330878-91-05 Bently Nevada Proximity Sensor
Description
The 330878-91-05 is part of the Bently Nevada “3300 XL” (or similar)
Proximity/Proximitor sensor family, designed for non-contact
displacement (gap) measurement
of conductive targets (e.g., shafts, collars) in rotating
machinery.Specifically, the “3300 XL 50 mm” transducer system is
often referenced for
the 330878 series. The datasheet describes a system consisting of:
a probe (50 mm / some range), extension cable, and the Proximitor
(signal conditioning) sensor module. The table of suffix codes
(e.g., “-91-05”) typically encodes length/mounting
option (“91” = 9.0 m system length with DIN-rail mount) and
approval
option (“05” = multiple approvals) for that series.

FAQ |
Q1: What exactly does the 330878-91-05 measure?
A1: It measures the gap between the probe tip and a conductive target
(e.g., shaft, collar). That gap changes as the rotor moves,
vibrates, expands, or displaces. The sensor outputs a voltage
proportional to that gap/displacement. |
Q2: How linear and how far is its measurement range?
A2: For the 50 mm coil version (which the 330878 series belongs to)
the maximum linear range is up to ~27.9 mm (1.1 in). The output is
~0.394 V/mm for that range.Note: the usable “linear” portion might
be less depending on installation, target size, cable length,
ambient conditions.
|
Q3: What is the power supply and wiring requirement?
A3: Typical Proximitor sensors require a negative DC supply (e.g.,
-17.5 Vdc to -26 Vdc) and a load resistor of 10 kΩ, for the 50 mm
version. Field wiring: shielded triad cable recommended, cable
capacitance/inductance must meet spec to maintain performance.
|
Q4: Can I extend the cable length?
A4: Yes, but within limits: for example, the datasheet mentions a
maximum cable+probe length of up to ~9 m for the system length
(depending version) and cable capacitance/inductance loads must
remain under specified values to maintain hazardous-area
certification. Longer lengths possible but performance (frequency
response, accuracy) may degrade if spec >305 m cable or improper
cable type.
