Teledyne Detcon 100 Toxic Gas Sensors

The Teledyne Detcon 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 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 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.

• Built-in Diagnostics
• Fully Encapsulated ITM Electronics
• Quick Thread Release (for sensor replacement)

Gases:

AsH3 B2H6 Br C2H4 C2H4O C2H6O C4H6 CH20 CH3OH CH4S Cl2 ClO2 CO GEH4 H2 H2S HBr HCl HCN HF N2H4 NH3 NO NO2 O2 O3 PH3 SiH4 SO2

The Detcon 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 aluminum and stainless steel (includes a transient protection terminal board). Additional accessories include wireless communications, a loop powered digital display. 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.
