Features:
- Factory-Calibrated for Hitachi KT5916S0 – No Field Matching Required
- DIN Rail Mount with Integrated Electrical Isolation
- RFI/EMI Hardened for Unshielded Installations
The Bently Nevada 330180-X1-05 MOD 145004-10 leaves the factory with a specialized calibration curve optimized for Hitachi KT5916S0 target material. This eliminates the need for time-consuming field calibration or component matching, reducing installation labor by up to 60% compared to generic sensors. For Hitachi turbine operators, this ensures OEM-specified accuracy without compromising API 670 interchangeability requirements.
The X1 mounting option on the Bently Nevada 330180-X1-05 MOD 145004-10 includes a 35 mm DIN rail base with built-in electrical isolation. Unlike panel-mount versions that require separate isolator plates and four drilled mounting holes, the DIN clip snaps onto standard industrial rail in seconds. This design reduces cabinet space consumption by approximately 30% and allows dense packing of up to 8 Proximitor sensors per 12″ x 12″ housing.
Thanks to improved electromagnetic immunity circuitry, the Bently Nevada 330180-X1-05 MOD 145004-10 can be installed in fiberglass enclosures or directly on machinery without metallic conduit. This feature alone reduces material costs by $150-$300 per installation point while maintaining European CE Mark compliance. For retrofit projects where conduit routing is impractical, the sensor's 50 Ω output drives signals up to 305 meters of field wiring with only -3 dB attenuation at 10 kHz.
The 330180-X1-05 MOD 145004-10 Bently Nevada 3300 XL 8 mm Proximitor Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Hitachi Steam Turbines (Generator Drive): Mounted on bearing housings for radial vibration monitoring (X/Y probe pairs), as well as axial thrust position monitoring to prevent rubs and thrust bearing overload.
- Hitachi Gas Turbines (Compressor Drive): Installed on compressor section bearings to detect high-frequency vibration from blade pass events and low-frequency synchronous whirl. The 9-meter system length allows the Proximitor to be located outside the turbine enclosure, where ambient temperatures stay below +100°C.
- Hitachi Centrifugal Compressors (Process Gas): Used for both radial vibration and Keyphasor reference signals. The special KT5916S0 calibration ensures accurate shaft displacement measurement even when the compressor operates across wide temperature ranges (-35°C to +120°C at the probe tip).
- Hydrocarbon Processing Trains (Refinery & LNG): Deployed on Hitachi expander-compressor sets where API 670 compliance is mandatory. The ATEX/IECEx approval (05 option) allows direct installation in Zone 1 classified areas without additional explosion-proof housings.
- Proximity Probe Interface: The Proximitor accepts input from a 3300 XL 8 mm probe and extension cable, providing the necessary radio frequency excitation (approximately 1 MHz) to the probe coil. It demodulates the eddy current-induced impedance change into a linear DC voltage representing probe-to-target gap.
- Analog Output to Monitoring Systems: The conditioned -1 to -17 Vdc output (50 Ω source impedance) connects directly to Bently Nevada 3500 rack monitors (e.g., 3500/42M displacement/velocity module) or legacy 7200/3300 series monitors. For third-party DCS/SCADA integration, a signal conditioner or isolator with -24 Vdc power and 10 kΩ input must be used – standard 4-20 mA analog input cards will not read the negative voltage directly.
- Gap Voltage Indication: The terminal strip includes test pin holes that output the raw gap voltage for diagnostic purposes without disconnecting field wiring. Using the 148722-01 test plug, technicians can monitor gap voltage during machine startup to verify the probe remains within its linear range (typically -9 Vdc ±1 V for radial vibration applications).
- Cascade Integration with Safety Systems: For SIL 2/SIL 3 applications (IEC 61508), the Proximitor's output feeds into Bently Nevada 3500/53 overspeed protection modules or 3500/60 temperature monitors. The 9-meter system length does not degrade response time – frequency response remains flat (0 to 10 kHz, -3 dB) even with 305 meters of field wiring, provided triaxial shielded cable is used.
- Zero Gap Adjustment (Bench Calibration): When replacing a probe or extension cable, the system's overall sensitivity can be verified using a micrometer-actuated target. For the MOD 145004-10 calibration, the target must be Hitachi KT5916S0 material, not AISI 4140. Set the probe gap to 1.27 mm (50 mils) and adjust the monitor's zero potentiometer until the output reads -9 Vdc ±50 mV.
- Scale Factor Verification: Using the same test fixture, move the target in 0.25 mm (10 mil) increments across the linear range (0.25 mm to 2.3 mm). The output should change by 200 mV ±18 mV per step at 25°C. If deviations exceed tolerance, the Proximitor, probe, or cable may be damaged or mismatched.
- Barrier Selection for Intrinsically Safe Installations: When installing the 330180-X1-05 MOD 145004-10 with zener barriers, select barriers rated for -28 V Uo maximum and 140 mA Io maximum. The sensor's entity parameters are Ci = 47 nF, Li = 1460 μH. Do not use barriers that exceed these values – spark ignition risk exists.
