As a drop-in replacement or upgrade for older 3300 series systems, this transmitter integrates seamlessly with existing Bently Nevada 3300 NSv proximity probes. Its 4-20 mA output and DIN rail mount simplify installation in control cabinets, making it a reliable choice for turbine and compressor monitoring.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cp\u003eKey specifications from the product data include:\u003c\/p\u003e\u003cul\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\u003ePower Input:\u003c\/strong\u003e Requires +12 to +35 Vdc at the transmitter terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLinear Range:\u003c\/strong\u003e 0.25 to 1.65 mm for Prox Output; suitable for 0.6-0-0.6 mm or 25-0-25 mils current loop linear ranges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoop Accuracy:\u003c\/strong\u003e Within ±1.5% over specified full scale (typical) measured from TEST signal to voltage across a 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\u003eOperating Temperature:\u003c\/strong\u003e -35°C to +85°C\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\u003cp\u003eThe Bently Nevada 991-06-50-02-00 also features a \u003cstrong\u003eNot OK\/Signal Defeat\u003c\/strong\u003e function, dropping the output below 3.6 mA within 100 µs upon a fault condition, with recovery in 0.1 seconds.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eIdeal for axial position monitoring in steam turbines, centrifugal compressors, and large motors, this transmitter provides accurate thrust bearing wear detection. Its fast fault response protects critical machinery from catastrophic damage. The 0.6-0-0.6 mm full-scale option is well-suited for common thrust measurement ranges in power generation and petrochemical plants.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the Bently Nevada 991-06-50-02-00 on a standard DIN rail. Connect a single 3300 NSv proximity probe and extension cable to the input. Wire the 2-wire loop to a 4-20 mA receiver, ensuring that the loop resistance does not exceed 1,000 Ω at 35 Vdc. Use the non-interacting zero and span adjustments for calibration. The transmitter is designed for axial (thrust) measurement; position the probe accordingly.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eWith no moving parts and a robust sealed enclosure, the transmitter requires minimal maintenance. Regularly inspect the probe and cable for wear. The operating temperature range of -35°C to +85°C allows use in harsh environments. The signal defeat logic ensures fail-safe operation, reducing unplanned downtime. Periodic verification of loop accuracy (within ±1.5%) extends reliable service life.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing, verify your system requirements: confirm the probe type (3300 NSv), full-scale option (06: 0.6-0-0.6 mm), system length (50: 5.0 meters), mounting (02: bulkhead screws), and agency approval (00: not required). This unit is a direct replacement for earlier 991-series transmitters. For a reliable supply of genuine Bently Nevada 991-06-50-02-00 modules, contact ubest101. Ensure you have the necessary loop power supply (+12 to +35 Vdc) and a compatible 4-20 mA input card.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default","offer_id":44416689373283,"sku":"991-06-50-02-00","price":228.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.plcsourcepro.com\/products\/bently-nevada-991-06-50-02-00-industrial-automation-module","provider":"PLC Source PRO","version":"1.0","type":"link"}
