Performance - Siemens Pointek CLS 200 Instruction Manual

The sensor can be set to detect either the change in capacitance as the product level
approaches the antenna tip, or the change when the probe becomes covered.
Detection Range
The functional detection range depends on the dielectric constant of the material
monitored. The detection range will be shorter when the material has a lower dielectric
constant, and longer when it has a higher dielectric constant.
Specifications: analog model

PROFIBUS PA electronics: mode of operation
The process variable to be measured is generally referred to as the input variable.
The input variable provided by the sensor is an isolated digital frequency signal. This is
evaluated in a microprocessor and made available via PROFIBUS PA. The data for
transmitter parameterization is stored in non-volatile memory.
