Wilcoxon Research, a Meggitt group company and a leading supplier of quality vibration sensors and sensor networks, introduces 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.

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
• Operate normally at temperatures as low as -50º C and as high as 120º C

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.

"The 780B and 780C were designed to be a significant improvement over older models," said Tom Smith, Vice President of Sales and Marketing. "We have added EMI / RFI shielding, increased the acceleration range, expanded the frequency range, and improved the sensitivity tolerance, without significantly impacting the price." The 780B and 780C replace the 788A and 784A, respectively. The 788A and 784A will no longer be available for sale after a limited time.

Like other vibration sensors in Wilcoxon's extensive line of general purpose accelerometers, the 780 family of accelerometers is appropriate for vibration monitoring of most industrial rotating equipment, such as fans, motors, pumps, blowers, compressors, chillers, gearboxes, and mixers, to significantly reduce failure rates in the field. This machinery is commonly found in industries such as pulp and paper, nuclear power, power generation, petrochemical, oil and gas, food and beverage, chemical processing, pharmaceuticals, railway, steel making, and water and wastewater treatment.
