Pointek Cls200/300 - Siemens Pointek CLS200 Operating Instructions Manual

Pointek CLS200/300

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 Standard, please see
manual 7ML19985JH02.
• 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 Digital 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 plastic
for effective capacitance measurement.
The power supply is galvanically isolated and can accept voltages in the range 12 to 30 V DC
(12 to 24 V DC for Intrinsically Safe (IS) models), 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. Pointek CLS200/300 Digital can be used either:
• as a standalone unit, programmed locally using the local user interface, or
• installed as part of a network, programmed remotely using SIMATIC PDM on a Profibus PA
network (or locally using the Local User Interface).
