About Pointek CLS 300
Note:
Pointek CLS 300 is to be used only in the manner outlined in this
instruction manual.
The Pointek CLS 300 capacitance level switch provides output on high or
low process material levels. When the measured material is at the desired
level, the change in capacitance is sensed and a level alarm is triggered.
This could be either a “high level alarm” (material rising to reach the desired
level) or a “low level alarm” (material falling to reach desired level).
Pointek CLS 300 Outputs
One form `C' (SPDT) relay
One isolated, non-polarized, solid-state switch

Installation
Location
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 Pointek CLS 300 as supplied in the standard probe lengths is normally
mounted on the vessel top (high detection alarm) or through the tank wall at
the detection level (high or low detection alarm).
The cable version is designed for top mounting. The cable suspends
vertically so that it reaches into the process at the desired detection level
(high or low detection alarm).
