Introduction to the Pointek CLS 300
Note: Pointek CLS 300 is to be used only in the manner outlined in this instruction manual.
The Pointek CLS 300 capacitance level switch provides output on high or low process
material levels. When the measured material is at the desired level, the change in
capacitance is sensed and a level alarm is triggered. This could be either a high level alarm
(material rising to reach the desired level) or a low level alarm (material falling to reach
desired level).

Installation
Location
Notes:
•Installation shall only be performed by qualified personnel and in accordance with local
governing regulations.
•This product is susceptible to electrostatic shock. Follow proper grounding
procedures.
The Pointek CLS 300 as supplied in the standard probe lengths is normally mounted on the
vessel top (high detection alarm) or through the tank wall at the detection level (high or low
detection alarm).
The cable version is designed for top mounting. The cable suspends vertically so that it
reaches into the process at the desired detection level (high or low detection alarm).

High Temperature Version
Ceramic Active Shield Insulator and Thermal Isolator
Provides a ceramic Active Shield insulator and a Thermal Isolator for when the process
temperature is greater than 200EC / 392EF and/or for when the product to be detected is very
abrasive. The high temperature version is rated for applications up to 400EC / 752EF.
The Thermal Isolator provides a separation distance between a high process temperature
inside the vessel and the electronic housing outside the vessel. This reduces the operating
temperature of the electronics to a value equal to or less than 85EC/185EF.
See Temperature and Pressure Recommendations for Application on page 25.
Warning: Do not cover the Thermal Isolator section of this Point Level Switch
device with insulation material.

Rod Version
The rod version of the CLS 300 is available in standard lengths from 350mm (14") up to 1000mm
(40"). Other lengths using stainless steel or other metals can be attached as an electrode
when required. Ensure that the thread end conforms to the exact dimensions as shown
below. Rod lengths beyond 1000mm (40") are not recommended.
Changing Probe Length
The probe length can be shortened in the field by cutting the electrode.
Warning: To prevent damage, do not apply torque directly to the main probe assembly.
Option 1
If the electrode is removable:
1. Remove the electrode by
releasing the set screw and
turning the threaded electrode
end counter-clockwise.
2. Place the upper part of the
electrode in a vice as shown.
3. Use a wrench to loosen the
lower portion of the electrode.

Option 2
If electrode is NOT removable:
1. With unit mounted in place,
place two wrenches as shown.
2. Hold the upper wrench steady
and turn the lower one counter-
clockwise to loosen the lower
portion of the electrode.
The Wrong Way
If the process connection itself is put in the vice, the probe’s internal parts will rotate along
with the wrench and the unit may fail.

Cable Tensile Strength
Do not exceed the tensile strength of the cable at 1900kg/4188lbs.
Always confirm that the load carrying capability of the silo/tank roof is sufficient to withstand
the actual force on the cable conditions, especially where the force will be, or could be, as
great as 1900kg/4188 lbs. A cable (rope) probe with a PFA jacket reduces the amount of
possible product build-up on the probe as well as the tensile force on the cable.
Cable Weights
A standard weight with optional attachable Butterfly enhancer is available for the cable
version. We recommend the Butterfly weight for lower dielectric constant materials (often in
solids) because it increases the change in capacitance when the material comes in contact
with the cable end. This occurs when the silo is quite tall (> 15 m/45 ft) and the dielectric
constant is less than (>r< 4).
Shortening the Cable
Methods
•An angle grinder (preferably with a disc suitable for stainless steel)
or
•Wire cutters (suitable for piano cable Ø6 – 9mm).
Procedure
1. Remove Butterfly (if present) from weight.
2. Loosen the three set screws and pull weight from the cable.
3. Grind/cut the cable to the required length, and then remove rough edges from the
cable.
4. Ensure that cable strands are properly seated in the lay of the cable (i.e. no wire
strands sticking outside the normal cable profile). Make sure ALL strands are
properly seated before continuing the assembly.
5. Push the weight onto the cable while simultaneously rotating it counter-
clockwise around the cable. Make sure that no cable strands are pushed out of
their position in the cable and that the cable is fully inserted.
6. Re-fasten the weight by tightening the three set screws.
7. Re-attach Butterfly (if required) to the weight.
