D-RX 250 Combined probe sensor

D-RX 250 Combined probe sensor

D-RX 250 is a 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.

Single rod measurement probe for simultaneous measurement of: *Dust concentration [mg/Nm³]*, *Volume flow [Nm³/h]*, *Temperature [°C]*, *Absolute pressure [hPa]*.

Only one probe / mounting hole in the exhaust duct. Allows calibration to measure the dust concentration in mg/m3. Compact design, no moving parts, no consumables. Allows calibration to flow in m3/h. LCD displays measured values. 4 analog output signals. Parameters are set at the control device without a PC. Control and evaluation unit can be located in a distance up to 1000 m.

Suitable for dust mass concentration measurement at:

Incineration in general ● Installations according 2000/76/EC WID / 17 BImschV ● Garbage, hazardous waste incinerators ● Facilities for cement production ● Iinstallations according 2001/80/EC LCPD / 13 BImschV / Clean Air Act ● Power stations with gas, oil, coal or co-firing ● Installations for the incineration of biomass ● Facilities pursuant to 27th BImschV.
