This 990 series transmitter accepts one 3300 NSv proximity probe and delivers a 4-20 mA signal directly proportional to shaft vibration. With its CSA Division 2 certification and 35 mm DIN rail mounting, it fits seamlessly into hazardous area installations.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications Breakdown\u003c\/h2\u003e\u003cp\u003eKey specifications of the 990-10-50-01-01:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-scale range:\u003c\/strong\u003e 0-10 mils pp (0-250 μm pp) – selectable for monitoring small to moderate shaft vibration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem length:\u003c\/strong\u003e 5.0 meters (16.4 feet) – pre-configured cable length for transmitter to probe connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e 35 mm DIN rail clips – quick, secure installation in standard panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAgency approval:\u003c\/strong\u003e CSA Division 2 – certified for use in potentially explosive environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e +12 to +35 Vdc at transmitter terminal – flexible input for a wide range of control systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum loop resistance:\u003c\/strong\u003e 1,000 Ω including cable at 35 Vdc – supports long cable runs without degradation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent limiting:\u003c\/strong\u003e 23 mA typical – protects loop components from overcurrent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.43 kg (0.9 lbm) – lightweight for easy handling and mounting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-20 mA accuracy:\u003c\/strong\u003e Within ±1.5% of full-scale range over specified conditions, ensuring precise process feedback.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 5 Hz to 6,000 Hz +0, 3 dB – captures essential machinery vibration frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal defeat (NOT OK):\u003c\/strong\u003e Output drops below 3.6 mA within 100 µs of a fault and recovers in 2-3 seconds after fault removal – failsafe design for alarm systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eReal-World Applications\u003c\/h2\u003e\u003cp\u003eThe 990-10-50-01-01 is ideal for continuous vibration monitoring on compressors, turbines, pumps, and fans in oil \u0026amp; gas, chemical, and power generation plants. Its 4-20 mA output directly interfaces with safety PLCs, distributed control systems (DCS), and dedicated vibration monitors, providing early warning of mechanical deterioration.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eFor accurate readings, gap the 3300 NSv probe between 0.5 and 1.75 mm (20 to 55 mils) from the target using a non-conducting feeler gauge. The 990-10-50-01-01 includes a 5.0 meter system length – ensure the probe cable does not exceed 3 meters for BNC output. Mount the transmitter on a 35 mm DIN rail within a suitable cabinet. Power with +12 to +35 Vdc; the loop resistance must be ≤1,000 Ω (including cable) at 35 Vdc. Connect a 250 Ω load resistor across the output for 1-5 V measurement. Current limiting (23 mA typical) prevents overcurrent damage.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003ePerform periodic inspections of probe gap, cable connections, and output response. The integrated NOT OK self-check instantly signals faults below 3.6 mA, reducing troubleshooting time. With proper setup and calibration checks every 12 months, the 990-10-50-01-01 delivers years of reliable service, minimizing unplanned downtime.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering the 990-10-50-01-01, confirm your application requires the 0-10 mils full-scale range, 5.0 meter cable, and 35 mm DIN rail mounting. For other options, explore alternate 990 series part numbers. Ensure your probe is the 3300 NSv series. For technical support or to order, contact PLC Source PRO (store link: ubest101.myshopify.com).
