Model 780B/780C General-Purpose Compact Accelerometer
Brand: Wilcoxon Sensing Technologies
Wilcoxon’s top-exit 100 mV/g sensors are designed for monitoring areas with limited space. The general-purpose accelerometer is ideal for monitoring machine vibration on a wide range of rotating equipment such as motors, pumps, fans, compressors, turbines and generators.
A 316L stainless steel casing provides rugged durability for most extreme environments. The sensing element is housed in a case-isolated Faraday shield, providing maximum protection from ground loops and RF interference.
