Current sensors

TF sensors

Flexible current sensors used with DIRIS Digiware, DIRIS A-40 and DIRIS B

TF flexible current sensors measure the load currents of an electrical circuit and send the data to meters and Power Monitoring Devices or current modules via an RJ12 plug-and-play connection. Thanks to a wide measurement range, TF current sensors cover a wide current range from 100 to 6000 A, with only 6 references. TF flexible current sensors can be used with DIRIS Digiware I modules, DIRIS A-40 and DIRIS B.

Advantages

Plug & Play

  • A rapid RJ12 connection makes wiring easy and reliable and prevents wiring errors. This also allows automatic detection of the sensor type and rating.
  • The sensors can be installed in both directions.

Accuracy according to IEC 61557-12

  • Class 0.5 for the global measuring chain (PMD + TF current sensors) from 2 to 120% of the nominal current In.
  • Accuracy is guaranteed regardless of the position of the conductor in the loop.

Safe locking mechanism

  • The locking system prevents the loop from opening, guaranteeing continuous functioning and accuracy even under harsh conditions.

Installation

  • The TF flexible sensor range is specially designed for existing installations with strict integration constraints or with high-intensity currents.

Simplified installation

  • The Rogowski integrator is directly integrated to the RJ12 cable enabling a quick and compact integration (no DIN rail assembly required) inside electrical panels.
  • The integrator is self supplied by the PMD through the RJ12 cable and does not need any external power supply.
