CJ135 | Control and amplifier circuit for wide range oxygen sensors

CJ135

Increased accuracy
especially in the lean region - the sensor resistance is measured and regulated to keep sensor temperature at a constant level

CJ135 is a control and amplifier circuit for the wide range oxygen sensors by Bosch, NTK or DENSO.

CJ135 supports the continuous regulation of Lambda in the range of ʎ= 0.65 to ∞ (air).

Benefits

Pump current control and measurement

Lambda measurement result via SPI interface

Nernst cell reference voltage source
