Measuring device for smoke spot number / dust concentration

D-R 300: Extremely sensitive device for measuring smoke spot number. D-R 300-40: Especially sensitive measuring device for the smallest concentration of dust, in particular in waste incineration plants.

Measuring principleThe D-R 300 / D-R 300-40 meters operate ac-cording to the scattered light method. The modulated light from a Halogen lamp illumi-nates the dust particles in the exhaust duct. The scattered light reflected from these particles is measured and assessed.

320D-R

Stray light measurement redefined

The light of a red laser diode (eye safe) illu-minates the dust particles in the measuring volume of the flue gas duct. The light is scat-tered by the particles and also generates background light in the stack. Scattered light plus background light are received in one half of the integrated dual detector.

At the same time the other half of the detec-tor receives only the background light from the same area of the stack, without the stray light portion.

After subtraction of the background light the pure amount of scattered light is avail-able. Since both parts of the integrated dou-ble detector share the same optics unit, no adjustment of the beam paths is necessary. The D-R 320 is ready for operation directly after mounting and can easily be operated at another measurement point.

The new DURAG dust monitor D-R 320 is based on the backscattering principle and is ideally suited for monitoring smallest to medium dust concentrations. The measurement takes place continuously in the flue gas stream. Naturally the D-R 320 is compliant with the high require-ments of the new European standards and therefore suitable for measurements according to official regulations.

Startup without adjustment due to unique optical design

The D-R 320 does not require a light trap. The background light in the stack is detected by means of a special optical system with dual de-tector and automatically compensated without the need of any manual adjustment.Advantage of this new design is the quick and uncomplicated installation, completely without adjustment at site. So the D-R 320 is ready for operation directly after installation and flexible for different applications. Even after a conver-sion to a different measurement point the de-vice is operational immediately again.

Long life due to integrated purge air monitoring and control

The D-R 320 is continuously purged and there-fore the optical system is not in contact with the exhaust gas. The integrated purge air control ensures the optimum amount of purge air. This ensures a long life and long maintenance inter-vals. A purge air failure is immediately indicated by the device. The maintenance of the device is minimal.

Convenient operation, readings anywhere accessible

The operation of the D-R 320 is comfortable and extremely flexible. Different operating options are available:

●● local via USB interface●● by means of the external operation unit

D-ISC 100●● remote access with RS-485 interface via

MODBUS RTU / MODBUS TCP protocol (acc. to VDI 4201-3)

Automatic control functions ensure reliable measuring values

Reliability has the highest priority when meas-uring emissions. For that reason the D-R 320 automatically performs zero and span check as well as contamination check in regular in-tervals and on demand. The device features an automatic contamination correction. Need for maintenance is immediately indicated by the electronics.

Options

●● Weather protection covers●● Fully integrated failsafe shutter as protection

for the measuring device in case of a purge air failure.

With the integrated fail safe shutter the D-R 320 is optimally protected for reliable use even un-der overpressure conditions.

Universal Operation Unit D-ISC 100

The universal operation unit D-ISC 100 allows for the connection of up to 8 DURAG measuring heads and enables the combination of dust and flow measurements. The D-ISC 100 offers con-venient operation and parameterization of the connected devices. The display provides an im-mediate overview of the current measurements and the status of the devices.

●● Connection of up to 8 measuring heads●● Local operation with keypad, through USB

port or remotely through RS-485 interface.●● Modular design, many extension modules

available

Single-sided installation on standard flanges without light trap

The D-R 320 allows single sided installation at the stack and requires just a small wall opening. It can be mounted in any orientation via a rotatable connection on existing DN 100 PN 6 or ANSI 4“ 150 lbs standard flanges. This reduces time and costs for installation.
