Overview
The Automation Products CL-10 DJT is a vibrating level detector (Dynatrol brand) engineered for reliable, maintenance-free level detection in bulk solids handling systems. The CL-10DJT is the high-temperature variant, designed for applications requiring operation up to 500°F. Paired with the EC-501A control enclosure, this detector provides a complete sensing and control solution for point-level indication with no field adjustments required. The 1000 PSIG pressure rating and CSA explosion-proof certification make it suitable for demanding industrial environments.
Key Features
