Acceleration sensitive—measures total destructive shock
The 365A/E365A and 366 Vibraswitch malfunction detectors provide maximum protection for large motors, pumps, compressors and other rotating or reciprocating equipment by responding to mechanical malfunctions the instant they occur. Failing bearings, bent shafts, broken blades, overspeeding and similar malfunctions cause increased imbalance or high frequency vibration detectable with these Vibraswitches. The instruments may be wired to actuate an alarm or cause shutdown before costly damage occurs. They are designed for maintenance-free service in permanent installations and the 366 is for installations where weather-resistant enclosures are required.
