Description
Bently Nevada 190501-11-00-04 operates as a low-frequency, piezo-velocity sensor optimized for machinery protection. If you are monitoring cooling tower assemblies or air-cooled heat exchangers, this velocity transducer tracks casing vibration down to lower operational limits than a standard velomitor. It translates mechanical casing movement directly into a proportional analog signal for your machinery protection system.
Are you dealing with an immediate failure or performing preventive maintenance on a fan assembly? This unit is currently available to support your operational needs.

Bently Nevada 190501-11-00-04 Core Technical Specifications
Field engineers frequently deploy this specific configuration in cooling tower applications where fan rotational speeds sit between 100 and 300 rpm. The internal electronics integrate an accelerometer signal into velocity data, eliminating the mechanical wear points typical of moving-coil velocity sensors—though your mileage may vary depending on the exact rigidity of your mounting surface.
Part Number Configuration Breakdown
The alphanumeric structure reveals the hardware choices baked into this exact part number:

Well, technically the transducer works down to 90 rpm, but only if the surrounding structural resonance does not mask the signal. When mounting the casing sensor, ensure the spot face is clean, flat, and free of paint. If the face has uneven scoring, the high-frequency background noise can overload the internal charge amplifier, causing tracking errors.
Global Logistics, Trade, and Customs Information
Moving specialized diagnostic sensors across borders requires meticulous regulatory compliance. Because this transducer carries multiple global hazardous area certifications, international customs officials often verify the exact approval codes against import manifests to ensure environmental compliance.

Frequently Asked Questions
Can this sensor be connected directly to a standard 3500/42M monitor?
Yes. The 190501-11-00-04 interfaces directly with the Bently Nevada 3500/42M Proximitor Seismic Monitor module. Ensure that you select the correct transducer type inside the 3500 rack configuration software to align the voltage scaling with the sensor’s 100 mV/in/s output curve.
What happens if moisture gets into the MIL-C-5015 connection?
Moisture in the connection introduces an insulation resistance path that degrades the signal quality, typically causing the monitoring system to report a “Not OK” status or show erratic spikes. For cooling tower cells, using a boot-sealed cable or matching conduit housing is vital to block ambient water vapor.
Do you provide tracking and expedited shipping for critical outages?
We use tier-one carriers including DHL Express, FedEx, and UPS. Full digital tracking information goes out automatically as soon as the package clears our dispatch dock, letting you track the sensor right to your plant floor.
