The Manual - Siemens Pointek CLS 200 Instruction Manual

Pointek CLS 200 analog model
Notes:
• Pointek CLS 200 is to be used only in the manner outlined in this instruction manual,
otherwise protection provided by the equipment may be impaired.
• Pointek CLS 200 is available in two models: the analog model, and the digital model
with integral local display. Part I of the manual only discusses the analog model.
Please see Part II, page 27 onwards, for information on the digital model
Pointek CLS 200 is a versatile capacitance switch with a high level of chemical resistance;
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 dielectric constant of 1.5 or
more by detecting a change in capacitance, which is registered as a change in oscillating
frequency. It can be set to detect before contact or on contact with the probe. The design
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 power supply is galvanically isolated and accepts a wide range of voltages
(12- 250 V AC/DC). The stainless steel and PPS
provide a high level of chemical resistance, and a temperature rating up to 125
on the process wetted portion of the probe.
Modular design and construction provide a wide choice of configurations, including rod,
cable, and sanitary versions. When used with a SensGuard protection cover, the sensor
is protected from shearing, impact, and abrasion, in tough primary processes.
