        Features:

        • Processes 3300 NSv proximity probe gap voltages into a linear 4-20 mA current output for thrust measurement.
        • Factory-calibrated to a full-scale axial displacement range of 0.6 to 0 to 0.6 mm (25 to 0 to 25 mil).
        • Includes a 35 mm DIN rail base and CSA/NRTL/C Class I Div 1 / Div 2 hazardous location certifications.
        Order configuration 991-06-70-03-05 specifies a 0.6-0-0.6 mm displacement scale, 7.0-meter system electrical length,35 mm DIN rail mounting bracket, and CSA/NRTL/C hazardous area safety rating.

        Engineered for direct control cabinet installation, this 2-wire loop-powered transmitter converts non-contact eddy current probe voltage signals into a 4-20 mA current loop without requiring rack-mounted monitoring hardware.

        Correct operation requires wiring to a matched 7.0-meter 3300 NSv eddy current probe and extension cable assembly to prevent measurement scale factor errors across the axial position range.

        Description
        The Bently Nevada 991-06-70-03-05 thrust position transmitter continuously converts non-contact eddy current probe voltage variations into a precise 4-20 mA DC current signal. Calibrated specifically for 7.0-meter total system electrical length setups with 3300 NSv proximity sensors, this unit bridges field-mounted transducer signals directly into control room automation networks without requiring intermediate signal conditioning chassis.

        Engineered to safeguard high-speed turbomachinery such as multistage pumps, steam turbines, and gas compressors, the Bently Nevada 991-06-70-03-05 provides early detection of excessive axial shaft displacement to protect thrust bearings from catastrophic wear. Its 2-wire loop-powered design simplifies panel architecture while an integrated front panel BNC port provides isolated, unfiltered dynamic signals for temporary connection to spectrum analyzers during routine predictive maintenance audits.

        Featuring a snap-on 35 mm DIN rail mounting bracket and CSA/NRTL/C Class I Division 1/2 safety ratings, the Bently Nevada 991-06-70-03-05 ensures dependable operation when installed inside field junction boxes or localized control panels. Built-in non-interacting zero and span potentiometers allow fast field loop verification, while clear protective covers guard the terminal block against accidental contact and environmental contaminants.

        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.
        VIEW ALL FAQS
        What is the power consumption requirement for operating the Bently Nevada 991-06-70-03-05 in a 2-wire loop circuit?
        The Bently Nevada 991-06-70-03-05 draws power directly from the loop, requiring a minimum supply voltage of +12 VDC up to +30 VDC under a maximum loop current limit of 23 mA.
        Can the full-scale range of the Bently Nevada 991-06-70-03-05 be reconfigured in the field?
        No, the 0.6-0-0.6 mm (25-0-25 mil) scale on option -06 is factory-calibrated during manufacturing and cannot be altered via field programming or hardware switches.
        How does the CSA hazardous area certification (option -05) affect electrical wiring for the Bently Nevada 991-06-70-03-05?
        Option -05 approves the Bently Nevada 991-06-70-03-05 for Class I Division 1 and Division 2 environments, requiring installation with certified intrinsic safety barriers or explosion-proof field enclosures per CSA installation drawings.
        What initial gap voltage should be set on the proximity probe before powering the Bently Nevada 991-06-70-03-05?
        The paired 3300 NSv probe must be mechanically set to its linear mid-span gap voltage (typically -10 VDC at mid-scale) before adjusting the non-interacting zero potentiometer on the Bently Nevada 991-06-70-03-05.
        Is special grounding required for the Bently Nevada 991-06-70-03-05 DIN rail mounting hardware?
        Yes, while the 35 mm DIN rail bracket (-03 option) provides mechanical support, the Bently Nevada 991-06-70-03-05 current loop shield must be grounded at a single point (typically at the control cabinet) to prevent ground loops.
        What details are required when inquiring about the Bently Nevada 991-06-70-03-05 Thrust Transmitter?
        Please provide the full part number 991-06-70-03-05, required quantity, target delivery date, and confirmation that your system uses 7.0m 3300 NSv proximity probes. Including a photo of your existing unit's nameplate is also recommended for replacement verification.
