Detcon DM-100 Toxic Gas Sensor
The Detcon DM-100 series sensor features intelligent electronics, a non-intrusive operator interface and comprehensive fault diagnostics. The sensor is packaged in an electro-polished 316 stainless steel housing fitted with a ¾ 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 environments. Signal conditioning electronics are entirely 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 detection range. Upper enclosure options are aluminium and stainless steel.
Additional accessories include wireless communications and a loop-powered digital display. Each sensor is shipped with a splash guard with an integral calibration port. Detcon’s toxic gas sensors have a long shelf life and are supported by an industry-leading warranty.
