For a process expansion, Amikon sourced hard-to-find sensors compatible with our DCS system, allowing integration without modifications or downtime.
During a packaging line optimization, Amikon's advice on sensor placement and controller choice improved efficiency and reduced errors.
A critical servo drive failure threatened to halt a robotics project, but Amikon shipped a replacement immediately and guided installation, keeping us on track.
In a multi-line plant upgrade, Amikon supplied PLCs, HMIs, and sensors for several areas simultaneously, and their updates kept all teams coordinated.
Product Features
7200 Series System Compatibility - Works directly with Bently Nevada 7200 series 5mm and 8mm proximity probe setups, nothing complicated, basically plug into the existing monitoring loop and it fits.
Precise 8.0-Meter Cable Length - Comes as 8.0m (-080) length, usually matched with standard 9-meter electrical loop designs so the installation side doesn’t need extra adjustment or guesswork.
50 Ohm Optimized Impedance - 50 Ω impedance is kept stable for vibration signal transmission, helps reduce signal loss when used in radial vibration measurement paths, especially in rotating machinery applications.
Non-Armored Flexible Design - Standard non-armored (-00) build, flexible enough for tight conduit routing. In real plant layouts, this makes installation less painful when space is limited.
API 670 Compliant Reliability - Built around API 670 expectations for machinery protection systems. Common in critical setups like ESD circuits, turbine monitoring, and other high-reliability protection loops where signal stability matters.
High-Temperature Plant Endurance - Rated for -34°C to +177°C, so it survives typical steam turbine and gas turbine environments without performance drift under long-term operation.
Versatile Sensor Interfacing - Used as an extension path between proximity probes and Bently Nevada 3300 or 3500 Proximitor monitoring systems. It’s not limited to one setup, usually works across multiple vibration monitoring configurations.
Trusted Power Plant Spares - Often selected as a spare part in steam turbine, gas turbine, and centrifugal compressor maintenance. Nothing fancy, but dependable when replacing worn or aging sensor cables in plant shutdown or overhaul cycles.
Applications
Steam & Gas Turbine Monitoring - Essential for continuous radial vibration and axial thrust measurement in power plant turbines.
Centrifugal Compressor Protection - Tracks shaft eccentricity and casing vibration to prevent catastrophic failures in critical compressors.
API 670 Machinery Protection Systems - Serves as a reliable signal linkage in API 670 compliant machinery protection loops.
Industrial Rotating Machinery Overhaul - Used as a direct-fit replacement spare during plant maintenance for high-speed industrial rotors.
Emergency Shutdown System (ESD) Integration - Provides critical proximity sensor data inputs required for emergency shutdown decisions.
Harsh Plant Environment Deployment - Designed for sensor signal routing through demanding fields like petrochemical refineries and mills.
3300 & 3500 Rack System Interface - Connects machine-mounted proximity probes to control room 3500/40 monitoring cards.
Frequently Asked Questions
Q: What is the primary function of the Bently Nevada 21747-080-00 extension cable?
A: Basically, it works as the link between a 7200 series 5mm or 8mm proximity probe and the Proximitor module. Nothing fancy, but it’s the part that keeps the vibration signal moving cleanly through the loop, whether you’re looking at radial vibration or axial thrust. If this connection gets unstable, the whole measurement chain starts to feel it.
Q: What do the specific suffixes in the part number 21747-080-00 stand for?
A: The naming is actually pretty straightforward once you’ve seen it a few times. “21747” is the base 7200 series cable family. “-080” just means 8.0 meters length, and “-00” is the standard non-armored version—so no stainless steel protection layer, more flexible instead. Usually chosen when routing space is tight.
Q: Is the 21747-080-00 extension cable compliant with API 670 standards?
A: Yes, it’s designed in line with API 670 requirements. In real plant use, that basically means it’s trusted in protection systems where reliability can’t be loose—ESD loops, turbine protection, and critical rotating equipment monitoring in power plants. Impedance matching and signal stability are part of that expectation.
Q: Can I use the 21747-080-00 cable in high-temperature industrial environments?
A: It can handle pretty harsh conditions, from -34°C up to +177°C. So steam turbine areas or gas turbine compartments are within its normal working range. The insulation and construction are made for long-term exposure rather than short bursts of heat.
Q: With which Bently Nevada monitoring systems is the 21747-080-00 compatible?
A: Most commonly used with the 7200 series transducer system, but in practice it also shows up in 3300 proximity systems and 3500 rack setups like the 3500/40 Proximitor Monitor. It’s one of those parts that tends to cross between systems as a spare, especially during maintenance or retrofit work.
Q: How does the length of the 21747-080-00 affect the total transducer system calibration?
A: The 8.0-meter cable is meant to pair with a 1.0-meter probe, so the whole loop comes out to 9.0 meters. That total length is what the Proximitor calibration expects, keeping the 50 Ω impedance behavior aligned with the measuring range. In real setups, this is more about keeping the system “in balance” than doing any adjustment on site.
