The Type CL-10DJI, Dynatrol Interface Level Switch has been designed for level detection of interfaces between a liquid and a settled bed of solids.

The DJI Interface Detector operates successfully with consistent results on applications such as carbon/water interface, sand/water interface, catalyst/liquid interface, steeping processes, and other selected applications including interface detection between liquids of significant viscosity differences.

Reliable operation can be achieved with this control in problem applications where the level of solid material is difficult to detect within a specified liquid.  The DJI Interface Level Switch is approved for Class I, Group C & D; Division 1 service.  Specialized units can be used in temperatures exceeding 300°F.

Basic principle of operation:  The level switch is mounted through a 3/4” half-coupling at the point of desired level detection.  The probe, when the solid material is not covering it, is free to vibrate producing an output signal.  This signal operates a relay indicating the probe is uncovered – a low level exists.  When the probe is covered with solid material a dampening of the oscillations occurs and the relay indicates that a high level exists.

The On/Off signal from the Dynatrol DJI Interface Detector operates a SPDT relay in the EC-501A Control Unit.  The contacts of this relay can be used to actuate alarms, indicator lights or process control equipment.

Dynatrol detectors are constructed for long operating life. Requiring no adjustments and having no moving parts, they are virtually wear-free.  Many Dynatrol Level Switches have been in service for 25 and 30 years.

For over 60 years, Automation Products, Inc. has proudly designed and constructed Dynatrol instruments in the U.S.A.
