Model 787A Low Profile General-Purpose Accelerometer
Brand: Wilcoxon Sensing TechnologiesWilcoxon’s side-exit 100 mV/g broadband sensor is ideal for monitoring machine vibration on a wide range of rotating equipment including motors, pumps, fans, compressors, turbines and generators. A 316L stainless steel casing provides rugged durability for the most extreme environments. The sensing element is housed in a case-isolated Faraday shield, providing maximum protection from ground loops and RF interference.
