The vibration monitoring industry has specialized jargon that is commonly used when talking about vibration sensors, accelerometers and associated applications. It's important that you understand common terminology to communicate effectively with vibration monitoring, reliability, condition monitoring and process automation professionals. We hope you find our glossary useful to find specialized terms and definitions used across vibration, condition monitoring and predictive maintenance.
Used when “setting up” a transducer to adjust the output signal to zero when zero load/pressure is applied.
The output signal of the transducer with rated excitation and with no-load applied, usually expressed in millivolts. Also called ZMO and zero pressure output.
ZERO MEASURAND OUTPUT (Zero Balance, ZMO)
A measure of the difference between the real output and the desired output of zero measurands from an instrument or system which is properly energized.
The difference in zero balance measured immediately before rated load application of specified duration and measured after removal of the load, and when the output has stabilized.
