Wilcoxon Research, a supplier of vibration sensors and sensor networks, has introduced two full-performance, compact, industrial accelerometers.

The 780B and 780C sensors join the 780A to create a family of narrow, low-profile and lightweight sensors, ideal for the walk-around collection of vibration monitoring data.

The key difference between the three accelerometers is the sensitivity tolerance, which customers can select based upon their applications.

The 780A, the 780B and the 780C are full-performance, 100mV/g general-purpose vibration sensors.

The sensitivity tolerance is the primary differentiator between the 780A (+5 per cent), the 780B (+10 per cent) and the 780C (+15 per cent).

The 780 family of sensors has an 80G acceleration range and a +3dB frequency response from 0.4Hz to 14kHz.

Sensors in the 780 family have standard two-pin, MIL-C-5015 connectors that are compatible with the existing data collection infrastructure and fit the same connector used on the majority of industrial accelerometers.

The 780 family of accelerometers is suitable 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 0.7in or 18mm) is needed.

The sensors are suitable for harsh industrial environments.

They are encased in 316L stainless steel, hermetically sealed, ESD protected and EMI/RFI shielded.

The 780 sensors operate normally at temperatures as low as -50C and as high as 120C.

The 780B and the 780C replace the 788A and the 784A, respectively.

The 788A and the 784A will no longer be available for sale after a limited time.

As with other vibration sensors in Wilcoxon’s line of general-purpose accelerometers, the 780 family is appropriate for the vibration monitoring of most industrial rotating equipment, such as fans, motors, pumps, blowers, compressors, chillers, gearboxes and mixers to 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.
