EC-501A & EC-501A(G) Control Unit


The Dynatrol® EC-501A and EC-501A(G) Control Unit combines with the DJ and G Series Dynatrol® Level Detectors, including Sealed and Suspended units. Within the Control Units, a SPDT relay is operated from the On/Off signal of the Dynatrol® Level Detector. Simply actuate process control equipment, level alarms or indicator lights from the contacts of this control unit.





EC-501A & EC-501A(G) Control Unit


The Dynatrol® Level Detector System also contains the electronic circuitry that both operates the level probe and makes decisions regarding level switching. The control unit is the EC-501A.


The EC-501A level switch control unit performs frequency and voltage analysis to make decisions regarding the actual level switch point. This technology has been added to the level control in order to reduce false tripping and make level measurements more dependable. This combination of level sensor design and our unique electronics, makes our level switch system both reliable and rugged.
