Page 4: Introduction
Page 4 (41) INTRODUCTION ADVANTAGES AND FEATURES During the recent years the mass production of different types of lasers has made them eco- nomically viable products for a broad range of applications, dust monitors among others. There are two main families of lasers: ... -
Page 5: Different Laser Models
Gas laser LM 3086, Semiconductor model LM 3188 and Superled model LX 3188. The basic models are LM 3086 and LM 3188. Both models function with the same principle measuring directly laser light extinction as optical density. Here is how they differ from each... -
Page 6: Applications For Different Laser Models
LM 3188 where the space is limited. LX 3188 Superled model can be used instead of LM 3188 where the measuring length is short enough (<2m) or where the price is of primary importance. THEORY OF OPERATION When a monochromatic light beam, such as laser beam, traverses through gas that contains particulate matter, the intensity of the beam will decrease by absorption and scattering pro- cesses within the particle distribution. -
Page 7: Opacity Definition
To account for many different applications and measurement set-ups the D-value as solved from the eq. (3), is the basic quantity for the MIP-monitors. Thus the indicator range is scaled in D-values and optical filters with known D-values are readily available to check the proper operation of the instrument. - Page 8 Page 8 (41) micrometers Where d = particle diameter = particle density grams/cm 3 meters L = measurement length in dust optical density D = measured D-value grams/m 3 M = mass concentration of dust This “mass formula”...

It has large operation range (0 … 90 %). Its optic need is minimum so there is less maintenance. LM 3188 has good stability and reliability. LM 3188 has both analogue and digital display in monitor unit. There are 4 operator selectable measuring ranges. Most of controls and displays are included in monitor unit. -
Page 10: Controls, Displays And Settings
Page 10 (41) CONTROLS, DISPLAYS AND SETTINGS The faceplate of the M 318 monitor unit is pictured which is below. Controls displays and settings are indicated by numbers 3.1.1 Indicating meter [1] Indicating meter, which displays the %-value in selected D-range. If, for instance, the reading is 40 % and the selected D-range is 0…0,3 D, then the measured D-value is 0,3 D ... -
Page 11: Zero Set Screw [3]
Page 11 (41) 3.1.3 Zero set screw [3] This is very important adjustment, which allows after installation to set zero (D-value) level. The zeroing should happen in as dustless condition as possible. When measuring path is clear of any interfering particles, the zero screw is turned until the meter (and display) indi- cates 0-reading. -
Page 12: Installation And Calibration
Page 12 (41) INSTALLATION AND CALIBRATION 4.1. INSTALLATION It is clear, that the installation environment is different in each application. That is why we pro- vide only a minimum of installation hardware with the instrument. The gas laser has a specific installation foot and semiconductor lasers as well as all receivers, come with the flanges that have elliptic holes for adjustment. - Page 13 Page 13 (41) 3: Use 10mm wrench to adjust position of the reveiver unit. (Version with upgraded purge air flow pictured). Main alignment adjustment should be done from transmitters installationg flange as shown on pictures 1 and 2. As the laser beam is very compact, only small holes (10…50 mm dia) to get beam through, are needed.
- Page 14 Factors 1 and 2 relates to measuring angle and inherent intensity fluctuation in both LM 3086 and LM 3188, as discussed in connection with mass density estimation. The mass formula can be used to estimate the mass concentration range, based on particle properties and path...

Page 15: Calibration
Page 15 (41) Factor 3 refers to allowed beam direction changes that can point the beam outside the detec- tor. The beam profile differs in He-Ne and semiconductor lasers. In the He-Ne laser, the criti- cal distance, where beam diameter exceeds the receiver active area, is around 13…18 m. For the semiconductor model this is 25…35m. -

R 318 surface. If this is no possible, then as near the receiver as possible. The indication of the LM 3188 should now increase to D+X, where X is the filter’s D-value giv- en in associated filter graphs, at the wavelength 655 nm. Use the filter consistent with the measurement range, ie. - Page 17 Page 17 (41) Next, use the same filter and the range 0…3,0 D and the result should now be: %-indication = 0,5 / 3,0 = 17 % Voltage output = 17 % 1 V = 170 mV Current output = 4mA + (17 % (20 - 4)mA) = 6,7 mA Note, that “zero”...
