Bently Nevada 330101-02-21-10-01-00 3300 XL 8 mm Probe

330101-02-21-10-01-00: A Probe with a Documented DC Resistance

Most 3301xx variants are specified by geometry. This one carries a documented probe DC resistance of 7.59 ± 0.50 Ω, which is the figure that matters for cable run calculations on a long route — and it is the reason this variant appears in installations where the probe sits a long way from the monitor.

Decoded against the published configuration data: unthreaded length 0.2 in, overall case length 2.1 in, total length 1.0 meter (3.3 feet), miniature coaxial ClickLoc connector, probe DC resistance 7.59 ± 0.50 Ω, linear range 2 mm (80 mils), scale factor 7.87 V/mm (200 mV/mil), PPS tip, AISI 303/304 SST case.

Thread is 3/8-24 UNF and the probe is supplied without armor.

Why DC Resistance Is Specified on Long Routes

Probe DC resistance sits in series with the cable and the monitor input, so it contributes directly to the resistance the monitor sees across the loop. On a short route it is negligible; on a long route it is part of the budget that determines whether the signal arrives strong enough for the monitor to read correctly.

A tolerance of ± 0.50 Ω on 7.59 Ω is a real tolerance — about ±6.6%. On a route where the loop resistance matters, that tolerance belongs in the calculation rather than being assumed away.
