T3RC Rogowski Coil Current Probes

Teledyne Test Tools Rogowski Current probes offer a broad range of products covering a wide frequency span and current measurement ranges for maximum application coverage whilst being easy to use in difficult to reach parts of the circuit.

The flexibility of the probe sense coil means that measurements can often be made without modification to the circuit under test, giving more accurate results, whilst remaining isolated, with very low insertion load of only a few pH.

The inclusion of both battery power and wall plug operation means that the Teledyne Test Tools Rogowski Current Probes are as happy working out in the field as they are working on the bench.

The T3RC0300-UM and T3RC0120-UM features our smallest cross section sense coil at only 1.7mm. This ideally lends itself to embedded power applications where it’s necessary to probe around the leg of power components such as inductors, capacitors or small switching devices as small as a TO220 MOSFET.

The T3RC0600-HF and T3RC3000-HF are general purpose Rogowski probes covering applications up to 600 Amps and 3000 Amps respectively. With extended high frequency coverage, 5 kV peak insulation and wide operating temperature range from -40C to +125C, makes them ideally suited to both general purpose as well as wide temperature environments.

The T3RC3000-LF and T3RC6000-LF Rogowski probes offer an extended low frequency performance down to less than 1 Hz. The low frequency performance means that the maximum droop on low frequency pulses is typically 0.1% / ms or less, whilst offering our highest level of peak insulation of 10 kV and wide operating temperature range of -20C to +100C.

The T3RC0060-LF is our highest sensitivity Rogowski probe with an maximum measurement range of 60 Amps with a 2 kV insulation and a wide operating temperature of -20C to +100C.

• 7 different probes covering a wide range of applications.
• Maximum current measurement coverage up to 6000 Amps.
• Maximum voltage insulation up to 10 kV peak.
• Connect to a wall plug or use with batteries.
• Low loading of the circuit under test.
• Wide coil operating temperature from -40 C to +125 C on UM and HF probes
  -20 C to +100 C for LF probes.
• Use without modification to the DUT.

The Teledyne Test Tools Rogowski probes are compatible with all of the Teledyne Test Tools Oscilloscopes as well as the Teledyne LeCroy Oscilloscopes.

The Teledyne Test Tools Rogowski probes have a simple connection requirement of a BNC input with 1 MOhm impedance. These probes will therefore work with the majority of oscilloscopes in the market.

The probes can be made even more useful by using your Oscilloscope's Attenuation function to re-scale the Channel vertical range.
