The \u003cstrong\u003eBently Nevada 991-06-70-03-00\u003c\/strong\u003e Probe Vibration Transmitter offers a direct replacement for older axial vibration transmitters, delivering reliable 4-20 mA output for critical thrust measurements. Designed for DIN rail mounting, this transmitter accepts a single non-contacting 3300 NSv proximity probe and provides accurate linear output over a 0.6-0-0.6 mm full-scale range. The \u003cstrong\u003e991-06-70-03-00\u003c\/strong\u003e is built for harsh industrial environments with an operating temperature range of -35°C to +85°C and storage from -51°C to +100°C.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eBently Nevada 991-06-70-03-00\u003c\/strong\u003e delivers precise axial monitoring with these key parameters:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply:\u003c\/strong\u003e +12 to +35 Vdc input at transmitter terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Signal:\u003c\/strong\u003e 4-20 mAdc over specified full-scale range in 2-wire configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy:\u003c\/strong\u003e Within ±1.5% over full scale range (typical) from TEST signal input to voltage across 250 Ω loop resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Loop Resistance:\u003c\/strong\u003e 1,000 Ω including cable at 35 Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Limiting:\u003c\/strong\u003e 23 mA typical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero and Span:\u003c\/strong\u003e Non-interacting external adjustments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Defeat:\u003c\/strong\u003e Output goes to \u0026lt;3.6 mA within 100 µs after a Not OK condition; restores within 0.1 seconds after removal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.43 kg (0.9 lbm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003e991-06-70-03-00\u003c\/strong\u003e is specifically designed for axial thrust monitoring in large rotating machinery such as steam turbines, compressors, and pumps. Its 4-20 mA output integrates directly into PLC, DCS, or vibration monitoring systems for real-time protection and diagnostics. For replacement projects, the transmitter’s linear range of 0.25 to 1.65 mm (prox out) supports both 0.6-0-0.6 mm and 25-0-25 mils current loop ranges, making it compatible with existing probe systems.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup\u003c\/h2\u003e\u003cp\u003eMount the \u003cstrong\u003eBently Nevada 991-06-70-03-00\u003c\/strong\u003e on a standard DIN rail using the included DIN clips and screws (option 03). Connect one 3300 NSv proximity probe and extension cable to the input. Wire the 4-20 mA output to your monitoring system with a loop supply of +12 to +35 Vdc. Adjust zero and span using the non-interacting external trimmers. Ensure the loop resistance does not exceed 1,000 Ω at 35 Vdc to maintain accuracy. The signal defeat feature automatically indicates a fault by pulling output below 3.6 mA.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eWith no moving parts and a rugged enclosure rated for -35°C to +85°C operating temperature, the \u003cstrong\u003e991-06-70-03-00\u003c\/strong\u003e requires minimal maintenance. Periodic inspection of wiring connections and probe condition is recommended. The transmitter’s current limiting and fast signal defeat response enhance system reliability by preventing false readings during transient faults. Choose this model for long service life in continuous duty applications.\u003c\/p\u003e\u003ch2\u003eSelection Guide\u003c\/h2\u003e\u003cp\u003eWhen ordering the \u003cstrong\u003eBently Nevada 991-06-70-03-00\u003c\/strong\u003e, verify the full-scale option (-06 for 0.6-0-0.6 mm), system length (-70 for 7.0 meters\/23.0 feet), and mounting option (03 DIN clips and screws). Ensure your probe system matches the 3300 NSv series. PLC Source PRO, available through ubest101, stocks this exact configuration for fast delivery.
