II. Model Code Analysis (3300/16-XX-XX-XX-XX-XX-XX)

Take 3300/16-02-01-00-00-00-00 as an example:

3300/16: Dual-channel vibration monitor

02: Input type = Electromagnetic induction probe (standard)

01: Sensitivity = 8 V/mm (200 mV/mil, standard)

00: Frequency response = Standard (4–4000 Hz)

00: Range = 0–5 mil (0–0.127 mm)

00: Output = Standard (4–20 mA)

00: Special options = None

III. Core Parameters

1. Channels and Measurement

Number of channels: 2 independent (X/Y orthogonal or double gap)

Measurement quantity: Radial vibration (peak-to-peak), Axial clearance (DC voltage)

Input: Compatible with 3300 XL 8mm electromagnetic induction probe / Preamplifier

Sensitivity: 8 V/mm (200 mV/mil)

Linear range: 0.25–2.25 mm (8mm probe)

2. Electrical

Power supply: -24 VDC (±10%), approximately 12 mA

Frequency response: 4–4000 Hz (-3dB)

Accuracy: ±0.5 dB (vibration), ±1% (clearance)

Output: Each channel 4–20 mA (can be connected to DCS/PLC)

Alarm relay: 2 channels (warning / danger), contacts 5A @ 250 VAC

3. Mechanical

Size: 245 × 100 × 95 mm (rack-mounted)

Weight: Approximately 1.2 kg

Installation: 3300 standard rack (19", 3U)

4. Environment

Preamplifier: 330180 (standard), 330181 (high temperature)

Extension cable: 330130 (5m/9m)

Rack: 3300/05 or 3300/06 rack

V. Alternatives and Compatibility

Original factory replacement: 3500/40 (4 channels, more functions, direct replacement)

Compatible alternatives: 3300/16 new version (e.g. 3300/16-02-01-01-00-00-02)

Note: The old 3300/16 and 3500 racks are not compatible, and the entire cabinet needs to be upgraded
