Why would a technician use a thin flex current probe instead of a rigid clamp probe?

Thin flex probes wrap around large bus bars and cables that rigid clamps cannot grip; they also compress to fit around cables in tight breaker panels and conduit spaces.

How does Rogowski coil technology improve current measurement accuracy?

Rogowski coils measure current without magnetic saturation, providing accurate readings across a wide range of currents (from milliamps to 5000A) without the lag of ferrite core clamps.

Can the Fluke 3312 probe measure harmonics and high-frequency current content?

Yes, Rogowski coils are excellent for capturing harmonics up to the 50th harmonic, making them ideal for analyzing current distortion from VFDs, LED drivers, and other nonlinear loads.

Who benefits from the 122 cm flexible length of this probe?

Electricians working in cable trays, underground vaults, and confined spaces can use the extra reach to measure current without disconnecting or rerouting large conductors.

Can this probe be used for long-term monitoring installations?

Yes, Rogowski probes can remain clamped around a conductor for days or weeks, continuously measuring current for load studies and power factor analysis.

Is the 5000A rating suitable for main service entrance and large industrial feeders?

Absolutely; at 5000A, this probe covers utility feeds, large transformer secondaries, and main distribution bus bars in industrial and commercial buildings.

What lead time is typical for current probe accessories from Procure.ae?

Probes typically ship within a few weeks. Contact Procure.ae for availability and delivery timing to your location.

Can Procure.ae advise on which probe size and length suit my facility?

Yes, Procure.ae can discuss your power quality monitoring setup and help you select the right probe configuration.

What is the frequency response range of this Rogowski coil probe?

The probe accurately measures AC current from very low frequencies up to the 50th harmonic of 50/60 Hz supplies. For exact high-frequency limits, contact Procure.ae.

Does the 122 cm length allow measurement around very large diameter conductors?

The flexible probe wraps around most large bus bars and cable bundles. For specific diameter limits, confirm with Procure.ae before purchase.

What connector type does this probe use to attach to a power quality analyzer?

Confirm the connector compatibility (BNC, Mini-DIN, etc.) with Procure.ae to ensure it works with your analyzer model.

Fluke 3312PR-TF 5000A Thin Flex Current Probe 122 cm

Name: Fluke 3312PR-TF 5000A Thin Flex Current Probe 122 cm
Brand: Fluke
SKU: 3312-PR-TF-II

The Fluke 3312PR-TF 5000A Thin Flex Current Probe uses Rogowski coil technology to measure AC current from very low frequencies up to the 50th harmonic of a 50/60 Hz supply, with a flexible 122 cm head designed for installation around large conductors in confined spaces.

Overview

The Fluke 3312PR-TF is a 5000A thin flexible current probe based on the Rogowski coil principle, engineered specifically for use with the Fluke 1750 Power Recorder and compatible Fluke power quality instruments. Its lightweight, flexible 122 cm measuring head can be routed around large conductors and bus bars in locations where rigid jaw clamps cannot reach, making it the preferred choice for tight switchgear and distribution panel installations. Frequency coverage extends from very low frequencies up to the 50th harmonic of a 50/60 Hz supply, supporting comprehensive harmonic analysis in demanding power quality measurement tasks.

FAQ

Which instruments is the 3312PR-TF compatible with?
The probe is designed for the Fluke 1750 Power Recorder and the Fluke Power Quality/RPM Full Disclosure Power Monitor series. It is matched to allow users to set accurate scale factors directly on the instrument for reliable current readings.

Why choose the 122 cm version over the shorter model?
The 122 cm flexible head is suited to large conductors, bus bars, or cable bundles where the conductor circumference or the physical installation space prevents use of shorter or rigid jaw-type probes. The longer head also provides more flexibility when routing around awkward cable arrangements in switchgear panels.

Is this probe still available for purchase?
The 3312PR-TF has been discontinued by Fluke. Contact Procure.ae to request a quote for stock availability or for guidance on current Fluke Rogowski coil probes compatible with your power quality instruments.
