I. Model Explanation (330500-01-00)

330500: Velomitor standard piezoelectric velocity sensor (4.5Hz - 5kHz)

01: Installation thread 1/2 - 20 UNF

00: No integrated cable (bare probe, requires separate cable), no explosion-proof certification (industrial general type)

II. Core Parameters (Electrical / Mechanical)

Measurement type: Absolute vibration velocity (bearing box / casing)

Sensitivity: 3.94mV/mm/s (100mV/in/s) ± 5%

Frequency response range:

4.5Hz - 5kHz (±3dB)

6Hz - 2.5kHz (±0.9dB)

Range: 0 - 1270mm/s (0 - 50in/s) peak

Power supply: 24V DC (22 - 30V), ≤ 10mA

Output: Voltage signal (directly connected to 3500/42 etc. monitoring modules)

Shell: 316L stainless steel, IP67, rainproof and corrosion-resistant

Temperature: -55℃ - +121℃ (operation); -65℃ - +135℃ (storage)

Cable: No integrated cable, requires an additional 2-core shielded cable (maximum 305m)

Installation: 1/2 - 20 UNF thread installation, any angle (horizontal / vertical)

Installation torque: 11 - 14Nm (97 - 124in-lbf)

III. Standard Accessories

Sensor: 330500-01-00 (bare probe, 1/2 - 20 thread)

Monitoring module: 3500/42 seismic monitoring card, 3300/55 dual-speed monitoring card

Split cable: 021730-XX (2-core shielded, select length as needed)

Connector: 2-pin aviation plug (sensor end + module end)

IV. Typical Applications

Rotating machinery: pumps, motors, fans, compressors, gearboxes (rolling bearing equipment)

Conditions: humid, dusty, corrosive environment (no additional protective casing required)

General vibration monitoring in non-explosion-proof areas, replacing eddy current probes (unable to measure shaft vibration)

Requires on-site wiring or long-distance transmission scenarios (split cable is more flexible)

V. Key Differences from 330500-02-04 / 330500-03-01

Thread: 01 = 1/2 - 20 UNF; 02 = 3/8 - 24 UNF; 03=1/4-28 UNF

Cable: 00 = No integrated cable (separate); 01 = 1 meter; 04=4m

Torque: 01 = 11 - 14 Nm; 02 = 4 - 7 Nm; 03 = 8 - 10 Nm

Six. Selection Tips

330500-01-00: Suitable for projects that require custom cable length or where there is existing wiring on site. It offers lower cost and greater flexibility.

If you need factory-integrated cables, you can choose:

330500-01-01 (1m)

330500-01-04 (4m)
