For moving machine elements, the proximity system will allow for measurement that is contactless from the relative displacement. For measuring axial position and relative vibration for rotating machine shafts like those that are found in hydraulic, gas, and steam turbines. It can also be found in turbo-compressors, pumps, and alternators. The IQS 450 signal conditioner, and the TQ 402 or 412 non-contact transducer is what the system is completely based on . Each component is interchangeable and together they can be calibrated through the proximity system.
