Optimizing combustion efficiency and minimizing exhaust emissions are important for proper operation of nearly every industrial process that burns fuel. From cleaning burning natural gas to dirty coal fired kilns, the model 9060 provides reliable and efficient O2 monitoring capabilities by combining field proven zirconium oxide sensor technology with a powerful and versatile microprocessor based controller.
Calibration/Self Diagnostics
This analyzer provides standard programmable automatic calibration and auto-purge outputs. The user can program the cal/purge sequence to an alarm relay for external indication. It has also been designed with a probe diagnostic loop to continuously monitor for probe impedance to ensure the sensor is functioning properly. The electronics self-calibrate all inputs every minute.
Interface
The 9060 provides two isolated 4-20mADC linearized control signal outputs. One is dedicated to the O2 signal and the other is user selectable from thirteen other variables. In addition, an RS-232/ RS-485 printer/ computer interface capability is provided. One general diagnostic alarm and three field selectable alarms with switching are provided standard with this unit.
Setup
The analyzer’s functions and adjustments are easily accessed via a membrane keyboard. By using the prompting keys and following the display codes from the 2 line alphanumeric LCD screen, the user can easily interface with and set up the 9060 for field operation
Control Unit
The 9060 provides in-situ analysis capability which can accept signals from up to two zirconia probes for averaging or back up purposes in furnaces, kilns and boilers with the sample temperature ranging form ambient up to 1400°C. This unit is provided within a compact, steel, IP-54 (IP-65 without internal air reference pump), easily installed, gasketed enclosure suitable for wall mounting. Purged or explosion proof design enclosures rated for hazardous areas can also be supplied.
Reference Pump
An integral automatic reference pump is provided as standard with this unit. This pump draws atmospheric air and delivers it to the zirconium sensor as reference air in lieu of customer supplied instrument air. If the operator desires, the pump can be bypassed and instrument air, at a flow of 50 cc/min, can be delivered to the delivered to the sensor as required sensor as required.
