Abstract

An inlet duct (101) to a gas turbine (not shown) has an inlet air filter (102). The filter is provided to remove dust from the inlet air flow (103), which can otherwise degrade the efficiency of the gas turbine and/or cause wear of the turbine. Associated with the duct is a filter monitor (1), having up- and down-stream probes (2, 3) mounted in the side wall (104) of the duct, one (2) upstream of the filter (102) and the other (3) downstream of it. Central to the monitor is a laser particle counter (4). Up- and down-steam sample lines (5, 6) lead from the probes to respective two-way, three-port, electro-actuated valves (7, 8), connected to an inlet (9) of the particle counter A pump (10) is provided at the outlet (11) of the counter A micro-controller (24) is connected to the valves (7, 8) for controlling their state in accordance with a sampling/purging cycle. Via data line (25), the micro-controller is connected to the particle counter (4).
