Installation Guide Application and Design MHM-97883 June 2023 Application and Design The sensors The AMS EZ 1000 Sensors EZ105x-xx-xx-xxx, EZ108x-xx-xx-xxx, EZ116x-xx-xx-xxx are available in different variants. With or without the optional EZ190x-xxx extension cable. Order information for details. Figure 3-1 explains the parts of an AMS EZ 1000 Sensor.
Application and Design Installation Guide June 2023 MHM-97883 Which sensor type is applicable for a measuring application depends on several requirements such as desired measuring range, available measuring track, and maximum environmental temperature. Each AMS EZ 1000 Sensor requires an AMS EZ 1000 Converter to complete the measuring chain.
(see Requirements and hints for the sensor mounting). To measure shaft vibration, Emerson recommends using a sensor holder between bearing and turbine housing, as close as possible to the rotor. MHM-97883, Rev 1.07...

Installation Guide Installation and Mounting MHM-97883 June 2023 Ensure that the threads are clean and smooth-running. Do not bend or twist the sensor cable. If the sensor cable has an adapter plug, open To avoid touching the shaft during installation, the maximum distance between measuring target and sensor tip must be adjusted first.

These irregularities may cause changes in the converter output voltage which are not related to a real position or vibration signal. The signal caused by these irregularities is called runout. For the measuring track, Emerson recommends a surface finish of 0.41 µm to 0.76 µm.

Installation and Mounting Installation Guide June 2023 MHM-97883 • Always keep a distance between adjacent sensor cables to avoid mutual influence. Do not bundle sensor cables over a long distance. • Place junction boxes on a higher level than the sensor to stop oil from entering the cable protection tubes.
