Detcon DM-700-O2 Oxygen Sensor
The Detcon DM-700-O2 by Teledyne is a non-intrusive “Smart” sensor designed to detect and monitor Oxygen in the air over the range of 0-25% by volume using electrochemical sensor technology. The plug-in, field-replaceable sensor cell is temperature compensated and features oversized 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 the 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 analogue 4-20mA and Modbus RS-485 outputs. Among its unique features is a wireless option that can be used with Detcon’s Smart Wireless product line.
Additional integration options include a Remote Alarm Module (RAM) and HART. Detcon’s oxygen sensors have a long shelf life and are supported by an industry-leading warranty.
Applications: Petrochemical, Refineries, Chemical plants, Confined Space Monitoring, Analyser Shelters, Wastewater treatment plants, Wet wells-dry wells, Pulp and paper, Food and beverage and Utilities.
