Environmental & Physical Limits

• Operating Temperature Range: -55°C to 121°C (-67°F to 250°F).
• Temperature Sensitivity (typical): -14% to +7.5% over the operating range.
• Shock Survivability: 5,000 g peak maximum.
• Relative Humidity: up to 100% non-submerged; hermetic sealing protects the sensor.
• Base Strain Sensitivity: 0.005 in/s/mstrain.
• Magnetic Field Susceptibility: <51 min/s/gauss (50 gauss, 50-60Hz).
• Weight: 142 grams (5.0 oz) typical.
• Diameter: 25.3 mm (0.995 in).
• Height: 63.2 mm (2.49 in).
• Case Material: 316L stainless steel.
• Connector: 2-pin Mil-C-5015 hermetically-sealed with 316L stainless steel shell.
• Maximum Mounting Torque: 32-46 kg cm (24-40 in-lb).
• Polarity: case motion toward the connector makes Pin A positive versus Pin B.

Installation & Mounting Guidelines

• Use the 3/8 – 16 UNC mounting thread option -07 for secure installation.
• Apply a mounting torque between 32 and 46 kg cm (24-40 in-lb) maximum.
• Operate the 330500-07-02 only within -55°C to 121°C to avoid false readings.
• Follow drawing 167537 for hazardous area installations.
• Keep total cable length under 305 meters using Bently Nevada cable part 02173006.
• For high vibration (50g at 10 kHz), limit cable length to 63 meters (208 feet).

Frequently Asked Questions (FAQ)

• Q: Is the 330500-07-02 brand new and original?
