Description
The Bently Nevada 1701/05 is a dual-channel vibration monitor designed for the FieldMonitor system, specifically engineered to provide continuous machinery protection on smaller-scale assets or distributed skid-mounted equipment. It serves as the interface for either Proximitor sensors (radial vibration or axial thrust) or Seismoprobe/accelerometer transducers (casing vibration).
While many facilities are migrating to the 3500 or Orbit 60 platforms, the 1701/05 remains a vital component for maintaining balance-of-plant machinery like pumps, fans, and small compressors. We supply these modules to help plant maintenance teams avoid the massive capital expenditure of a full system upgrade when only a single monitor needs replacement.

Operational Insights & Field Application
How does the 1701/05 hold up in real-world plant conditions? In field deployments, we’ve found this module to be particularly effective for “remote” monitoring. Because the FieldMonitor architecture is distributed, the 1701/05 can be mounted in a small enclosure near the machine, which drastically reduces the length of high-impedance transducer cables that are prone to signal noise.
The 1701/05 is a two-channel unit, which is actually clever for small motor-pump sets—you can monitor one radial vibration point on the pump and one on the motor using a single module. However, don’t underestimate the setup requirements.
Well, technically it supports both proximity and seismic inputs, but you cannot mix a Proximitor on Channel 1 and a Seismoprobe on Channel 2 on the same 1701/05 module—so verify your sensor types match before installation. The hardware jumpers and software configuration must be uniform across both channels.
In my experience, if the “OK” LED is flashing or off, the first place to look is the transducer gap voltage. If your Proximitor is not gapped between -2 V and -18 V DC, the 1701/05 will flag a channel fault. Honestly, the most common “failure” reported by customers is actually just a field sensor that has drifted out of range, not a fault with the 1701/05 itself.
Global Trade, Shipping, and Logistics Optimization
Exporting specialized vibration monitoring hardware requires strict adherence to international trade regulations to prevent border delays.
Export Controls and Customs Documentation
We manage the entire compliance chain for your shipment. This hardware is classified under HS Code 9031.80.80, which covers “Measuring or checking instruments, appliances and machines.” We provide a full document suite—Commercial Invoice, Packing List, and Certificate of Origin (COO)—to ensure the shipment clears customs without being held for “technical evaluation” or “valuation disputes.”
Logistics and Transit
-
Preferred Carriers: We utilize DHL Express and FedEx International Priority. For these smaller modules, air express is the only way to go; it minimizes the time the electronics are exposed to the variable humidity of transit hubs.
-
ESD Protection: Every 1701/05 is shipped in an ESD-shieldive bag. We use double-walled corrugated over-boxing with anti-static foam to protect against the high-G impacts of automated sorting belts.
-
Incoterms: Standard terms are FCA (Free Carrier) or CIP (Carriage and Insurance Paid to).
Payment Risk Management
To facilitate international trade, we accept Telegraphic Transfer (T/T) for all orders. For large-scale facility maintenance contracts involving dozens of modules, we can coordinate through Escrow services or irrevocable Letters of Credit (L/C) to protect your procurement budget against cross-border risk.
Frequently Asked Questions
Does the 1701/05 come pre-configured? No. These modules are shipped with factory default settings. You must use the Bently Nevada 1701 Configuration Software to set your specific transducer scale factors and alarm setpoints. If you provide your configuration file, we can sometimes perform a pre-shipment upload for an additional service fee.
Can I use the 1701/05 in a 3500 rack? No. The 1701 series and 3500 series are entirely different architectures. The 1701/05 is designed specifically for the FieldMonitor terminal base and backplane.
What is the “OK” LED behavior during a fault? A solid green LED indicates the module is healthy and all transducers are within the “OK” window. A flashing green LED usually indicates the module is in “Configuration Mode” or “Bypass,” while an off LED signifies a hardware failure or a loss of power to the terminal base.
