Polypropylene
materials.

Wetted Materials
To simplify chemical resistance problems, these sensors are constructed so that only
one material is wetted by the process. The wetted material is non-conductive to
insure that the sensor is electrically isolated from the process fluid. The 5000TC
sensors are available in four different material types – PEEK, PFA Teflon,
Polypropylene and PVDF.
PEEK
(Polyetheretherketone)
This material type is ideal for the broadest range of applications within the chemical, pulp &
paper, and refinery industries. The only known materials to severely attack PEEK are very high
concentrations of acids, such as nitric or sulfuric. It has a higher temperature capability than the
Polypropylene or PVDF sensors.
This material type is ideal for extremely corrosive applications, especially high concentrations of
sodium hydroxide, nitric acid, sulfuric acid, or hydrofluoric acid. It has the highest temperature
rating of the four sensor types. It is also ideal for applications which have a tendency to coat the
sensor.
This material type is ideal for wastewater applications where the temperatures and pressures are
close to ambient and chemical compatibility is not a serious concern.
This material type is one of the most rigid and abrasion-resistant materials. It has good chemical
resistance to halogens, such as chlorine or bromine. It is ideal for applications which require
higher pressure ratings, but do not have high temperatures, such as water treatment applications
in the semiconductor industry.

*Ratings for the above Honeywell sensor and mounting hardware combinations are based upon water service. More severe service
may require a correction factor. Includes immersion mount, union adapter mount, and sanitary mount. Separate specifications are
provided for the insertion/removal device.
**Sanitary mounting hardware ratings are for 51451248-001 hardware using the 51451257-001 heavy duty sanitary clamp. Other
hardware and clamp combinations may reduce the listed ratings.
