Page 5: Introduction
Introduction 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... -
Page 6: Mounting
• 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). - Page 7 Wall Restriction Process Cautions: • Keep out of path of falling material. • Consider material surface configuration when installing unit. • Protect probe from falling material. • Avoid areas where material buildup occurs.

Page 15: Protection Diodes
Always use a protection diode when driving an external relay with the solid state switch or relay contact. This prevents possible switch damage due to inductive spikes generated by the relay coil. Orient the diode based on the current flow. Pointek CLS100 Compact Operating Instructions, 05/2021, A5E32146158-AB... - Page 16 For integral cable equivalents, refer to Enclosure version (Page 9).
