Brand-Gaus - Model CL3020 -NOx Analyzer for Low-NOx Extractive CEMS
High performance, robust, solid-state chemiluminescence NOx detection make the CL3020 a great alternative to conventional photomultiplier-based NOx analyzers in both process control applications and conventional extractive CEMS. Options include our integrated oxygen measurement, continuous dual-cell speciation, and ammonia measurement. Building upon the success of our Model 7705, the Brand-Gaus Model CL3020 NOx Analyzer is the ideal choice for measuring NOx, NO, and NO2 concentrations in the most demanding monitoring applications.
Solid-state Chemiluminescence Detection
- High-sensitivity solid-state detector
- no delicate photomultipliers
- no high voltage power supplies
- no thermoelectric coolers
Greatly Simplified Electronics
Analyzer electronics and connectors are on a single electronics board, with ozonator, NOx detectors, power supply, and furnace control components mounted directly on the board
No board-to-board wiring and board-to-connector wiring
Robust Temperature-controlled Ozone Generation
Double-wall glass discharge tube with proprietary external flexible electrode, all encased in a temperature-controlled aluminum block.
Continuous, simultaneous, real-time NO / NO2 speciation
- Dual NOx detectors provide speciation without any switching time
- NO valves, no sample and hold delays, no settling time
- Directly measure ammonia using an external ammonia converter
Touch-screen interface
All diagnostics and controls accessible through an advanced, full-color 5” touch screen interface.
One-touch calibration
Once target gas values (e.g. bottle concentrations) have been entered, span and zero responses may be captured, and hence the analyzer calibrated, at the touch of the screen.
Trend-screen
Gas concentrations are plotted in a chart-recorder style trend with user settable scales for in-depth data analysis at a glance.
Diagnostics and alarms
critical component temperatures and gas flows are measured within the analyzer and reported on the diagnostic screen. Target values and alarmable deviations are user-settable. These alarms are displayed on the home screen, as well as warning messages for internal communication errors or if the converter or ozonator has been disabled.
Analog outputs
Each measurement, including dual ranges for NOx, is output as either 4-20mA or 0-10V (user selectable). Analog outputs can be forced to low (4mA/0V) or high (20mA/10V) for troubleshooting. Further, the gain and offset of these analog outputs may be trimmed within approximately +/-5% of full scale to compensate for offsets or other issues with an external the data acquisition system, independent of analyzer calibration.
QR-Code (2D barcode)
Analyzer configuration and operating parameters, including calibration settings, can be sent via any mobile device that has a QR code / barcode scanning app for ease in remote troubleshooting and support.
Digital Communications
MODBUS over TCP/IP included, allowing access to gas concentrations, diagnostics, alarms, and other instrument parameters. The
