Bently Nevada 200151-20-03-00 Accelerometer Standard Cable, 2.0m Armored

Product Introduction

When vibration monitoring cables fail due to harsh conditions, machine protection data is lost. The Bently Nevada 200151-20-03-00 accelerometer standard cable solves this with rugged construction and proven reliability. This 2.0-meter armored cable connects accelerometers to monitoring systems, ensuring uninterrupted signal transmission in demanding industrial environments.

Technical Specifications Breakdown

The 200151-20-03-00 is part of the 200151 model family, specifically configured as an Accelerometer Interface Standard Cable with connectors on both ends. The cable length is 2.0 meters (identified by the -20 option), providing flexibility for typical machine train installations. The -03 armor option specifies a blue cable with armor, offering mechanical protection against abrasion and impact. The -00 coupling nut is the standard version, ensuring secure mating to transducers and hardware. This cable uses a 4-conductor, 22 AWG construction with a braided shield and drain wire (85% coverage, minimum) and a PVC outer jacket, delivering excellent noise immunity and durability. The connectors provide an IP67 seal, preventing moisture and dust ingress, and are molded to the cable for robust strain relief. The addition of DC4 electrical insulating compound in the connectors adds extra protection against moisture during thermal shock. The minimum bend radius is 63.5 mm (2.5 in), allowing installation in tight spaces without damaging the cable. The operating temperature range is -20 ºC to +100 ºC (-4 ºF to +212 ºF), with a note that flexing below -20 ºC may cause damage; the cable can be used at lower temperatures if not flexed or bent.

Industry Applications

This cable is ideal for connecting Bently Nevada accelerometers in rotating machinery monitoring applications, such as turbines, compressors, pumps, and motors. In a refinery, the armored cable withstands exposure to chemicals and physical wear, while the IP67 seal protects against washdowns. In a power plant, the 2.0-meter length suits typical distances from sensor to junction box, and the wide temperature range accommodates both hot and cold environments. For a steel mill, the braided shield rejects electrical noise from variable frequency drives, ensuring accurate vibration data for predictive maintenance.

Installation & Setup Guidance

When installing the 200151-20-03-00, ensure the cable's minimum bend radius of 63.5 mm is respected to avoid internal damage. Route the cable away from sharp edges and high-heat sources. The connectors are keyed for correct orientation; align them carefully and tighten the coupling nuts by hand until snug. Do not use tools to over-tighten, as this may damage the seal. If the cable must pass through a conduit, use a suitable fitting to maintain the IP67 seal. For installations where the cable will be exposed to temperatures below -20 ºC, secure the cable to prevent flexing, as bending at low temperatures can damage the conductors.

Maintenance & Reliability

Regularly inspect the cable jacket for cuts, abrasions, or chemical damage, especially in harsh environments. Check the connector seals for signs of wear or contamination. The IP67-rated connectors provide excellent protection, but periodic verification of the seal integrity is recommended. The nickel-plated coupling nuts resist corrosion, but if the cable is frequently disconnected, inspect the threads for damage. The cable's PVC outer jacket and braided shield offer long service life, but replace the cable immediately if the shield or conductors are exposed. Following these practices minimizes downtime and extends the cable's operational life.

Selection Guide & Purchasing Advice

Before ordering the 200151-20-03-00, verify that your accelerometer and monitoring system use compatible connectors. The cable is designed for Bently Nevada accelerometers; confirm the mating hardware matches. If you need a different length, consider other options in the 200151 series. The armored version is recommended for environments with physical hazards; for standard duty, a non-armored option may suffice.
