Detcon Model DM-100-CO is a gas detection sensor designed to detect and
monitor Carbon Monoxide in air over the range of 0-100 ppm using electro-
chemical sensor technology. Method of detection is by diffusion adsorption. Air
and gas molecules diffuse through a porous membrane contacting an electrolyte
solution which creates a change in electrical conductance between a reference
and measure electrode. This change in conductance is conditioned by internal
electronic circuitry to provide a linear 4-20 milliamp signal proportional to the
gas concentration.
Model DM-100 Series sensors feature intelligent electronics, non-intrusive
operator interface and comprehensive fault diagnostics. The sensor is packaged
in an electro-polished 316 stainless steel housing fitted with a 3⁄4 inch NPT
thread. The plug-in, field replaceable sensor cell features large surface area
gold-plated pins that reduce the effects of corrosion in harsh industrial environ-
ments. Signal conditioning electronics are completely encapsulated in the sensor
housing adding a high level of durability to the design. The packaging is
XP-intrinsically safe. This innovative design marks a return to a simple, more
affordable, and durable gas detection sensor without compromising quality.
Model DM-100 sensors provide a 2-wire loop powered 4-20 mA current signal
equivalent to the sensor range of detection. Upper enclosure options are alumi-
num and stainless steel (includes a transient protection terminal board). Addi-
tional accessories include wireless communications, a loop powered digital
display, Remote Alarm Module (RAM), HART, and a current to RS-485
converter. The standard serial converter is Modbus RTU. Each sensor is shipped
with a splash guard with integral calibration port. Detcon’s toxic gas sensors
have a long shelf life and are supported by an industry-leading warranty.
