Accelerometers – Accelerometer sensors accurately measure vibration, shock, acceleration, motion for monitoring, control and testing applications. Accelerometers in Industry are primarily used to monitor the condition of rolling element bearings or ball bearings on rotating machinery such as fans, pumps, gears, compressors, turbines, paper machines, cooling tower fans and many other types of machinery. Accelerometers typically provide a dynamic signal output for use by condition monitoring systems including monitors, transmitters, analyzers and portable data collectors. Accelerometers are crystal based and convert mechanical motion to an electrical signal in the plant where they are mounted using the piezoelectric principal. Care must be taken with installation to insure proper operation to specifications. CIS Industrial Services offers General Purpose, Low Frequency, High Frequency and High Temperature Accelerometers in many different configurations. All Accelerometers are field proven. Accelerometers are also available in explosion proof (XP/IS) versions for hazardous area installations.
