Specs at a glance Measured variables: Scattered light intensity, dust concentration (after gravimetric comparison measurement) Process temperature: PVDF gas removal probe: ≤ +120 °C Hastelloy gas removal probe: ≤ +220 °C Versions for higher temperatures on request Certified measuring range: Dust concentration: 0 ... 7.5 mg/m³ / 0 ... 10 mg/m³ / 0 ... 15 mg/m³ / 0 ... 50 mg/m³ / 0 ... 100 mg/m³ / 0 ... 200 mg/m³ / 0 ... 500 mg/m³ ---------------------------------------- Field of application Endress Hauser's The FWE200DH dust measuring device is designed to continuously measure dust concentrations in wet gases. The gas is extracted via a gas sampling probe and heated above the dew point. Droplets in the gas vaporize, making it impossible for them to falsify the measurement results. The very sensitive scattered light measurement principle enables accurate measurements even at low dust concentrations. The FWE200DH meets the requirements of EN 14181 and EN 15267. • Monitoring of wet gas scrubbing facilities • Meassurement in very wet exhaust air and in technological processes • Measurement in wet gas downstream of desulfurization plants • For very low to medium dust concentrations • Gas sampling and return combined in one probe • Contamination check • Automatic monitoring of zero and reference point • Integrated system diagnostics for early detection of maintenance requirements Device properties:
