BENTLY NEVADA 21747-080-00 7200 SERIES PROBE EXTENSION CABLE

Product parameters

Type: Proximitor probe Extension Cable (Extension Cable), coaxial cable, used for signal transmission of eddy current sensors.

Compatibility: Specifically designed for 7200 series proximity probes and Proximitor sensors, it supports 8mm probe systems. Backward compatibility with 3300 XL series components.

Electrical specifications: Impedance 75 Ω, output resistance approximately 50 Ω; Supports analog voltage signal transmission (-17.5Vdc to -26Vdc), with a maximum current of 12 mA. The frequency response is 0-10 kHz (+0, -3 dB), with minimal signal attenuation (suitable for long-distance systems up to 305 meters).

Material: FEP insulated coaxial cable, with the inner conductor silver-plated copper and the outer sheath can be optionally equipped with stainless steel armor (standard without armor). The connector is a micro coaxial ClickLoc connector, gold-plated with brass.

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

Others: Minimum bending radius 25.4mm; Applicable to hazardous areas and supports API 670 standard; No sensor power supply function (only transmission).

Cable outer diameter: 3.68mm (0.145in) standard, without armor; 7.67mm (0.302in) with armor option.

Cable length: approximately 8 feet (2.4m, according to the 080 configuration variant; series standard options include 0.5m to 9m).

Connector size: Micro coaxial connector, with a diameter of approximately 10mm and a length of 20-30mm.

Minimum bending radius: 25.4mm (1.0in).

Overall system dimensions: Probes/sensors are not included. Cables are used independently.

Cable weight: approximately 34g /m (0.4oz /ft), without armor; The total weight (2.4 meters in length) is approximately 0.1 kg (0.22 lb).

Option with armor: approximately 103 g/m (1.5 oz/ft), total weight approximately 0.25 kg (0.55 lb).

The entire system (cable + probe + sensor) : approximately 0.7kg (1.5lb) typical value, depending on the configuration.

Function

Signal transmission: It provides low-loss coaxial transmission for both static (position) and dynamic (vibration) signals, reliable connection from the probe to the Proximitor sensor, and supports long-distance wiring without significant attenuation.

Compatibility and interchangeability: Seamlessly integrated with 7200 series and 3300 XL probes, supporting Keyphasor reference signals and vibration measurements; Built-in shielding to reduce noise interference.

Easy installation: The ClickLoc connector facilitates quick connection and disconnection. Supports differential pressure sealing and temperature stability to ensure signal integrity.

Diagnostic support: Assist the system in self-checking and troubleshooting, achieving precise monitoring through minimal signal distortion.

Protective function: Resistant to electromagnetic interference and environmental corrosion, suitable for industrial sites; No frequent calibration is required.

Application scenarios

Rotating equipment monitoring: It is used to extend the wiring of the vibration monitoring system, connect probes to sensors, monitor the radial vibration and displacement of turbines, pumps, fans and compressors, 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, especially suitable for installations that require additional cable length.

Maintenance optimization: Connect to the PLC/DCS system through reliable signal transmission to achieve trend analysis, alarm triggering and predictive maintenance. It is particularly suitable for system upgrades with limited space or remote sensor layout.
