For landfill applications we offer a variety of monitor options ranging from single/dual channel units such as the AMC-1A series, to larger multi-channel units like the AMC-1400 and AMC-1800. For larger applications or facilities that require systems to integrate over BACnet our AMC-1DBx monitor can be tailored to suit.
Generally for this type of application there is a premium on ruggedness, so it is not uncommon for the equipment specified to be explosion-proof, even if not strictly required. For toxic gases such as nitrogen dioxide, carbon monoxide and hydrogen sulphide the AMC-210 series provides excellent value in a simple 2-wire 4-20 mA transmitter. If more advanced features are required the highly configurable AMC-DTR is a good option.
For combustible gas our AMC-360 Series and AMC-CSA-CAT great value options for monitoring combustible gases. If there is a requirement for more complex features, including display, non-intrusive calibration, or local relays then the AMC-DTR would be our recommendation.
