DC Sensors in Bi-directional Applications
What are AC & DC Current Transducers?

Many catastrophes can be avoided by using current sensors to monitor critical loads. When loads are powered by DC dc-sensors-applic-img2current it becomes more of a challenge than monitoring AC current. By far the simplest and most accurate method is to use an NK Technologies' DT or DS series current sensor. This Hall-based non-contact design requires no cutting or terminating of the conductor. Just pass the lead through the sensor, or snap the sensor in place over the lead, and the sensor is ready to go.

DT transducers produce a signal to the control system proportional to the current in the conductor, and the DS switches provide a contact, solid-state or electromechanical relay, which changes state at an adjustable current level.

NK Technologies can provide a cost-effective method to monitor DC powered loads. Compare features with competitive methods; we hope your choice will be the most accurate, reliable and responsive current sensing products available.

New Bi-Directional Sensor Output

Bi-Directional transducers produce a positive voltage signal proportional to the DC current circulating in the primary direction and a negative voltage proportional to the DC current in opposite direction.

Applications include:

  • Monitoring battery charge or discharge current magnitude
  • Indication of DC motor rotational direction
