Description

Configured for continuous vibration monitoring and trend logging on essential balance-of-plant machinery, the Bently Nevada 2300/20-KIT-003-00-00 (2300/20 Vibration Monitor Kit) provides direct physical/electrical execution. This self-contained monitoring package incorporates a dual-channel 2300/20 monitor unit along with a companion field termination block. The assembly ingests dynamic signals from proximity probes, accelerometers, or velocity transducers to process local machine metrics and deliver independent mechanical protection loop inputs directly to automated safety circuits.

Hardware Specifications

Machinery Monitoring and TSI Characteristics

The 2300/20-KIT-003-00-00 manages localized asset logging constraints within standard Turbomachinery Instrumentation (TSI) field packages. The internal analog circuitry maps incoming transducer sweeps through dedicated cross-talk suppression paths, ensuring high-frequency case accelerations do not bleed onto adjacent bearing displacement tracks. Onboard firmware implements precise scaling matrices tailored to the Velomitor 2-wire constant-current sensor signature. During operation, the monitor cross-references internal bias voltage validation profiles against standard transducer operating windows; if field wiring issues or internal sensor degradation shifts this bias voltage baseline, the monitor trips an internal hardware fault flag while maintaining continuous tracking of parallel rotor dynamics parameters and absolute shaft speed.

Frequently Asked Questions

Q: Does the 2300/20 monitor kit require an external computer platform to manage real-time safety relay actuation?

A: No. The 2300/20 operates completely standalone for machinery protection. The onboard microprocessor evaluates the configured alarm setpoints and executes latching or non-latching logic to drive the physical onboard SPDT relays independently of external network connectivity.

Q: How is the integrated 4-20 mA current loop configured to transmit calculated vibration variables to a plant DCS?

A: Each current loop tracks a dedicated dynamic channel and maps across a configurable full-scale window (e.g., 0 to 25 mm/s RMS or 0 to 1.0 in/s velocity). The monitor modulates the analog current loop parameters to match real-time overall amplitudes, providing continuous tracking metrics directly to the process control architecture.

Field Installation Guidelines

• Chassis Panel Mounting: Mount the 2300/20 monitor housing directly to a standard 35 mm metallic DIN rail inside a weather-proof, dust-isolated field enclosure panel. Verify the lower rail attachment latch engages securely to damp ambient mechanical vibrations originating from surrounding plant structural supports.
• Terminal Wiring Torque Restrictions: Connect field wiring leads ranging from 0.2 to 2.5 mm squared (24 to 12 AWG) to the matching terminal block screws on the interface block unit. Tighten terminal connection points to a maximum execution torque rating of 0.51 N-m (4.5 in-lb) to prevent strip-out while securing standard high-vibration connections.
• Shield Continuity and Noise Isolation: Route low-voltage analog sensor cables inside dedicated, grounded steel conduits separate from high-current AC motor supply lines. Terminate the external cable drain shield tape exclusively at the designated PE ground clamp on the 2300/20 chassis frame, leaving the field sensor junction ungrounded to block stray earth currents from corrupting internal conversion loops.
