Suitability-tested and certified impact pressure system to measure velocity and volume flow of dry flue gas or process gas in pipes or ducts.

Measuring system for continuous evaluation of flow velocity and flow direction in tunnels. Ultrasonic sensors for tunnel ventilation control system. Reliable measurement across the tunnel profile. Two identical sensors alternately transmit and receive ultrasonic pulses. The system evaluates the transition times dependant on direction and calculates flow speed. D-FL 220T requires extremely low maintenance.

Extractive Automatic Measuring System (AMS) for continuous total mercury monitoring (CMM) in stack gas or process gas.

This pressure switch is a piece of equipment that needs to be integrated into an overriding control system. The pressure switch picks up a pressure and gives out a signal.

he D-VTA 200 Thermography Analysis System is developed, to work with all DURAG D-FS Furnace Sensors. Up to 8 Furnace Sensors can be connected to one D-VTA 200 System. Together with the Furnace Sensor, the software delivers online temperature distributions directly from the combustion chamber. The temperature range and the resolution are depending on the Furnace Sensor. Depending on the application different analysing software modules are available.

Self-monitoring and fail-safe control unit for the monitoring of gas, oil and coal flames with DURAG UV, UV+IR or IR flame sensors, primarily in single burner furnaces. suitable for intermittent operation, continuous operation and 72-hour operation according to TRD 604 LED display Installation on DIN-rail

Certified dust monitor, combined with a flow, temperature and absolute pressure measurement for monitoring of small to medium dust concentrations in dry flue gas and process gas.

The D-RC 120 is an automatic sampling device for gravimetric dust measurements to adjust or calibrate dust monitors for the measurement of dust in mgm3. The D-RC 120 extracts isokinetically a partial gas stream from the measuring gas duct whereas the extraction is controlled fully automatically. The partial gas stream is sucked through a filter in which the contained dust is deposited. The dust concentration is determined by weighing the filter before and after the extraction.

Suitability tested scattered light dust monitor for monitoring small to medium dust concentrations in dry flue or process gases. With its certification range of 0 ... 7.5 mgm3 the D-R 808 is ideally suited for monitoring very low dust concentrations.

Certified scattered light dust monitor to detect low to medium concentrations of dust in dry flue gas and process gas.

The D-R 320 is based on the back-scattered light principle. Thereby the light of a red laser diode illuminates the dust particles in the measuring volume of the flue gas duct. The light scattered backward by these particles is detected and evaluated. A unique feature of the D-R 320 is the automatic background light compensation with means of a patented optical system with dual detector. This allows for an easy and quick Installation without any adjustment. A light trap is not requir

The D-R 290 has been used successfully for more than 15 years in various applications as reliable and low maintenance opacity dust monitor. Now the new generation is available. The D-R 290 is a certified optical transmission monitor to measure the opacity or dust concentration of flue gases with medium to high dust concentrations. The D-R 290 operates using the double-pass method according to the auto-collimation principle. The light beam traverses the measuring path twice. The attenuation of the light beam by the dust content in the measuring section is measured and evaluated.

Compact and cost effective transmittance dust and opacity measuring device for monitoring medium to high dust concentrations in dry flue and process gas.
