Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific

Note
•
Pointek CLS200/300 is available in two models: the standard model, and the digital model
with integral local display. For information on the CLS200/300 Digital, please see manual
7ML19985JJ02.
•
Pointek CLS200/300 is to be used only in the manner outlined in this instruction manual,
otherwise protection provided by the equipment may be impaired.
•
This product is intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency based communications.
Pointek CLS200/300 is a versatile capacitance switch, ideal for level detection of interfaces,
solids, liquids, slurries, and foam, and for simple pump control. The switch responds to the
presence of any material with a relative dielectric constant of 1.5 or more by detecting a
change in capacitance, which is registered as a change in oscillating frequency.
The switch can be set to detect before contact or on contact with the probe. The design of
the CLS200 Standard allows the instrument to operate independently of the tank wall or pipe,
so it does not require an external reference electrode for level detection in a nonconductive
vessel such as concrete or plastic1). The CLS300 Standard requires a connection to
earth/ground for effective capacitance measurement.

4.1 Pointek CLS200/300 applications
Pointek CLS200/CLS300 standard
Operating Instructions, 05/2021, A5E47827796-AA 11
The power supply is galvanically isolated and can accept voltages in the range 12 to 250 V
AC/DC, depending on the application. The materials used in the probe construction provide a
high level of chemical resistance, and an excellent temperature rating on the process wetted
portion of the probe: up to 125 °C (257 °F) for the CLS200 and 400 °C (752 °F) for the
CLS300.
Modular design and construction provide a wide choice of configurations, including rod,
cable, and sanitary versions. When used with a SensGuard protection cover, the CLS200
sensor is protected from shearing, impact, and abrasion, in tough primary processes.
1) Refer to Technical data (Page 50) for CE applications.
4.1 Pointek CLS200/300 applications
Pointek CLS200/300 is designed for level detection and simple pump control in a variety of
applications:
•Liquids, solids (powder and granules), slurries, interface detection (for example, oil/
water), and foam detection
•Foods and pharmaceuticals
•Chemical and petrochemical
•High pressure and temperature

5.1 Safety notes
Process pressure
The device construction allows process over-pressure up to 10 or 25 bar (146 or 365 psi). This
pressure is allowed for test purposes. The definition of the Ex approvals are only valid for a
container-over-pressure between -0.2 to +0.1 bar (-2.9 to +1.45 psi). For higher or lower
pressures, approvals are not valid.
Process and ambient temperature
Please check the ambiment and process temperatures at Flame Proof and Dust Ignition Proof
(CLS200) (Page 71) for the specific configuration you are about to use or install.
Chemical resistance against the medium
If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection is not compromised. Aggressive
substances: e.g. acidic liquids or gases that may attack metals, or solvents that may affect
polymeric materials. Suitable precautions: e.g. establishing from the material's data sheet
that it is resistant to specific chemicals.
Cable entry devices / blanking elements
•Dust Ignition proof. For use in potentially explosive dust atmospheres: The cable entry
devices and the blanking elements of unused apertures shall be of a certified type,
suitable for the conditions of use and correctly installed. The minimum ingress protection
requirement of IP6X according to EN 60529 must be satisfied.
•Flameproof. For use with potentially explosive gas atmospheres: the cable entry devices
and the blanking elements of unused apertures shall be of a certified flameproof type,
suitable for the conditions of use and correctly installed.
•Versions with cable gland mounted by default. The used cable gland is only suitable for
fixed installations. The installer is responsible for providing appropriate strain-relief to
prevent pulling or twisting.
•Versions with blanking element mounted by default. Blanking elements are not to be
used with any form of adaptors or reducers.
