    Installation and commissioning MHM-97442 February 2023 Trigger wheel width Emerson recommends that the width of the trigger wheel should be larger than the diameter of the Hall effect sensor plus the expected axial displacement (see Figure 4-29). A smaller width of the trigger wheel may lead to the total signal loss if the axial displacement moves the trigger wheel out of the measuring range of the sensor.
