I. Model Explanation (330400-01-05)

330400: Standard accelerometer (50g, 100mV/g)

01: 1/4-28 UNF installation thread (standard)

05: 5m integrated three-core shielded cable, top outlet, industrial general type (non-explosion-proof)

II. Core Parameters (Electrical / Mechanical)

Electrical

Sensitivity: 10.2 mV/(m/s²) = 100 mV/g ±5% @100Hz

Range: ±490 m/s² (±50g) peak

Frequency Response: 10Hz～15kHz (±3dB); 30Hz～10kHz (±0.8dB)

Power Supply: -24V DC (-22～-26V), 2～10mA

Output: Differential voltage (including bias - 8.5V DC), directly connected to 3500/44 etc. monitoring cards

Lateral Sensitivity: ≤5% (axial)

Mechanical / Environmental

Shell: 316L stainless steel, IP67, airtight seal

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

Installation: 1/4-28 UNF external thread, any angle (horizontal / vertical)

Torque: 8～10Nm (71～89in-lbf)

Cable: 5m original non-shortable, three-core shielded, the longest extension can reach 150m

Impact Limit: 5000g peak

III. Standard Accessories

Sensor: 330400-01-05 (5m integrated cable, 1/4-28 thread)

Monitoring Module: 3500/44 acceleration monitoring card, 3300/50 vibration monitoring system

Extension Cable: 16710-XX (three-core shielded, select length as needed)

IV. Typical Applications

Rotating Machinery: Gearbox, compressor, turbine, high-speed motor (high-frequency vibration / gear mesh monitoring)

Conditions: High temperature, humidity, dust, corrosive environment (316L stainless steel + airtight seal)

Measurement Requirements: High-frequency (>1kHz) vibration, impact, gear failure (frequency response of speed sensor is insufficient)

V. Key Differences from 330500 (Speed Sensor)

Measured Physical Quantity: 330400 = Acceleration (g); 330500 = Speed (mm/s)

Frequency Response: 330400 = 10Hz～15kHz (high frequency); 330500 = 4.5Hz～5kHz (mid-low frequency)

Sensitivity: 330400 = 100mV/g; 330500 = 3.94mV/mm/s

Usage: 330400 = Gear / High-frequency Impact; 330500 = Bearing / Routine Vibration
