Assembly4.3 Mounting the acoustic emission sensorSITRANS DA400 for material flow monitoring with protection against explosion20 Operating Instructions, 09/2007, A5E00841152-012. Mount the device preferably at a right angle with the cable gland pointing downward.4.3 Mounting the acoustic emission sensorConditionTo mount the acoustic emission sensor, you need the following:● One hexagon socket-head screw M6x16● One positioning pin ∅ 3x10They are included in the scope of delivery.Mounting the acoustic emission sensor1. Mount each acoustic emission sensor individually on the pipe or chute.2. Mount the acoustic emission sensor preferably near a bend or in a position where a highsound level is produced by impact.NoteDo not mount the sensor in the vicinity of restrictive points, such as:• partially shut control valves• baffles• other places with reduced pressureThere is a good acoustic coupling if no elastic elements such as seals or the like are locatedbetween the sensor and the wall. Thus, there are good ferrous connections. The wall mustbe made of metal or some other highly sound conductive material.The acoustic emission is coupled to the sensor via the sensor base. Therefore, the housingfoundation must be uniformly even, smooth, and be at least as large as the sensor base.It is not permissible to have an air gap between the sensor base and housing or wall.If necessary, use a viscous lubricating grease to improve the coupling. The lubricatinggrease is not included in the scope of delivery.The following figure demonstrates an optimal mounting of the acoustic emission sensor:
