Machine Guard MG4-REF11A Machine Guard MG4-REF11A is a continuous monitoring unit. It measures vibration severity (VIB) and the mechanical shocks (SPM) arising when the disc segments in a refiner touches each other. It provides, for each channel: • Status display (green - red light) and system fault (yellow light) •... -
Page 6: General
Machine Guard MG4-REF11 A General A contact of the disc segments can be prevented using the SPM Shock Pulse Method. A shock pulse transducer measures the mechanical shocks arising when the disc segments touches each other. A shock pulse transducer (A) is fixed to the refiner housing so that mecha nical shocks from the segments are transmitted to the transducer with a minimum of reduction. -
Page 7: Mechanical Installation
The temperature range of the MG4-REF11A is 0 to 50 °C (32 to 122 °F). The maximum length of the transducer cables is 100 m for SPM shock pulse transducers type 42000. SPM Instrument AB • Box 504 • SE-645 25 Strängnäs • Sweden Technical data are subject to change without notice. -
