Wilcoxon’s top-exit 100 mV/g, ±10% sensitivity tolerance broadband sensor provides long-lasting reliability at an economical price. The general purpose accelerometer is able to monitor machine vibration on a wide range of rotating equipment such as motors, pumps, fans, compressors, turbines and generators. 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. Mating the 786B-10 with Wilcoxon’s IP67 rated 2-pin MIL-5015 connector provides an ideal combination for online or permanent mount monitoring systems. Additional accessories are available including mounting pads, enclosures and portable vibration sources.
