Bently Nevada 2300/20-00 2300/20-CN 2300 Series Vibration Monitors With 4-20 Ma Outputs

Product Overview
The Bently Nevada 2300/20-00 is a compact, dual-channel vibration monitor designed for cost-effective protection of balance-of-plant assets such as pumps, fans, centrifuges and small motors. Measuring velocity or acceleration via industry-standard accelerometers or velocity sensors, the 2300/20-00 delivers a proportional 4–20 mA signal to existing DCS or PLC systems while providing on-board alarm relays for local shutdown logic. Its rugged IP66 aluminum housing, –40 °C to +85 °C rating and loop-powered design make it the preferred choice for harsh plant-floor environments where space, power and budget are limited.

Key Features & Benefits
• Dual independent channels—monitor two bearings or one differential measurement
• Field-selectable vibration units: velocity (mm/s, in/s) or acceleration (g)
• 4–20 mA output per channel, HART 7 protocol for remote configuration
• Two programmable alarm relays (SPDT, 5 A @ 30 V DC / 250 V AC)
• Loop-powered (10–36 V DC) – no additional power wiring needed
• Front-panel BNC and buffered raw outputs for portable analyzers
• IP66 / NEMA 4X aluminum enclosure, corrosion-resistant polyester coating
• –40 °C to +85 °C operating range and SIL 2 capability per IEC 61508 
• Quick DIN-rail or direct wall mounting with swivel sensor connector

Typical Applications
• Cooling-tower fans & HVAC blowers
• End-suction centrifugal pumps
• Small steam turbines & expanders
• Extruders & mixers in chemical plants
