Detcon The DM-700-O2 is a non-intrusive "smart" sensor designed to detect and monitor oxygen in the air over a range of 0 to 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 sturdy frame of the 700 model features an intrinsically safe, polished 316 stainless steel case with fully encapsulated electronics and double-layer surge protection. This innovative design virtually eliminates sensor failure due to water ingress, corrosion, vibration and transient spikes.
A key feature of the Model 700 is an intuitive, built-in software that simplifies the operator interface by guiding the user through the usual calibration, configuration, and troubleshooting functions using an alphanumeric display integrated. The Model 700 is equipped with standard 4-20 mA analog outputs and Modbus ™ RS-485 outputs.
Among its unique features, a wireless option can be used with the Detcon SmartWireless® product line. Additional integration options include a Remote Alarm Module (RAM), HART, and Foundation Fieldbus. Detcon's oxygen sensors have a long service life and are backed by a first-class warranty.
