Bently Nevada 74712-01-10-03-00 | Seismoprobe

Overview:

The Bently Nevada 74712-01-10-03-00 is a high-temperature two-wire transducer, designed to provide precise vibration measurements in harsh environments. This product is engineered to withstand extreme temperatures ranging from -29°C to +204°C (-20°F to +400°F), making it ideal for various industrial applications where durability and reliability are critical. Manufactured in the USA, the transducer is available with a Certificate of Origin (COO) upon request.

Key Features:

• High Sensitivity: 20 mV/mm/s (500 mV/in/s), ±5% when properly terminated.
• Wide Frequency Response: Operates from 4.5 Hz to 1000 Hz, with a typical +0, -3dB response.
• Temperature Range: -29°C to +204°C (-20°F to +400°F) for both operation and storage.
• Shock Resistance: Withstands up to 50 g peak acceleration along the non-sensitive axis.
• Transverse Sensitivity: ±10% of sensitive axis sensitivity at 100 Hz and 1.0 in/s.
• Durability: Anodized aluminum case and silicone gasket for reliable performance in harsh environments.
