内置智能菜单界面允许用户通过板载菜单系统全面配置分析仪。 无需复杂的笔记本电脑或其他控制设备即可在现场设置分析仪。.
The analyzer comes standard with a 0 – 100% full scale range with a resolution of 0.01%. The analyzer can also be configured by the end user in the field for suppressed ranges of 50 – 100%, 70 – 100%, 80 – 100% and 90 – 100%. The analyzer comes with the ability to auto-range through all four ranges, this is accomplished with the choice of a voltage or current analog output.
Alarm functionality is performed by 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-775 is based on the galvanic electrochemical fuel cell principal and is compensated for both pressure and temperature giving the user added accuracy. All oxygen sensors are manufactured in house by Southland Sensing Ltd. under a strict quality program.
The analyzer is a cost-effective, yet similarly performing, alternative to paramagnetic oxygen sensors packaged in a 19” rack mount for easy installation and operation.
