6 of 14 Operating Manual FS750E 3 Introduction The dust indicator FS750E is intended for the use at the clean air side to detect dust behind a filter. In this way, filter cracks, fractures or assembly errors are reported automatically and reliably.
Page 7 of 14 Operating Manual FS750E 4 System Design The system FS750E consists of a dust monitor and a DIN-rail transmitter. The sensor is connected to the transmitter via a 4-wire cable. The measured value of the particle load is then transferred to the transmitter and is available as 4-20mA signal at the analog output.
Operating Manual FS750E 6 Mounting Instructions 6.1 Selection of the mounting position The inlet and outflow zone for FS750E should not be less than 3 times the nominal diameter. After fixing the threaded sleeve in a 90° angle to the tube axis, the mounted weld must close the gap between the sleeve and the pipe wall reliably.

4-20mA range. 8.2 Calibration The FS750E is pre-calibrated by the manufacturer. The entire measuring range is mapped to the output range 4-20mA. There are two adjustment options for an individual customization of the analog output range.
Operating Manual Rev.: MSBA00049 Page 11 of 14 Operating Manual FS750E 1. Sensor Adjustment The amplification factor of the sensor can be adjusted by the gain switch (see figure 6). Figure 6: View of sensor board 2. Transmitter Adjustment The analog output range of the DIN-rail transmitter can be adjusted with the potentiometers ZERO and SPAN.
Rev.: MSBA00049 Page 14 of 14 Operating Manual FS750E 10 Service and maintenance When using the measuring device at abrasive materials, the product stream exposed areas must be regularly checked for their dimensions. The loss of material must not be more than 1mm.
