Pointek Cls200/300 Standard - Siemens Pointek CLS200 Operating Instructions Manual

Pointek CLS200/300 Standard

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.
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.
