Model 780FM-2-J88C Compact Sensor with Integral Cable
Brand: Wilcoxon Sensing TechnologiesThe top-exit Wilcoxon 100 mV/g integral cable sensor is designed for walkaround predictive maintenance applications. 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. The sensing element is housed in a case-isolated Faraday shield, providing maximum protection from RF interference. BNC termination provides easy connection to portable data collectors or handheld vibration meters.
A 316L stainless steel casing provides rugged durability for most extreme environments. The durable J88C coiled cable stretches up to six feet for quick and easy monitoring. An included twopole, 40 pound force pull-strength magnet provides maximum flexibility in the field.
