DM-102-NH₃ Ammonia Sensor

Detcon Model DM-102-NH₃ is a gas detection sensor designed to detect and monitor ammonia in air over the range of 0-100 ppm using electrochemical 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 ¾" 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 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.
