Introduction
1
Pointek CLS100 is a compact 2-wire capacitance switch for level detection in constricted
spaces, interfaces, solids, liquids, slurries, and foam. The stainless steel process connection
versions (7ML5501) have an effective process temperature range of -30 to +100 °C (-22 to
+212 °F) and the synthetic process connection version (7ML5610) has an effective process
temperature range of -10 to +100 °C (+14 to +212 °F).
Note
•
Use Pointek CLS100 only in the manner outlined in this instruction manual.
•
For applications in areas classified as Hazardous, observe any restrictions according to the
relevant certificate.
Pointek CLS100 versions:
•Integral cable version with stainless steel process connection and probe options of PPS or
PVDF.
•Enclosure version (thermoplastic polyester enclosure) with stainless steel process
connection in combination with a PPS or PVDF probe.
•Enclosure version (thermoplastic polyester enclosure) with fully synthetic process
connection combined with a PPS probe.
Features
•NPT, R (BSPT), G (BSPP) process connections.
•Corrosion resistant construction, PPS, and 316L stainless steel (optional PVDF wetted
parts).
•Non-polarized, solid-state switch or relay output (enclosure version with fully synthetic
process connection only)
Applications
•Liquids, slurries, powders, granules, and solids
•Foods and pharmaceuticals
•Chemical and petrochemical
•Hazardous areas

2.1 Location
Note
•
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.
•
When using multiple units, sensors must be 100 mm apart. Mount diagonally if vertical
space is restricted.
Pointek CLS100 is normally mounted into the vessel top (high detection alarm) or through
the tank wall at the detection level (high or low detection alarm).

3.1 Safety notes
Intrinsically safe supply
For intrinsically safe models, power must be supplied from an Intrinsically Safe power source,
otherwise protection is no longer guaranteed.
Process pressure
The device construction allows process over-pressure up to 10 bar (146 psi). This pressure is
allowed for test purposes. The definition of the Ex approvals are only valid for a container-
over-pressure between -0.2...+0.1 bar (-2.9 ...+1.45 psi). For higher or lower pressures, the
approvals are not valid.
Chemical resistance against the medium
If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely
affected, thus ensuring the type of protection is not compromised. Aggressive substances,
e.g. acidic liquids or gases that may attack metals, or solvents that may affect polymeric
materials.

The mA current loop can be wired in either polarity to determine high or low level operation
as shown in the examples beginning on
Non-intrinsically-safe version (Page 11). The cable
shield should be connected to terminal 3 on the terminal block along with the provided
ground wire.

3.5 Definitions
The alarm conditions below can be detected in a fail-safe or non fail-safe mode.
Fail Safe
•The sensor connection arrangement is fail-safe if the output status is in high alarm status
when power fails; open contact state prevents material overflow.
•The sensor connection arrangement switches to the fail-safe low alarm status when
power fails; this open contact state prevents material running dry.
High Alarm
When material reaches a maximum process level, covering the probe.
Low Alarm
When material reaches a minimum process level, uncovering the probe.
