Two New Compact Industrial Accelerometers for Online Monitoring and Portable Data Collection

Wilcoxon Research has introduced two full-performance, compact, industrial accelerometers: the 780B and 780C. These two new sensors join the 780A to create a family of narrow, low-profile, and lightweight sensors, ideal for walk-around collection of vibration monitoring data. The key difference between the three affordable accelerometers is the sensitivity tolerance, which customers can select based upon their application.

The 780A, 780B, and 780C are full-performance, 100 mV/g general purpose vibration sensors. The sensitivity tolerance is the primary differentiator between the 780A (+5%), 780B (+10%), and 780C (+15%). The 780 family of sensors has an 80 g acceleration range and a broad +3dB frequency response from 0.4 Hz to 14 kHz. The 780 family of sensors have a standard 2-pin, MIL-C-5015 connector that is compatible with the existing data collection infrastructure and fits the same connector used on the majority of industrial accelerometers.

The 780 family of accelerometers is ideal for route-based data collection because it is small and lightweight for easy handling. These compact vibration sensors fit in areas where space is at a premium and can also be used for permanent mounting in locations where a narrow diameter (less than 0.7 inches) is needed.

Characteristic of Wilcoxon vibration sensors, the 780 family of sensors are suited to even the harshest industrial environments. They are rugged, encased in 316L stainless steel, hermetically sealed, ESD protected, and EMI / RFI shielded. The 780 sensors operate normally at temperatures as low as -50º C and as high as 120º C.
