ACM 150

Vacuum sampling system
The ACM 150 monitor samples up to 40 areas, which are scanned and analyzed in
sequence, as described in Air sampling system. The main assemblies are:
Bypass Venturi Pump Draws flow through sample tubes and bypasses the
flow to exhaust to provide a constant flow of fresh
sample to the monitor
Gas Cell Venturi Pump Evacuates the sampled air from the gas cell after it is
analyzed
Boost Pump (mechanical) Fills the evacuated gas cell with fresh sampled air for
each analysis cycle
Sample Valve Assembly Valves installed in the 10-port sample manifolds
(up to 40) that switch in sequence as the ACM 150
monitor scans the sample areas
Cycle Valve Assembly Group of 6 valves that control the flow through the
gas cell
Backup Exhaust Pump Normally idle, this mechanical pump backs up the
venturi pumps to provide operation in the absence of
CDA
Available outputs
The following output relays are dry contact, double-pole/double-throw (DPDT), rated
for 3 amps @ 30 VDC
