The WBAF-2 is a 2 channel wide band air-fuel controller
suitable for in-car or on-dyno use.
This
miniature controller is fully encapsulated
and completely waterproof and can
be mounted
in any engine compartment.
-
Measures actual air-fuel ratio or Lambda
-
Compatible with Methanol, Ethanol, Leaded
and Unleaded Gasoline. Sensor life is limited
when used with leaded gasoline. Our experience
is the sensor lasts from 10 to 50 hours of
run time on leaded gas, life depends on lead
content and number of heat cycles.
-
Easy free-air calibration proceedure
-
Uses the Bosch LSU 4.2 sensor which is accurate
and low cost.
-
Unlike many other wide bands, the WBAF-2 output does not vary when power supply voltage
changes. This is extremely important
in cars
running total loss ignition. Voltage
output
is constant with power supply voltage
of
11 to 16 volts.
-
Accuracy is better than +/- 0.1 AFR over
the full range.
-
Has 0 - 5 volt linear outputs for each channel
which are compatible with virtually
any data
logging system.
