DM-700-C2H2

Detcon Model DM-700-C2H2 is a non-intrusive “Smart” sensor designed to detect and monitor Acetylene in air over the range of 0-100 ppm using electrochemical sensor technology.

The intelligent plug-in, field replaceable cell provides automatic recognition of gas type and range, and features over-sized gold-plated connections that help prevent corrosion.

The Model 700’s rugged framework includes an intrinsically safe electro-polished 316 stainless steel housing with fully encapsulated electronics and dual layer surge protection. This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration, and transient spikes.

A primary feature of the Model 700 is embedded intuitive software that simplifies operator interface by guiding the user through routine calibration, configuration, and fault diagnostic functions using a built-in alpha/numeric display.

The Model 700 is equipped with standard analog 4-20mA, and Modbus™ RS-485 outputs. Among its unique features is a wireless option that can be used with Detcon’s SmartWireless® product line.

Additional integration options include a Remote Alarm Module (RAM), HART, and Foundation Fieldbus. Detcon’s toxic gas sensors have a long shelf life and are supported by an industry-leading warranty.
