How it Works

The Dynatrol DJ-7 Level Sensor consists of a rod-style probe that is installed through the wall of the storage tank, bin, or silo at the point of desired level detection. When the probe is uncovered, the rod is free to vibrate and produce an output signal that operates a relay, indicating the rod is uncovered and a low level exists. A dampening of the oscillation occurs when the rod is covered and the resultant loss of signal de‐energizes the relay, indicating a high level exists.

The Dynatrol DJ-7 Level Sensor is powered by an EC‐501A Control Unit, which is required for its designed operation. The ON/OFF signal from the Dynatrol level sensor operates a SPDT relay in the EC‐501A Control Unit. The relay’s contacts can be used to actuate alarms, indicator lights or process control equipment.

The EC-501A Control Unit performs frequency and voltage analysis to actuate switching at the desired point level of detection. 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 unique electronics makes our level sensor system both reliable and rugged.

Optional NEMA 4X Assembly

Key Advantages

  • Each Dynatrol® level sensor can be configured for NEMA 4X-rated environments.
  • Epoxy-coated NEMA 4X grade devices can be fit with common clean-in-place (CIP) flange connections.
  • Dynatrol® NEMA 4X assemblies are constructed from corrosion-resistant materials, including custom 450 stainless steel, epoxy coatings and other specialty materials.
  • The Dynatrol® NEMA 4X assembly is available for all Dynatrol® level sensor models, including sealed and suspended configurations.
  • No field adjustment is needed for any of these devices as all level sensor and control unit components have been optimized for a long operating life.
