ECM offers seven
high-quality AFR modules suitable for applications where a
display is not required. Modules AFM1500, AFM1540 and F/A1500 output AFR
(or FAR) via a 0 to 5V linearized analog signal and AFR,
FAR, Lambda, and %O2 via a SMB (Serial Measurement Bus) interface.
The SMB interface allows serial communication with as many as
sixteen modules using a single RS-232 serial port from a computer and is fully compatible with ETAS INCA software.
Modules AFM1000 and F/A1000 output AFR (or FAR) via a 0 to 5V
linearized analog signal.
The DJET1000 outputs AFR to a DynojetTM dynamometer. The OXY6200 module is suitable for %O2 measurements in the
exhaust and intake of engines and outputs %O2 via a 1.1 to 5.5V
linearized analog signal.
All modules, except the AFM1540 come with NTK UEGO sensors.
The AFM1540 comes with a Bosch LSU 4.9 UEGO sensor and can be
user-reprogrammed to use a Bosch LSU 4.2 or NTK UEGO sensor.
The UEGO sensor has revolutionized AFR and %O2 measurement
because of its wide range, fast
response, and ease-of-use. The sensor consists of a spark
plug-sized electrochemical cell which is placed directly in
the engine's exhaust. The cell responds to O2, CO, H2, and
UHCs in the exhaust to determine AFR and FAR (inverse of AFR)
for fuels of any composition. All seven of ECM's AFR modules can
perform field calibration of the system using ambient
air.
