Pointek CLS200/300
Pointek CLS200/300 Standard
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 non-
conductive vessel such as concrete or plastic. The CLS300 standard requires a
connection to earth/ground for effective capacitance measurement.
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.
Notes:
• 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 7ML19985JJ01.
• 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.

CLS200 Installation
Installation: Pointek CLS200 Standard
Location
Recommended:
• Provide a sun shield to protect the transmitter from direct heat radiation.
Precautions:
• Avoid mounting Pointek CLS200 in locations subject to strong vibrations in the
vicinity, whenever possible.
• Do not exceed the permissible ambient temperature limits (see Environmental on
page 9 for details).
Mounting
Pointek CLS200 (compact threaded probe shown )
For high level alarm (level exceeds normal process level):
• normally mounted into the vessel top, or
• mounted through the tank wall at the detection level
For low level alarm (level drops below normal process level):
• mounted through the tank wall at the detection level
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 housing may only be opened for maintenance, local operation, or electrical
installation.
• Before installing the instrument, verify that the environment complies with any
restrictions specified on the product nameplate.

For high or low level alarm:
• designed for top mounting. The probe suspends vertically so that it reaches into

Mounting Restrictions
Note:
• Keep the sensor at least 50 mm (2") away from any nozzle or tank wall.
• If multiple units are used, allow at least 100 mm (4") between them, to prevent
interference.
