Product parameters

Type: 5mm or 8mm diameter Proximity Probe, non-contact eddy current sensor (according to the 7200 series, the specific diameter needs to refer to the model configuration).

Measurement range: Linear range approximately 2 mm (80 mils), recommended gap setting -9 Vdc (approximately 1.27 mm / 50 mils).

Output: Analog voltage output, incremental scale factor (ISF) approximately 7.87 V/mm (200 mV/mil) ±5% (for 1-5 meter systems), deviation less than ±0.025 mm (±1 mil).

Frequency response: 0-10 kHz (+0, -3 dB), supports long-distance wiring (up to 305 meters).

Power supply: Compatible with Proximitor sensors, -17.5Vdc to -26Vdc (maximum consumption of 12mA).

Material: The probe housing is made of stainless steel (AISI 304), the cable is FEP insulated coaxial cable (75 Ω), without armor (02 indicates standard cable).

Environmental specifications: Operating temperature -35°C to +120°C (probe), relative humidity 100% condensation (non-immersion type); The IP rating is equivalent to IP67, resistant to vibration and shock.

Connector: Micro coaxial ClickLoc connector, gold-plated with brass.

Others: Minimum target size 15.2mm diameter, minimum shaft diameter 50.8mm; The cable length is 0.5 meters (05 indicates 0.5 meters / 19.7 inches).

Probe diameter: 5mm or 8mm (0.197in or 0.31in, specific model needs to be confirmed, default is 8mm).

Thread specification: 3/8-24 UNF or M10x1 (12 May indicate M10x1 thread), maximum thread engagement 14.3mm (0.563in) or 15mm; "02" may indicate a specific unthreaded length (such as 2 units in length).

Probe length: The overall housing length is minimum 20mm and maximum 250mm (customizable, usually 100-200mm; 02 configuration is approximately a short-length variant).

Cable outer diameter: 3.68mm (0.145in) standard.

Minimum bending radius: 25.4mm (1.0in).

Cable length: 0.5m (1.64ft, according to the 05 suffix).

The weight of the probe is approximately 323 g/m (11.4 oz/ft), and the total weight of the probe (including 0.5 m cable) is about 0.3 kg.

Extension cable: 34g /m (0.4oz /ft) without armor.

The entire system (probe + cable + sensor) : approximately 0.5 kg (1.1 lb) typical value.

Function

Proximity detection: Non-contact measurement of the distance to conductive targets, providing static (position) and dynamic (vibration) signal outputs for real-time monitoring of mechanical health.

Vibration and displacement measurement: Detect radial vibration, axial position and velocity, and support Keyphasor reference signal generation.

Signal processing: In conjunction with the Proximitor sensor, it provides filtering and amplification functions, with an output resistance of 50 Ω, supporting long-distance transmission without significant signal attenuation.

Compatibility: Interchangeable with 3300 XL series components, backward compatible with old systems; Built-in temperature stability and linear calibration, no need for frequent recalibration.

Protection function: Anti-electromagnetic interference (RFI/EMI), suitable for hazardous areas; Support differential pressure sealing (Viton O ring).

Application scenarios

Rotating equipment monitoring: It is used for vibration and displacement monitoring of fluid film bearing machines (such as turbines, pumps, fans and compressors) to prevent faults and reduce downtime.

Industrial automation: Integrated into Bently Nevada Monitoring systems, such as 3500 series racks, for Condition Monitoring in petrochemical, power generation and manufacturing industries.

Harsh environment: Suitable for sites with high temperature, high humidity or intense vibration, such as oil refineries, power stations or offshore platforms, supporting safety-critical applications in API 670 standard.

Maintenance optimization: Connect to the PLC/DCS system through output signals to achieve trend analysis, alarm triggering and predictive maintenance. The short cable (0.5m) is suitable for the layout of close-range sensors and is particularly suitable for compact installation Spaces.
