OMD-675 Online Trace Oxygen Analyzer - 1

OMD-675 Oxygen Analyzer Product Specification Sheet Online Trace Oxygen Analyzer w/ Integral Sample System 0 - 1 PPM Low Range; 0 - 25% High Range Resolution of 0.001 Parts-Per-Million Oxygen Integral Sample System w/ Bypass Valve Bi-Directional Communication Link Extensive Electronic Features & Outputs 19” Rack Mount Configuration Electrochemical Sensor Technology The OMD-675 is designed to measure trace oxygen in the sub 1 ppm region. The unit combines an advanced set of electronic features with our industry leading precision electrochemical oxygen sensor technology. The result is a highly reliable and cost effective design with an easy-to-use user interface. The analyzer comes with a 0 - 1 PPM full scale low range with a resolution of 0.001 ppm. The analyzer can also be configured for 0 - 1 ppm, 0 - 10ppm, 0 - 100ppm, 0 - 1000ppm and 0 - 25% in autorange or manual-range mode. The analyzer offers the user 2 different digital communication options, both of which are bi-directional. These come in the form of MODBUS RS485 ASCII or RS232. Alarm functionality comes in the way of 2 fully adjustable form C non-latching relay contacts. These can be configured as NO or NC and can be set as HIGH or LOW with optional delay mode. A power failure alarm is also standard and comes as a form C non-latching relay contact. The oxygen sensor used in the OMD-675 is based on the galvanic electrochemical fuel cell principal. All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict quality program. The standard cell (TO2-133T) is unaffected by other background gases such as H2, He, or Hydrocarbons. The optional acidic cell (TO2-233T) works well when acid gases such as CO2 or Natural Gas are present. The sensors are self-contained and minimal maintenance is required no need to clean electrodes or add electrolyte. Applications: Air Liquefaction and Separation Pure, Gaseous Hydrocarbon Stream Monitoring Gas Purity Certification Process Monitoring of Gaseous Monomers Semiconductor Manufacturing Protective Atmosphere Blanketing of Feedstock Specifications Accuracy: < +/- 1% of Full Scale Range* Alarms: (2) Adjustable Relay Contacts (1) Power Fail Relay Contact Analysis Range: 0-1/10/100/1000ppm/25% Calibration: Periodically Communication: Bi-Directional RS232 MODBUS RS485 ASCII Dimensions: 19.0 x 5.125 x 7.75 inch Display: Large with Backlight Enclosure: Brushed Stainless Steel Flow Sensitivity: 0.5 - 5 SCFH Gas Connections: 1/8” Compression Tube Output (Analog): 0 - 1V DC, 0 - 10V DC Isolated 4 - 20mA Power: 100 - 240 VAC Pressure: Inlet, 0 - 50 PSIG Range ID: 4 - 20 mA analog output 0 - 1 V DC analog output Response Time: T90 in 10 Seconds Sample System: Flow Control, 4-way sample / Bypass Valve, Flow Indicator Sensor: TO2-133T Trace O2 Sensor Sensor Life: 20 - 25 months Temperature: 0 - 50 deg C Temperature Compensation: Digital Warranty: 12 months Analyzer & Sensor Weight: 13.0 lbs *Accuracy at constant conditions Optional: Panel Mount Oxygen Configuration (OMD-677) [Dimensions: 10.78 x 7.47 x7.75 inch] TO2-233T Oxygen Sensor (for use in CO2) Designed, Tested, and Assembled in California, USA
