Bently Nevada 2300/20-00-01
Full name: 2-Channel Vibration Monitor (independent DIN rail instrument, non rack mounted card)

2300/20 physical image
1、 Model code definition: 2300/20-00-01
2300/20: Basic model with 4~20mA analog output version
The first paragraph 00: No explosion-proof certification (explosion-proof version is CN/02)
Second paragraph 01: Authorization license, supporting access to System 1 diagnostic software
Comparison: 2300/20-00-00=No System1 authorization
⚠️ [Significant distinction]
2300 series ≠ 3500/3300 rack system
2300/20 is a standalone DIN rail mounted instrument and cannot be inserted into 3500/3300 racks; Mostly used for BOP auxiliary equipment such as pumps, fans, motors, etc., not for TSI protection of the main turbine/compressor core.
2、 Channel configuration
✅ Two universal vibration input channels (commonly known as dual channel vibration monitoring)
Compatible with three types of sensors:
3300XL eddy current preamplifier (shaft vibration, displacement)
Velomitor speed sensor (bearing housing vibration)
ICP piezoelectric accelerometer sensor
✅ Comes with an additional independent speed/key phase channel
Support eddy current key phase probes and magnetic resistance speed sensors; Can synchronously collect rotational speed for spectrum and frequency doubling analysis.

3、 Core hardware functions
Measurement type (optional software configuration)
Vibration velocity (effective value/peak value), acceleration, displacement peak to peak value; Support bandpass filtering and n-fold amplitude extraction
signal output
2-channel independent 4-20mA (built-in circuit power supply, directly connected to DCS)
2-channel programmable SPDT relay (alarm interlock)
3-channel BNC buffer signal output (2 vibrations+1 speed, for oscilloscope/acquisition instrument)
communication interface
10/100M Ethernet, supporting Modbus TCP; Authorized version can upload data to System 1
human-machine interface
Comes with LCD display screen, status LED, and local reset button
Power supply: 18-36 VDC (standard 24VDC)
Installation: Standard DIN rail buckle installation
4、 Applicable scenarios
Power plant/chemical auxiliary equipment: water pump, fan, induced draft fan, small gearbox, low-pressure air compressor;
Positioning: Economical continuous vibration monitoring+alarm protection, replacing old-fashioned 1900/27 monitoring meters.
For the core protection projects of the main steam turbine unit and large centrifugal compressor, the 3500 rack system is preferred according to regulations.
5、 Lifecycle information
Mainstream models available for sale by the original factory; There is sufficient stock of brand new original equipment, and the circulation of disassembled spare parts is relatively low
Warranty reference: Brand new original 12 months
