The 991-06-50-01-05 is a specialized thrust transmitter designed to simplify axial position monitoring for OEMs and end-users. This specific model 991-06-50-01-05 is engineered to accept input from a Bently Nevada 3300 NSv (Narrow Side-view) proximity probe and its matching extension cable, forming a complete 5.0-meter (16.4-foot) system length.
As a 2-wire, loop-powered device, the 991-06-50-01-05 offers a straightforward and reliable interface for machinery control systems. It draws its operating power directly from the same 4-20 mA current loop used for signal transmission, eliminating the need for a separate power supply and simplifying wiring.
The 991-06-50-01-05 is equipped with a valuable diagnostic feature in addition to its primary 4-20 mA output. It provides a PROX OUT coaxial connector that supplies a non-isolated, dynamic transducer signal directly from the proximity probe. This allows maintenance personnel to connect portable, battery-powered diagnostic equipment to monitor raw vibration waveforms for troubleshooting machinery problems such as rubs or instabilities.
To ensure safe and accurate diagnostics, the use of a signal interface is strongly recommended when connecting to the PROX OUT of the 991-06-50-01-05. The 990/991 Test Adapter is specifically designed for this purpose. It conditions, inverts, and, most importantly, isolates the transducer signal from the 991-06-50-01-05 making it safe for use with AC-powered test equipment like oscilloscopes and analyzers.

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the primary purpose of the 991-06-50-01-05 Thrust Transmitter?
The 991-06-50-01-05 is designed to provide a simple, integrated solution for monitoring axial shaft displacement (thrust). It takes the signal from a 3300 NSv proximity probe system, conditions it, and outputs a standard 4 to 20 mA current signal proportional to the thrust position within its 0.6-0-0.6 mm full-scale range. This allows OEMs and users to easily feed thrust data directly into a machinery control system (DCS/PLC) for protection and logic.
What proximity transducer system is compatible with the 991-06-50-01-05?
The 991-06-50-01-05 is specifically designed to work with the Bently Nevada 3300 NSv (Narrow Side-view) Proximity Transducer System. It requires a compatible 3300 NSv probe and its matching extension cable to form the complete 5.0-meter system length specified for the 991-06-50-01-05. It is not designed for use with standard 8 mm or 5 mm 3300 probes.
Can I connect diagnostic equipment directly to the 991-06-50-01-05's PROX OUT port?
While the 991-06-50-01-05 provides a PROX OUT port for diagnostics, the signal is non-isolated from the 4-20 mA loop. Direct connection to AC-powered test equipment (e.g., oscilloscopes) is not safe and can damage equipment or compromise the loop. For safe diagnostics, the 990/991 Test Adapter is strongly recommended. It isolates, inverts, and conditions the signal from the 991-06-50-01-05 for use with standard analyzers.
What safety certifications does the 991-06-50-01-05 hold for use in industrial environments?
The 991-06-50-01-05 carries a comprehensive set of agency approvals, making it suitable for global use in various hazardous areas. These include CSA Division 2, ATEX Zone 0 and Zone 2 for explosive atmospheres, and ABS (American Bureau of Shipping) maritime approval for use on ships and offshore platforms.
