Pointek CLS300 - Standard
The Pointek CLS300 (standard version) is an inverse frequency shift
capacitance level and material detection switch offering optional
rod or cable configurations with configurable output. Designed for
demanding industrial conditions, it reliably detects liquids,
solids, slurries, foam, and interfaces even under high pressure and
temperature. Its advanced tuning capability effectively compensates
for material buildup on the probe.

Key Benefits
- Active-Shield technology ensures measurement accuracy is unaffected
by material buildup or nozzle interference in the active shield
section
- Solid rod construction provides exceptional performance in
extremely abrasive conditions
- Three LED indicators for adjustment control, output status, and
power monitoring
- High-temperature version capable of operating up to 400 °C (752 °F)
Applications
The Pointek CLS300 standard version features three LED indicators
with basic relay and solid-state switch alarms. Its robust design
makes it particularly suitable for heavy solids applications with
abrasive materials, such as those found in the mining industry. The
fully potted electronics remain unaffected by condensation, dust,
or vibration.
Wetted components are constructed from stainless steel with a PFA
shield for high chemical resistance, while the high-temperature
version uses ceramic and stainless steel. The device accurately
detects materials with both low and high dielectric constants. The
unique Active Shield technology effectively suppresses interference
from material buildup or extended installation nozzles.
The modular design of the Pointek CLS300 offers extensive
configuration options, process connections, extensions, and
approvals to meet specific application requirements for temperature
and pressure. This design simplifies ordering processes and reduces
inventory needs. Available probe configurations include both rod
and cable versions.
Primary Applications:
- Liquids and slurries
- Bulk solids
- High pressure and temperature environments
- Hazardous areas
- Milling and mining applications
