Detcon Model Series DM-100 gas sensors are designed to detect and continuously monitor a long list of toxic gases in ambient air. Model DM-100 sensors provide a 2-wire loop powered 4-20 milliamp current signal equivalent to the sensor range of detection. Model DM-100 series sensors feature intelligent electronics and non-intrusive operator interface with automated calibration and comprehensive fault diagnostics. The sensor is packaged in an electro polished 316 stainless steel housing fitted with a ¾ inch NPT thread. 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. Upper enclosure options are aluminum and stainless steel. Additional accessories include a field replaceable transient protection circuit; a loop powered digital display, an alarm relay board 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.
